Abstract
Systems and methods are provided for securing a self-securing device and information that is stored in memory within the device. The self-securing device comprising a processor unit and memory external to the processor unit. The processor unit contains a processor and processor unit memory. Upon initialization of the self-securing device, the processor unit determines whether a secure key is stored in the processor unit memory. If no secure key is stored, then the processor unit generates a secure key and stores it in the processor unit memory. The processor unit uses the secure key to decrypt information read from the memory external to the processor unit and to encrypt information to be stored in memory external to the processor unit.
