TinyCrypt Cryptographic Library
###############################
Copyright (C) 2017 by Intel Corporation, All Rights Reserved.
Overview
********
The TinyCrypt Library provides an implementation for targeting constrained devices
with a minimal set of standard cryptography primitives, as listed below. To better
serve applications targeting constrained devices, TinyCrypt implementations differ
from the standard specifications (see the Important Remarks section for some
important differences). Certain cryptographic primitives depend on other
primitives, as mentioned in the list below.

Design Goals
************
* Minimize the code size of each cryptographic primitive. This means minimize
the size of a platform-independent implementation, as presented in TinyCrypt.
Note that various applications may require further features, optimizations with
respect to other metrics and countermeasures for particular threats. These
peculiarities would increase the code size and thus are not considered here.
* Minimize the dependencies among the cryptographic primitives. This means
that it is unnecessary to build and allocate object code for more primitives
than the ones strictly required by the intended application. In other words,
one can select and compile only the primitives required by the application.
Important Remarks
*****************
The cryptographic implementations in TinyCrypt library have some limitations.
Some of these limitations are inherent to the cryptographic primitives
themselves, while others are specific to TinyCrypt. These limitations were accepted
in order to meet its design goals (in special, minimal code size) and to better
serve applications targeting constrained devices in general. Some of these
limitations are discussed in-depth below.
General Remarks
***************
* TinyCrypt does **not** intend to be fully side-channel resistant. Due to the
variety of side-channel attacks, many of them only relevant to certain
platforms. In this sense, instead of penalizing all library users with
side-channel countermeasures such as increasing the overall code size,
TinyCrypt only implements certain generic timing-attack countermeasures.
Specific Remarks
****************
* SHA-256:
* The number of bits_hashed in the state is not checked for overflow. Note
however that this will only be a problem if you intend to hash more than
2^64 bits, which is an extremely large window.
* HMAC:
* The HMAC verification process is assumed to be performed by the application.
This compares the computed tag with some given tag.
Note that conventional memory-comparison methods (such as memcmp function)
might be vulnerable to timing attacks; thus be sure to use a constant-time
memory comparison function (such as compare_constant_time
function provided in lib/utils.c).
* The tc_hmac_final function, responsible for computing the message tag,
cleans the state context before exiting. Thus, applications do not need to
clean the TCHmacState_t ctx after calling tc_hmac_final. This should not
be changed in future versions of the library as there are applications
currently relying on this good-practice/feature of TinyCrypt.
* HMAC-PRNG:
* Before using HMAC-PRNG, you *must* find an entropy source to produce a seed.
PRNGs only stretch the seed into a seemingly random output of arbitrary
length. The security of the output is exactly equal to the
unpredictability of the seed.
* NIST SP 800-90A requires three items as seed material in the initialization
step: entropy seed, personalization and a nonce (which is not implemented).
TinyCrypt requires the personalization byte array and automatically creates
the entropy seed using a mandatory call to the re-seed function.
* AES-128:
* The current implementation does not support other key-lengths (such as 256
bits). Note that if you need AES-256, it doesn't sound as though your
application is running in a constrained environment. AES-256 requires keys
twice the size as for AES-128, and the key schedule is 40% larger.
* CTR mode:
* The AES-CTR mode limits the size of a data message they encrypt to 2^32
blocks. If you need to encrypt larger data sets, your application would
need to replace the key after 2^32 block encryptions.
* CTR-PRNG:
* Before using CTR-PRNG, you *must* find an entropy source to produce a seed.
PRNGs only stretch the seed into a seemingly random output of arbitrary
length. The security of the output is exactly equal to the
unpredictability of the seed.
* CBC mode:
* TinyCrypt CBC decryption assumes that the iv and the ciphertext are
contiguous (as produced by TinyCrypt CBC encryption). This allows for a
very efficient decryption algorithm that would not otherwise be possible.
* CMAC mode:
* AES128-CMAC mode of operation offers 64 bits of security against collision
