Extended abstract: An embedded flash memory vault for software Trojan protection

Embedded system protection from software corruption

“…The main focus of this paper is a novel vault architecture which operates in tandem with the memory subsystem and protects it from instruction code corruption [2]. The proposed hardware vault architecture consists of a shadow RAM or shadow Cache, flash memory, and a vault manager.…”

Preventing integrated circuit piracy using reconfigurable logic barriers

“…Then in [69], a one-time pad is used in combination with a CRC-based integrity checker to secure the memory. Finally, [73], utilizes a shadow memory that is initialized by a trusted person and then cannot be altered. Calls are checked with the shadow memory and differences signal an attack.…”
