The ATECC508A crypto element is the first crypto device to integrate ECDH (Elliptic Curve Diffie–Hellman) key agreement, which makes it easy to add confidentiality (encryption/decryption) to digital systems including Internet of Things (IoT) nodes used in home automation, industrial networking, accessory and consumable authentication, medical, mobile and other applications. In addition to ECDH, the ATECC508A has ECDSA sign-verify capabilities built-in to provide highly secure asymmetric authentication.

Additional Features: Easy way to run ECDSA and ECDH Key Agreement
ECDH key agreement makes encryption/decryption easy
Ideal for IoT node security
Authentication without the need for secure storage in the host No requirement for high-speed computing in client devices Cryptographic accelerator with Secure Hardware-based Key Storage
Performs High-Speed Public Key (PKI) Algorithms
