A secure processor architecture forEncrypted computation on Untrusted ProgramsChristopher FletcherMIT van DijkRSA DevadasMIT paper considers encrypted computation where the user speci-fies encrypted inputs to an untrusted program, and the server com-putes on those encrypted inputs. To this end we propose a secureprocessor architecture , calledAscend, that guarantees privacy ofdata when arbitrary programs use the data running in a cloud-likeenvironment ( , an untrusted server running an untrusted soft-ware stack).
Ascend is marginally more complex than a conventional proces- sor, in the sense that Ascend must implement an ISA and also make sure that the work it does is sufficiently obfuscated.
