Abstract
Provided is a system for execution protection using data colouring. The system includes a central processing unit (CPU), a system memory (SM) and a secure agent component (SAC). The SAC monitors memory access instructions occurring between the CPU and SM. The SAC comprises a colour memory (CM) storing a colour tag for each memory address of the system memory (SM). The SAC stores instructions at a destination address, and copies the colour tag stored at the instruction address in the colour memory to the destination address in the colour memory (CM) while storing data. The SAC loads instruction at a retrieval address, and compares the colour tag stored at the retrieval address and the colour tag at the load instruction in the colour memory (CM). A dysfunction is detected if colour tags are different. Other embodiments disclosed.
