Abstract

Data security of small & medium-sized banks in transmission, storage and even calculation in cloud environment challenges traditional encryption technology. Nevertheless, homomorphic encryption technology could meet users' needs in data privacy and cloud computing resources simultaneously. Current homomorphic encryption schemes have limited plaintext space and thus limited application scenarios. Based on the homomorphic encryption scheme over integer proposed by Dijk et al., this paper proposes an enhanced scheme which expands the plaintext space from monobit range to a finite prime field, and verifies the correctness and efficiency of it, effectively promoting the practicability of homomorphic encryption.
