摘要
随着云计算的快速发展,与云邮件系统相关的安全问题越来越受到人们的关注。传统公钥加密技术虽然可以满足云邮件系统的安全性需求,但是在易用性方面却存在严重不足。通过分析传统加密技术存在的不足,探讨前沿的代理重加密和可搜索公钥加密技术在解决云邮件系统的安全性与易用性方面的优势与存在的科学问题。
Along with the rapid development of cloud computing system, the security problems of cloud mail system has attracted many attentions. These problems can be solved by the traditional public-key encryption techniques, but they make the resulted cloud email system inconvenient for users. This paper analyzes the limitations of the tradition encryption techniques, introduces the advantages of some advanced encryption techniques, like proxy re-encryption and searchable public key encryption, and discusses the still existing problems of these techniques.
