Introduction

The Atmel^®AT88SA102S is a member of the Atmel CryptoAuthentication family of

cost-effective authentication chips designed to securely authenticate an item to

which it is attached. It can also be used to exchange session keys with some

remote entity so that the system microprocessor can securely encrypt/decrypt data.

Each AT88SA102S chip contains a pre-programmed serial number which is

guaranteed to be unique. In addition, it has been designed to permit secure

personalization so that third parties can build devices containing an OEM secret

without concern for the theft of that secret.

It is the first small standard product to implement the SHA-256 hash algorithm,

which is part of the latest set of recommended algorithms by the US Government.

The 256-bit key space renders any exhaustive attacks impossible.

The CryptoAuthentication family uses a standard challenge response protocol to

simplify programming. The system generates a random number challenge and

sends it to the Atmel® AT88SA102S chip. The chip hashes that with a 256-bit key

using the SHA-256 algorithm to generate a keyed 256-bit response which is sent

back to the system.
