Atmel has released a new low-cost, cryptographic battery authentication IC for mobile phones, cameras, portable power tools, and other battery-powered applications.
The AT88SA100S CrytpoAuthentication IC uses a SHA-256 cryptographic engine and a 256-bit key that cannot be cracked using brute force methods. It has a guaranteed unique 48-bit serial number stored permanently inside the chip and 88 one-time, user-programmable fuses that can be used for the storage of battery parameters or status information. The 256-bit key is stored in the on-chip SRAM at the battery manufacturer’s site and is powered by the battery pack itself. Physical attacks to retrieve the key are very difficult to effect because removing the CryptoAuthentication chip from the battery erases the SRAM memory, rendering the chip useless.
Battery authentication is based on a 'challenge/response' protocol between the microcontroller in the portable end-product and the CrytpoAuthentication IC in the battery. In order to speed system design, Atmel provides complete ARM- and AVR-compatible source code libraries that implement all necessary cryptographic modules for performing the host-side authentication capability. The AT88SA100S requires only a single GPIO pin on the host processor and only three wires on the connector to the battery, plus a standard bypass capacitor.
