Hello

just see the  LPC55S69 support ECC function, does it mean include the ECDSA、ECDH support also?

Hi @Tedlai99 

The LPC55S69 microcontroller includes hardware acceleration for ECC-based cryptographic operations through its CASPER and HASHCRYPT modules. These accelerators significantly improve performance for ECC algorithms, including:

- ECDSA (Elliptic Curve Digital Signature Algorithm)

Supported for signing and verification using secp256r1 curve.

- ECDH (Elliptic Curve Diffie-Hellman)

Supported for key exchange using secp256r1.

For more, see UM11126, Chapter 49 CASPER
