Reducing Data Decryption Cost by Broadcast Encryption and Account Assignment for Web Applications

摘要：

Protection of user privacy is an important issue of Web applications. Data encryption presents a possible resolution for improving the security level of Web applications. In this paper, we propose a novel mechanism using broadcasi encryption and account assignment methods to reduce the decryption cost of Web applications. A notable feature of our mechanism is that the additional function of the application server is not necessary. Moreover, it is easy to apply this method to existing servers to improve their security level. We also show some experimental results to demonstrate the feasibility of our methods.
