Encryption Module Microchip ATECC608A | RAK5814

The RAK5814 is a crypto module using the Microchip ATECC608A crypto chip. It integrates ECDH (Elliptic Curve Diffie Hellman) security protocol, an ultra-secure method to provide key agreement for encryption/decryption, along with ECDSA (Elliptic Curve Digital Signature Algorithm) sign-verify authentication. Product Features Cryptographic co-processor with secure hardware-based key storage Protected storage for up to 16 Keys, certificates or data ECDH: FIPS SP800-56A Elliptic Curve Diffie-Hellman NIST standard P256 elliptic curve support SHA-256 & HMAC hash including off-chip context save/restore AES-128: encrypt/decrypt, galois field multiply for GCM Turnkey PRF/HKDF calculation for TLS 1.2 & 1.3 Ephemeral key generation and key agreement in SRAM – Small message encryption with keys entirely protected Full ECDSA code signature validation, optional stored digest/signature – optional communication key disablement prior to secure boot Encryption/Authentication for messages to pre
