Trusted tamper reactive secure storage

摘要

A cryptographic system includes a memory device and a processor. The memory device has at least two sections, including a first section and a second section. The processor is configured to determine a mode of operation, receive a signal, and selectively zeroize at least one section of the memory device based at least in part on the received signal and the determined mode of operation.

主权项

1. A cryptographic system comprising:
a memory device having at least two sections, including a first predetermined section and a second predetermined section; and a processor configured to determine a mode of operation among at least a first mode of operation and a second mode of operation, receive a signal, and selectively zeroize at least one of the first predetermined section and the second predetermined section of the memory device based at least in part on the received signal and the determined mode of operation, wherein the signal includes one of a first input signal corresponding to the first mode of operation and a second input signal corresponding to the second mode of operation, wherein the processor is programmed to zeroize the first predetermined section in response to receiving the first input signal and the second predetermined section in response to receiving the second input signal.
