Abstract

See full text

Embodiments of the invention create an underlying infrastructure in a flash memory device (e.g., a serial peripheral interface (SPI) flash memory device) such that it may be protected against user attacks—e.g., replacing the SPI flash memory device or a man-in-the-middle (MITM) attack to modify the SPI flash memory contents on the fly. In the prior art, monotonic counters cannot be stored in SPI flash memory devices because said devices do not provide replay protection for the counters. A user may also remove the flash memory device and reprogram it. Host platforms alone cannot protect against such hardware attacks.
