基于RSA和Paillier的同态云计算方案
Homomorphic Cloud Computing Scheme Based on RSA and Paillier
摘要
Abstract
In order to solve the ciphertext data calculation and the privacy protection of private cloud users issues in cloud computing environment,a homomorphic encryption scheme based on the homomorphic characteristics of RSA and Paillier is designed.Considering the fact that lacking an effective fully homomorphic encryption system at present,single homomorphic encryption system is used to construct somewhat homomorphic cloud computing scheme,which can satisfy multiplicative homomorphism and additive homomorphism and solve the ciphertext processing problem of the public cloud server successfully.It can achieve homomorphic calculation in the process of the ciphertext scale control,which has a large depth of the homomorphic calculation and completes the calculation for the data of floating-point types by an appropriate mapping.Simulation results show that compared to directly computing the plaintext,the proposed scheme needs more computing time,but it has higher correctness and security,and can meet various forms of computation requests in cloud computing environment.关键词