attacks. Note however that an external attacker cannot generate the tags
him/herself without knowing the MAC key. In this sense, to attack the
collision property of AES128-CMAC, an external attacker would need the
cooperation of the legal user to produce an exponentially high number of
tags (e.g. 2^64) to finally be able to look for collisions and benefit
from them. As an extra precaution, the current implementation allows to at
most 2^48 calls to tc_cmac_update function before re-calling tc_cmac_setup
(allowing a new key to be set), as suggested in Appendix B of SP 800-38B.
* CCM mode:
* There are a few tradeoffs for the selection of the parameters of CCM mode.
In special, there is a tradeoff between the maximum number of invocations
of CCM under a given key and the maximum payload length for those
invocations. Both things are related to the parameter 'q' of CCM mode. The
maximum number of invocations of CCM under a given key is determined by
the nonce size, which is: 15-q bytes. The maximum payload length for those
invocations is defined as 2^(8q) bytes.
To achieve minimal code size, TinyCrypt CCM implementation fixes q = 2,
which is a quite reasonable choice for constrained applications. The
implications of this choice are:
The nonce size is: 13 bytes.
The maximum payload length is: 2^16 bytes = 65 KB.
The mac size parameter is an important parameter to estimate the security
against collision attacks (that aim at finding different messages that
produce the same authentication tag). TinyCrypt CCM implementation
accepts any even integer between 4 and 16, as suggested in SP 800-38C.
* TinyCrypt CCM implementation accepts associated data of any length between
0 and (2^16 - 2^8) = 65280 bytes.
* TinyCrypt CCM implementation accepts:
* Both non-empty payload and associated data (it encrypts and
authenticates the payload and only authenticates the associated data);
* Non-empty payload and empty associated data (it encrypts and
authenticates the payload);
* Non-empty associated data and empty payload (it degenerates to an
authentication-only mode on the associated data).
* RFC-3610, which also specifies CCM, presents a few relevant security
suggestions, such as: it is recommended for most applications to use a
mac size greater than 8. Besides, it is emphasized that the usage of the
same nonce for two different messages which are encrypted with the same
key obviously destroys the security properties of CCM mode.
* ECC-DH and ECC-DSA:
* TinyCrypt ECC implementation is based on micro-ecc (see
https://github.com/kmackay/micro-ecc). In the original micro-ecc
documentation, there is an important remark about the way integers are
represented:
"Integer representation: To reduce code size, all large integers are
represented using little-endian words - so the least significant word is
first. You can use the 'ecc_bytes2native()' and 'ecc_native2bytes()'
functions to convert between the native integer representation and the
standardized octet representation."
Note that the assumed bit layout is: {31, 30, ..., 0}, {63, 62, ..., 32},
{95, 94, ..., 64}, {127, 126, ..., 96} for a very-long-integer (vli)
consisting of 4 unsigned integers (as an example).
* A cryptographically-secure PRNG function must be set (using uECC_set_rng())
before calling uECC_make_key() or uECC_sign().
Examples of Applications
************************
It is possible to do useful cryptography with only the given small set of
primitives. With this list of primitives it becomes feasible to support a range
of cryptography usages:
* Measurement of code, data structures, and other digital artifacts (SHA256);
* Generate commitments (SHA256);
* Construct keys (HMAC-SHA256);
* Extract entropy from strings containing some randomness (HMAC-SHA256);
* Construct random mappings (HMAC-SHA256);
* Construct nonces and challenges (HMAC-PRNG, CTR-PRNG);
* Authenticate using a shared secret (HMAC-SHA256);
* Create an authenticated, replay-protected session (HMAC-SHA256 + HMAC-PRNG);
* Authenticated encryption (AES-128 + AES-CCM);
* Key-exchange (EC-DH);
* Digital signature (EC-DSA);
Test Vectors
************
The library provides a test program for each cryptographic primitive (see 'test'
folder). Besides illustrating how to use the primitives, these tests evaluate
the correctness of the implementations by checking the results against
well-known publicly validated test vectors.
For the case of the HMAC-PRNG, due to the necessity of performing an extensive
battery test to produce meaningful conclusions, we suggest the user to evaluate
the unpredictability of the implementation by using the NIST Statistical Test
Suite (see References).
For the case of the EC-DH and EC-DSA implementations, most of the test vectors
were obtained from the site of the NIST Cryptographic Algorithm Validation
Program (CAVP), see References.

