Product Details

The ATECC508A crypto element integrates Elliptic Curve Diffie–Hellman key agreement, which makes it easy to add confidentiality to digital systems including Internet of Things nodes used in home automation, industrial networking, accessory and consumable authentication, mobile and other applications. The ATECC508A has ECDSA sign-verify capabilities built-in to provide secure asymmetric authentication. The combination of ECDH and ECDSA provides all three pillars of security: confidentiality, data integrity and authentication when used with MCU or MPUs running encryption/decryption algorithms in software.

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
Elliptic Curve Support
