Introduction

The Atmel^®CryptoAuthentication family of chips is the first cost-effective

authentication devices 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 Atmel AT88SA10HS host version of CryptoAuthentication chips is capable of

validating the response coming from the SHA-256 engine within an authentic

CryptoAuthentication client (SA100S or SA102S), even if that response includes

within the computation the serial number of the client. For detailed information on

the cryptographic protocols, algorithm test values and usage models refer to “Atmel

AT88SA100S” and “Atmel AT88SA102S” Datasheets, along with the application

notes dedicated to this product family.

The host CryptoAuthentication performs three separate operations (named HOST0,

HOST1 & HOST2) to implement this validation. The AT88SA10HS chip takes both

the challenge and response as inputs and returns a single Boolean indicating

whether or not the response is valid, in order to prevent the host chip from being

used to model a valid client.

The host system is responsible for generating the random challenge that is sent to

both the client and host CryptoAuthentication devices as AT88SA10HS does not

include a random number generator.

Note:

The chip implements a failsafe internal watchdog timer that forces it into a very low

power mode after a certain time interval regardless of any current activity. System

programming must take this into consideration. Refer to Section 4.5 for more details.