/**
* @file
* @brief Interface to a CBC mode implementation.
*
* Overview: CBC (for "cipher block chaining") mode is a NIST approved mode of
* operation defined in SP 800-38a. It can be used with any block
* cipher to provide confidentiality of strings whose lengths are
* multiples of the block_size of the underlying block cipher.
* TinyCrypt hard codes AES as the block cipher.
*
* Security: CBC mode provides data confidentiality given that the maximum
* number q of blocks encrypted under a single key satisfies
* q < 2^63, which is not a practical constraint (it is considered a
* good practice to replace the encryption when q == 2^56). CBC mode
* provides NO data integrity.
*
* CBC mode assumes that the IV value input into the
* tc_cbc_mode_encrypt is randomly generated. The TinyCrypt library
* provides HMAC-PRNG module, which generates suitable IVs. Other
* methods for generating IVs are acceptable, provided that the
* values of the IVs generated appear random to any adversary,
* including someone with complete knowledge of the system design.
*
* The randomness property on which CBC mode's security depends is
* the unpredictability of the IV. Since it is unpredictable, this
* means in practice that CBC mode requires that the IV is stored
* somehow with the ciphertext in order to recover the plaintext.
*
* TinyCrypt CBC encryption prepends the IV to the ciphertext,
* because this affords a more efficient (few buffers) decryption.
* Hence tc_cbc_mode_encrypt assumes the ciphertext buffer is always
* 16 bytes larger than the plaintext buffer.
*
* Requires: AES-128
*
* Usage: 1) call tc_cbc_mode_encrypt to encrypt data.
*
* 2) call tc_cbc_mode_decrypt to decrypt data.

*
* Overview: CCM (for "Counter with CBC-MAC") mode is a NIST approved mode of

*
* TinyCrypt CCM implementation accepts:
*
* 1) Both non-empty payload and associated data (it encrypts and
* authenticates the payload and also authenticates the associated
* data);
* 2) Non-empty payload and empty associated data (it encrypts and
* authenticates the payload);
* 3) Non-empty associated data and empty payload (it degenerates to
* an authentication mode on the associated data).
*
* TinyCrypt CCM implementation accepts associated data of any length
* between 0 and (2^16 - 2^8) bytes.
*
* Security: The mac length parameter is an important parameter to estimate the
* security against collision attacks (that aim at finding different
* messages that produce the same authentication tag). TinyCrypt CCM
* implementation accepts any even integer between 4 and 16, as
* suggested in SP 800-38C.
*
* RFC-3610, which also specifies CCM, presents a few relevant
* security suggestions, such as: it is recommended for most
* applications to use a mac length greater than 8. Besides, the
* usage of the same nonce for two different messages which are
* encrypted with the same key destroys the security of CCM mode.
*
* Requires: AES-128
*
* Usage: 1) call tc_ccm_config to configure.

/**
* @file
* @brief Interface to a CMAC implementation.
*
* Overview: CMAC is defined NIST in SP 800-38B, and is the standard algorithm
* for computing a MAC using a block cipher. It can compute the MAC
* for a byte string of any length. It is distinguished from CBC-MAC
* in the processing of the final message block; CMAC uses a
* different technique to compute the final message block is full
* size or only partial, while CBC-MAC uses the same technique for
* both. This difference permits CMAC to be applied to variable
* length messages, while all messages authenticated by CBC-MAC must
* be the same length.
*
* Security: AES128-CMAC mode of operation offers 64 bits of security against
* collision attacks. Note however that an external attacker cannot
* generate the tags him/herself without knowing the MAC key. In this
* sense, to attack the collision property of AES128-CMAC, an
* external attacker would need the cooperation of the legal user to
* produce an exponentially high number of tags (e.g. 2^64) to
* finally be able to look for collisions and benefit from them. As
* an extra precaution, the current implementation allows to at most
* 2^48 calls to the tc_cmac_update function before re-calling
* tc_cmac_setup (allowing a new key to be set), as suggested in
* Appendix B of SP 800-38B.
*
* Requires: AES-128
*
* Usage: This implementation provides a "scatter-gather" interface, so that
* the CMAC value can be computed incrementally over a message
* scattered in different segments throughout memory. Experience shows
* this style of interface tends to minimize the burden of programming
* correctly. Like all symmetric key operations, it is session
* oriented.
*
* To begin a CMAC session, use tc_cmac_setup to initialize a struct
* tc_cmac_struct with encryption key and buffer. Our implementation
* always assume that the AES key to be the same size as the block
* cipher block size. Once setup, this data structure can be used for
* many CMAC computations.
*
* Once the state has been setup with a key, computing the CMAC of
* some data requires three steps:
*
* (1) first use tc_cmac_init to initialize a new CMAC computation.
* (2) next mix all of the data into the CMAC computation state using
* tc_cmac_update. If all of the data resides in a single data
* segment then only one tc_cmac_update call is needed; if data
* is scattered throughout memory in n data segments, then n calls
* will be needed. CMAC IS ORDER SENSITIVE, to be able to detect
* attacks that swap bytes, so the order in which data is mixed
* into the state is critical!
* (3) Once all of the data for a message has been mixed, use
* tc_cmac_final to compute the CMAC tag value.
*
* Steps (1)-(3) can be repeated as many times as you want to CMAC
* multiple messages. A practical limit is 2^48 1K messages before you
* have to change the key.
*
* Once you are done computing CMAC with a key, it is a good idea to
* destroy the state so an attacker cannot recover the key; use
* tc_cmac_erase to accomplish this.

