“…Pure soft-ware solutions itself cannot counter all attacks, therefore, enforcing security in processor design has drawn more and more attention. Currently many proposed works focus on encryption and authentication of hardware memory in singlecore systems (Gassend, Suh, Clarke, Dijk, & Devadas, 2003;Lee, Kwan, McGregor, Dwoskin, & Wang, 2005;Shi, Lee, Ghosh, Lu, & Boldyreva, 2005; Yan, Rogers, Englender, Solihin, & Prvulovic, 2006; Yang, Zhang, & Gao, 2003). They usually assume the processor core as a safe and secure unit.…”
