ABSTRACT:
Within a communication device which utilizes digital encryption, volatile and non-volatile memory devices are used for the storage of encryption keys in unencrypted and encrypted form, respectively. A power sensing circuit, in conjunction with tamper detection circuitry, is used to help ensure the active erasure of keys from the volatile memory in the event of a non-secure operating condition.
