Abstract

Abstract:

Cloud computing as an emerging computing model can provide a variety of resources and services for public key encryption system. Cloud computing platform can provide independent software developers and developers to provide computing power, storage space and other aspects of support. This paper presents an outsourced decryption scheme for the El-Gamal encryption system, which uses the cloud platform to provide users with high-performance hardware computing power to help users improve the encryption efficiency and reduce the encryption costs. The scheme in the encryption process to introduce outsourcing encryption technology, can effectively guarantee the user data security. On the basis of the program, this paper designs a cloud encryption system to achieve the verification of the program. The result of the experiment shows that the program can help users to improve decryption efficiency under the premise of safety of user’s data.

Key words: cloud computing, secure outsourcing, cloud decryption, data safety
