The enormous amount of access requests triggered by events such as a questionnaire on TV programs can be expected to occur in a short period of time. In such a case, since the server may gets unstable or incapacitated, it is expected that users cannot access on the server. To solve the problem, we have developed a congestion control system by suspending the users' requests temporarily. However, malicious users who have no intention to follow the predetermined protocol can easily connect the server, since the developed system possesses no authentication function. As a result, the developed congestion control system cannot work well. In this paper, we therefore propose an unauthorized illegal access rejection method for the developed system. By using the decryption-key for authentication information encrypted by the Time-Release Encryption, the proposed method can verify whether the user is authorized or not. Furthermore, the proposed certification method can be implemented on devices that have low computational ability such as cellular phones, since the proposed certification method requires low computational load. |
