A Secure Multi-Party Computing System Based on SGX Technology for Trusted Data Circulation

The security of data circulation is the core technology of data fusion and sharing service. The paper proposes multi-party circulation mechanism of the trusted data using to MPI communication. In order to achieve the trusted computing, this study proposes the computing service platform based on SMPC, which encapsulates the operation of sensitive data such as encryption key, password, user data, and etc.by trusted hardware using the security extension of Intel SGX. Meanwhile, aiming at these problems of semantic security and efficient processing ability, we chooses ElGamal homomorphic encryption system. In additional, SGX is extended to the remote authentication mechanism. System can support the deployment of hybrid cloud mode. Thus, the data security circulation can be satisfied. Compared to other methods, it has the advantage of model security and efficient communication.
