An electronic online bidding auction protocol with both security and efficiency

In this paper, a new electronic auction scheme is proposed, which not only satisfies the requirement for the electronic auction properties of anonymity, security, privacy, atomicity and low overhead cost but also adds the properties of the non-repudiation, untraceability, auditability, one-time registration and unlinkability. Furthermore, we improve the operational scheme of the proposed electronic auction to meet its security and efficiency. Therefore, the proposed scheme is suitable for implementation.
