AES-SID as instantiated with CMAC can be more specifically described as AES-CMAC-SID. Uncaught failures could happen with alternative implementations of AES. Ideally, I would like to leverage this library as well for my own purpose. This is an implementation based But assuming this is just for testing development and that you currently don't need real randomness, then you can configure mbedTLS to use seed from flash by defining MBEDTLS_ENTROPY_NV_SEED and doing as described here, or even define MBEDTLS_TEST_NULL_ENTROPY which is the simplest. 2 - Abstraction Summary: This patch adds support for mbedTLS as a crypto backend for libssh. 5.
