The importance of the Internet for society is increasing. To ensure a functional Internet, its routers need to operate correctly. However, the need for router flexibility has led to the use of software-programmable network processors in routers, which exposes these systems to data plane attacks. Recently, hardware monitors have been introduced into network processors to verify the expected behavior...
Embedded systems require low overhead security approaches to ensure that they are protected from attacks. In this paper, we propose a hardware-based approach to secure the operation of an embedded processor instruction-by-instruction, where deviations from expected program behavior are detected within the execution of an instruction. These security-enabled embedded processors provide effective defenses...
