Preliminary

Introduction

The AT88SA100S is a small authentication chip that can be used to

validate battery packs and other replaceable items that contain a

power source. It uses the industry leading SHA-256 hash algorithm

to provide the ultimate level of security.

An industry leading key length of 256 bits prevents exhaustive

attacks while multiple physical security features prevent

unauthorized disclosure of the secret key stored within the chip.

This key is automatically erased when power is removed from the

device.

It is shipped with a guaranteed unique 48 bit serial number that is

used in combination with an input challenge and the stored secret

key to generate a response that is unique for every individual

device.

The chip also includes 80 one-time fuses that can be used to

configure the system and/or retain permanent status. The values in

these fuses can also be locked to prevent modification.
