Crypto Stack - Key Exchange Configuration

Yetkin — Fri, 02 Feb 2024 10:44:19 GMT

Hi,

I need to implement ECDH (Eliptic Curve Diffie Hellman) to perform key exchange. However, there is no CRYPTO_ALGOFAM_ECDH parameter for CryptoPrimitiveAlgorithmFamily in Crypto Driver configurations, because I am using AUTOSAR 4.3. Is there a way to implement ECDH in accordance with AUTOSAR 4.3 or I have to use Ed25519 ?

Hi @Yetkin,

There are no S32K3 packages for AUTOSAR 4.3

With ECDH for AUTOSAR 4.4, I attached an example built on the SAF85_S32R41_RTD_0_9_0_D2207 package. You can port this example for the S32K3 RTD package.
