Description

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.

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
