摘要 通过适当地选择参数改进了推广的Paillier(G-Paillier)加密体制,减少运算量,提高了加密体制的效率;证明了改进后加密体制的安全性(单向性、语意安全性)与G-Paillier加密体制的安全性是等价的。 The efficiency of the generalized Paillier (G-Paillier) encryption scheme is improved by choosing proper parameters. The efficiency of the improved G-Paillier scheme and the original G-Paillier scheme is compared. The security (one-wayness security, semantic security) equivalence of the improved encryption scheme and the G-Paillier encryption scheme is verified.
