The ECDSA peripheral before ECO5 of esp32h2 does not perform the ECDSA sign operation in constant time. This allows an attacker to read the power signature of the ECDSA sign operation and then calculate the ECDSA key stored inside the eFuse. The commit adds a countermeasure for this attack. In this case the real ECDSA sign operation is masked under dummy ECDSA sign operations to hide its real power signature |
