1.  
Introduction  
The Atmel® CryptoAuthenticationfamily 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.
