Topic: [SOLVED] interoperating w/ Android Trusted Execution Environment (TEE)
My embedded device needs to securely exchange data with an Android smartphone app that uses the TEE. TEE apps use NIST P256-R1 curve. So my embedded device running wolfCrypt needs to perform ECHD (elliptic curve diffie helman) and support the ECDSA signature algorithm. For ECDH, can I simply create a keypair using wc_DhGenerateKeyPair() or do I also need to call wc_DhSetKey() and specify P256R1? If so, how is the curve specified? I'm new to WolfCrypt so any help is appreciated!
