摘要/Abstract

摘要：

云计算作为一种新兴计算模式可以为公钥加密体制提供多种资源及服务。云计算平台可以为独立软件开发人员与开发商提供计算能力、存储空间等方面的支持。文章提出一种针对El-Gamal加密体制的外包解密方案,方案使用云平台向用户提供高性能硬件的计算能力,帮助用户提高加密效率,降低用户加密成本。方案在加密过程中引入外包加密技术,可以有效保证用户数据安全。在该方案的基础上,文章设计了一个云密码系统实现了对文中方案的验证。实验结果表明,文中系统能在保证用户数据安全的前提下帮助用户提高解密效率。

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
