- Add ECDSA peripheral chapter and instructions to program efuse key block
- Update security guide for ECDSA peripheral mention for device identity
- Link with ESP-TLS guide about using ECDSA peripheral in TLS connection
- Technical details covered in section "15.3.2 Anti-DPA Attack Security
Control" chapter of the ESP32-C6 TRM
- Default configuration sets the security level low for the DPA
protection
- This change applies to all the crypto peripherals where the clock
frequency is dynamically adjusted to create randomness in the power
consumption trajectory
- This configuration helps to make the SCA attacks difficult on the
crypto peripherals
Simple flash read command is not supported if Secure DL mode is enabled on the target.