/**
* @file
* @brief Interface to CTR mode.
*
* Overview: CTR (pronounced "counter") mode is a NIST approved mode of
* operation defined in SP 800-38a. It can be used with any
* block cipher to provide confidentiality of strings of any
* length. TinyCrypt hard codes AES128 as the block cipher.
*
* Security: CTR mode achieves confidentiality only if the counter value is
* never reused with a same encryption key. If the counter is
* repeated, than an adversary might be able to defeat the scheme.
*
* A usual method to ensure different counter values refers to
* initialize the counter in a given value (0, for example) and
* increases it every time a new block is enciphered. This naturally
* leaves to a limitation on the number q of blocks that can be
* enciphered using a same key: q < 2^(counter size).
*
* TinyCrypt uses a counter of 32 bits. This means that after 2^32
* block encryptions, the counter will be reused (thus losing CBC
* security). 2^32 block encryptions should be enough for most of
* applications targeting constrained devices. Applications intended
* to encrypt a larger number of blocks must replace the key after
* 2^32 block encryptions.
*
* CTR mode provides NO data integrity.
*
* Requires: AES-128

* Usage: 1) call tc_ctr_mode to process the data to encrypt/decrypt.

/**
* @file
* @brief Interface to a CTR-PRNG implementation.
*
* Overview: A pseudo-random number generator (PRNG) generates a sequence
* of numbers that have a distribution close to the one expected
* for a sequence of truly random numbers. The NIST Special
* Publication 800-90A specifies several mechanisms to generate
* sequences of pseudo random numbers, including the CTR-PRNG one
* which is based on AES. TinyCrypt implements CTR-PRNG with
* AES-128.
*
* Security: A cryptographically secure PRNG depends on the existence of an
* entropy source to provide a truly random seed as well as the
* security of the primitives used as the building blocks (AES-128
* in this instance).
*
* Requires: - AES-128
*
* Usage: 1) call tc_ctr_prng_init to seed the prng context
*
* 2) call tc_ctr_prng_reseed to mix in additional entropy into
* the prng context
*
* 3) call tc_ctr_prng_generate to output the pseudo-random data
*
* 4) call tc_ctr_prng_uninstantiate to zero out the prng context

/**
* @file
* @brief Interface to an HMAC-PRNG implementation.
*
* Overview: A pseudo-random number generator (PRNG) generates a sequence
* of numbers that have a distribution close to the one expected
* for a sequence of truly random numbers. The NIST Special
* Publication 800-90A specifies several mechanisms to generate
* sequences of pseudo random numbers, including the HMAC-PRNG one
* which is based on HMAC. TinyCrypt implements HMAC-PRNG with
* certain modifications from the NIST SP 800-90A spec.
*
* Security: A cryptographically secure PRNG depends on the existence of an
* entropy source to provide a truly random seed as well as the
* security of the primitives used as the building blocks (HMAC and
* SHA256, for TinyCrypt).
*
* The NIST SP 800-90A standard tolerates a null personalization,
* while TinyCrypt requires a non-null personalization. This is
* because a personalization string (the host name concatenated
* with a time stamp, for example) is easily computed and might be
* the last line of defense against failure of the entropy source.
*
* Requires: - SHA-256
* - HMAC
*
* Usage: 1) call tc_hmac_prng_init to set the HMAC key and process the
* personalization data.
*
* 2) call tc_hmac_prng_reseed to process the seed and additional
* input.
*
* 3) call tc_hmac_prng_generate to out put the pseudo-random data.

