Abstract

With the increasingly serious threat of privacy protect, the collaborative precision positioning cloud service urgently needs to be carried out homomorphic encryption protection for sensitive data. But the existing asymmetrical approaches are inefficient and are not practical for applications, while the symmetric approaches has low security. In this paper, based on the MORE and Enhanced MORE symmetric homomorphic encryption algorithms, we proposes a fully homomorphic encryption mechanism called DSFHE, with dynamic key generation, symmetric encryption and random encryption. Analysis and experimental results show that the proposed mechanism reduces the cipher-text storage overhead and execution time, which also can prevent the strong attacks.
