Control flow instructions in arm
WebMay 1, 2024 · Control flow integrity (CFI) is an important cornerstone for the security of ARM-based IoT devices, as it enforces the correct control flow of devices and defends against CRAs. However, coarse-grained CFI schemes suffer from security issues, like key leakage and coarse-grained protection, which allows attackers to bypass their defenses. Webinclude Pointer Authentication instructions: “a mechanism for enhanced security associated with pointer authentication”. It is very exciting to see the technology, refined and …
