LIBMPK: SOFTWARE ABSTRACTION FOR INTEL MEMORY PROTECTION KEYS (INTEL MPK)

NettetThe key idea is to combine protection keys (MPKs), a feature recently added to x86 that allows protection domain switches in userspace, with binary inspection to prevent circumvention. Nettetattackers from tricking MPK by corrupting the protections keys in the memory, and (3) inter-thread key synchronization to ensure the semantics of mprotect() with MPK. First, libmpk provides virtual protection keys to applica-tions to hide real hardware keys from them. This design avoids the protection-key-use-after-free problem by schedul-
