On the basis of analyzing the basic process and research meaning of the online bidding system, a new undeniable digital signature scheme based on the online bidding system is presented, which enables an authentication system to validate a user's identity without exposing the user's secretinformation. This scheme contains some methods such as encryption of bidding information with rijndael arithmetic, digital digest of bidding information with SHA arithmetic, encryption of digital digest with RSA arithmetic and so on. Key techniques to apply-rijndael arithmetic, RSA arithmetic and systematic security of this system are analysed. The experimental results illustrate the effectiveness of the proposed method.
