+                This time can be observed through power profiling of the device,
+                making the ECDSA private key vulnerable to side-channel timing attacks.
+                This countermeasure masks the real ECDSA sign operation
+                under dummy sign operations to add randomness in the generated power signature.
+                It is highly recommended to also enable Secure Boot for the device in addition to this countermeasure
