CryptoAuthentication is Atmel’s first family of secure authentication ICs using the SHA-256 hash algorithm with a
256 bit key length, providing robust hardware authentication at a very cost effective price. With CryptoAuthentication
AT88SA102S and AT88SA100S developers can easily implement secure authentication and validation of physical or
logical elements in virtually all microprocessor based systems using the straightforward 256 bit challenge/response
protocol. It is ideal for handheld electronic systems or any embedded system where space is a premium with features
such as a tiny 3-pin SOT23 package and a single wire interface.
Implementing CryptoAuthentication’s host side IC provides a full system solution. The host chip off-loads key storage
and the execution algorithms, significantly reducing both system cost and complexity. When using the host IC, systems
designers no longer need to develop the cryptographic algorithms for their systems.
