Encrypted computation on a one instruction set architecture

As cloud computation becomes mainstream, the need to ensure the privacy of the data entrusted to third parties keeps raising. But the actual computation inside cloud microprocessors remains unencrypted. Thus, the opportunity of leakage is theoretically possible. Therefore, to address the challenge of protecting the computation inside the microprocessor, we introduce novel general purpose architecture for secure data processing. This new design utilizes single instruction architecture and provides native processing of the encrypted data at the architecture level. The security of the solution is assured by a variance of Paillier's Homomorphic encryption scheme, used to encrypt data when given as input manually and when retrieved from a memory location. So, here we use Paillier scheme (in homomorphic encryption) to work with One Instruction Set Computer (OISC).
