Research on the method of data privacy protection in cloud computing

Nanjing University of Posts and telecommunications Su Hong

Aiming at the distributed characteristics of cloud computing, this paper uses secret sharing strategy to establish a distributed encryption scheme. At the same time, in order to manage the multiple identities of cloud users uniformly, the identity-based public encryption Algorithm (IBE) is adopted and the secret sharing strategy is combined in IBE. This scheme is mainly aimed at untrusted cloud computing service providers, so the corresponding threshold strategy is used to reduce the data leakage threat from a single untrusted service provider, and the data provider will authorize the privacy data such as their identity information. After proposing the detailed steps of the scheme, this paper analyzes the two aspects of correctness and security, and further utilizes the key steps of the MIRACL Cipher database simulation scheme, and statistics the corresponding time consumption, which proves that the scheme has certain feasibility.
