WebSide-channel attacks (SCAs) are known as the prominent vulnerabilities of the secure systems. In this paper, the sensitivity of the FPGA designs against the timing attack are analyzed and then, a dynamic technique is proposed to mitigate the possibility of timing side-channel attacks. The proposed technique decreases the dependency of the circuit … WebSep 30, 2024 · The achievable resolution for timing depends heavily on the system and the attacker power. For example, when the normal operating system wants to attack an SGX enclave, the state of the art is a resolution of a single instruction. (I don't remember seeing a similar productized software for Arm TrustZone but it's likely just as feasible.)
