Secure Multiparty Computation via Fully Homomorphic Encryption Scheme

With the rapid development and popularization of cloud computing, the security multiparty computation becomes a hot issue for the current research. This paper combs and analyzes the research of general security multiparty computation in cloud computing environment, and introduces the solution encryption schemes, including multi-key fully homomorphic encryption scheme based on Learning with errors and multi-key fully homomorphic attribute-based encryption scheme. This paper discusses the directions for future works in the end.
