AES-128 EEPROM
The Atmel AES132 is an AES encrypted EEPROM that can store up to 32Kb of data. Specifically, it uses AES with a 128 bit key in CCM mode.
There currently is not a linux driver that uses this hardware, however you can use the Atmel AES132 AVR software. As with the other crypto chips, once you run the lock command, this is an irreversible operation.
