Research on encryption strategy in large data environment based on proxy re-encryption

Abstract

Human society has been experiencing an unprecedented revolution in the recent years' rapid development of information technology. In the open and distributed environment of large data, data encryption technology has become an important issue. In order to solve the security problem of big data storage, in this paper, we study the encryption algorithm based on big data, and we design a proxy re-encryption scheme by using the method of random number encryption. We propose the main steps of proxy re-encryption schemes, and we design the proxy re-encryption scheme of each part of the main encryption algorithm. In this scheme, we ensure the big server cannot get the clear text information. Finally, we use the JPBC function library and other techniques to program the proxy re-encryption scheme, which proves the availability and feasibility of the scheme. Then we put forward the network information security encryption solution in big data environment.
