Abstract

In the conventional encryption method, the encryption effect is mainly improved by expanding the encryption space. But the encryption randomness is large. The encryption security is reduced. Therefore, the subject of secure encryption method of privacy set intersection based on a homomorphic encryption algorithm is designed. By using the homomorphic encryption algorithm, the encryption privacy set intersection protocol is designed to encrypt the random elements of privacy combined with communication. The privacy set intersection encryption extreme difference protocol is established to prevent communication data from being stolen and ensure the security encryption effect of privacy information. By the way of comparative experiments, it is verified that the encryption method has high security and can be applied to real life.
