config HAL_ECDSA_GEN_SIG_CM bool "Enable countermeasure for ECDSA signature generation" depends on IDF_TARGET_ESP32H2 default n help Enable this option to apply the countermeasure for ECDSA signature operation This countermeasure masks the real ECDSA sign operation under dummy sign operations to add randomness in the generated power signature. This countermeasure is only necessary for ESP32-H2 < v1.2.
