Design and implementation of hardware-based dynamic instruction set randomization framework

Abstract

All the existing ISR methods have some defects including stripping data from code segment is hard to accomplish,static ISR has fixed key and pseudo-random key is not secure.To introduce ISR technology into the se-curity protection of kernel layer and application layer,hardware-based dynamic instruction set randomization framework (HDISR) was designed and implemented,in which program code was encrypted at loading time.Kernel encryption uses kernel key and applications encryption uses a different user key per process.The experimental re-sults show that HDISR can degrade code injection attack to Denial of Service attack with less than 2.57% additional hardware and 0.31s startup delay of each megabyte code encryption.
