The Homomorphic Encryption Scheme of Security Obfuscation

摘要：

　　In the cloud storage service, according to the data on the cloud computing safety protection problem, the paper presents secure obfuscating homomorphism encryption scheme.Constructing a point function obfuscation that based on perfectly one way probability hash function in scheme, construction depends on hash function and the computational difficulty problems, then use the computational difficulty problems, to realize the encrypted homomorphism function, also guarantee the function of the point function obfuscator at the same time, the scheme raises the security of the encrypted data.This paper provides the security proof of the scheme, shows that the scheme is feasible.
