摘要：Methods, devices, and systems for detecting return-oriented programming
(ROP) exploits are disclosed. A system includes a processor, a main memory, and a cachememory. A cache monitor develops an instruction loading profile by monitoring accessesto cached instructions found in the cache memory and misses to instructions notcurrently in the cache memory. A remedial action unit terminates execution of one ormore of the valid code sequences if the instruction loading profile is indicative ofexecution of an ROP exploit involving one or more valid code sequences. The instructionloading profile may be a hit/miss ratio derived from monitoring cache hits relative tocache misses. The ROP exploits may include code snippets that each include anexecutable instruction and a return instruction from valid code sequences.
