Abstract :

Due to privacy leakage of sensitive data, the conventional encryption systems are not completely secure from an intermediary service like cloud servers. The homomorphic encryption is a special kind of encryption mechanism that can resolve the security and privacy issues. Unlike the public key encryption, this has three security procedures, i.e., key generation, encryption and decryption. In this project, design and implementation of high secure VLSI based MM-fully homomorphic encryption is done. This system will provide better security and resource efficiency compared to existing standards. fully homomorphic encryption and decryption technique guarantee both privacy and integrity. The main intent is to increase the speed of operation. Initially, input bits and key is given to S-Box. Next, bits are substituted using S-Box. After shifting operation is performed to the substituted bits. Now these bits are encrypted using MM homomorphic encryption. Hence MM homomorphic encryption better se
