| Abstract: |
| 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. |
