一个较快速的整数上的全同态加密方案
Faster fully homomorphic encryption scheme over integer
摘要
Abstract
In order to improve the efficiency of the fully homomorphic encryption scheme, based on partially approximate common divisor problem, a fully homomorphic encryption scheme over the integer is presented. Compared with the Dijk et al' s scheme, this scheme has these advantages of a smaller public key size and faster computation. Under this condition of allowing for a negligible probability of decryption error, this paper further reduces the complexity of the decryption algorithm, thus the given scheme is more efficient. Finally, it is proved that the scheme is semantically secure.关键词