/**
* @file
* @brief Interface to a SHA-256 implementation.
*
* Overview: SHA-256 is a NIST approved cryptographic hashing algorithm
* specified in FIPS 180. A hash algorithm maps data of arbitrary
* size to data of fixed length.
*
* Security: SHA-256 provides 128 bits of security against collision attacks
* and 256 bits of security against pre-image attacks. SHA-256 does
* NOT behave like a random oracle, but it can be used as one if
* the string being hashed is prefix-free encoded before hashing.
*
* Usage: 1) call tc_sha256_init to initialize a struct
* tc_sha256_state_struct before hashing a new string.
*
* 2) call tc_sha256_update to hash the next string segment;
* tc_sha256_update can be called as many times as needed to hash
* all of the segments of a string; the order is important.
*
* 3) call tc_sha256_final to out put the digest from a hashing
* operation.

* gf_wrap -- In our implementation, GF(2^128) is represented as a 16 byte

*
* X^128 + X^7 + X^2 + X + 1,
*
* which leads to the reduction formula X^128 = X^7 + X^2 + X + 1. Indeed,
* since 0 = (X^128 + X^7 + X^2 + 1) mod (X^128 + X^7 + X^2 + X + 1) and since
* addition of polynomials with coefficients in Z/Z(2) is just XOR, we can

*
* X^128 = (X^7 + X^2 + X + 1) mod (X^128 + X^7 + X^2 + X + 1)
*
* and the coefficients of the polynomial on the right hand side form the
* string 1000 0111 = 0x87, which is the value of gf_wrap.
*
* This gets used in the following way. Doubling in GF(2^128) is just a left
* shift by 1 bit, except when the most significant bit is 1. In the latter
* case, the relation X^128 = X^7 + X^2 + X + 1 says that the high order bit
* that overflows beyond 128 bits can be replaced by addition of
* X^7 + X^2 + X + 1 <--> 0x87 to the low order 128 bits. Since addition
* in GF(2^128) is represented by XOR, we therefore only have to XOR 0x87

* Controller-to-host event buffers. Events have one of two priorities:
* o Low-priority (BLE_HCI_TRANS_BUF_EVT_LO)
* o High-priority (BLE_HCI_TRANS_BUF_EVT_HI)
*
* Low-priority event buffers are only used for advertising reports. If there
* are no free low-priority event buffers, then an incoming advertising report
* will get dropped.
*
* High-priority event buffers are for everything except advertising reports.
* If there are no free high-priority event buffers, a request to allocate one
* will try to allocate a low-priority buffer instead.
*
* If you want all events to be given equal treatment, then you should allocate
* low-priority events only.
*
* Event priorities solve the problem of critical events getting dropped due to
* a flood of advertising reports. This solution is likely temporary: when
* HCI flow control is added, event priorities may become obsolete.
*
* Not all transports distinguish between low and high priority events. If the
* transport does not have separate settings for low and high buffer counts,
* then it treats all events with equal priority.

* This file defines circular queues. The other types of data structures:
* singly-linked lists, singly-linked tail queues, lists and tail queues
* are used from sys/queue.h
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A singly-linked tail queue is headed by a pair of pointers, one to the
* head of the list and the other to the tail of the list. The elements are
* singly linked for minimum space and pointer manipulation overhead at the
* expense of O(n) removal for arbitrary elements. New elements can be added
* to the list after an existing element, at the head of the list, or at the
* end of the list. Elements being removed from the head of the tail queue
* should use the explicit macro for this purpose for optimum efficiency.
* A singly-linked tail queue may only be traversed in the forward direction.
* Singly-linked tail queues are ideal for applications with large datasets
* and few or no removals or for implementing a FIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.

ESP-IDF UART HCI Controller
===========================
This is a BLE controller use UART as HCI interface.
It can do the configuration of UART number and UART baudrate by menuconfig.
## BLE HCI example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example start controller with uart hci.
It uses ESP32C2's Bluetooth controller.
In this example, two UARTs are used:
- UART0 is used as normal output or by IDF monitor
- UART1 is used to convey HCI messages
Pins 8, 9 are used as TxD, RxD PINs of UART1.
## How to use example
### Configure the project
```
idf.py menuconfig
```
### Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
```
idf.py -p PORT flash monitor
```
(To exit the serial monitor, type ``Ctrl-]``.)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
## Example Output
There is this console output when bleprph is connected and characteristic is read:
```
set nimble port tx:8, rx:9.
set baud:115200.
controller lib commit: [fb738d4]
controller rom commit: [3314f9d]
I (346) system_api: Base MAC address is not set
I (356) system_api: read default base MAC address from EFUSE
```
