BSEA: A Blind Sealed-Bid E-Auction Scheme for E-Commerce Applications

Blog Article

Due to an increase in the number of internet users, electronic commerce has grown significantly during the last decade.Electronic auction (e-auction) is one of the famous e-commerce applications.Even so, security and robustness of e-auction schemes still remain a challenge.Requirements like anonymity and privacy of the b i d value are under threat from the attackers.

Any auction protocol must not leak the anonymity and the read more privacy of the b i d value of an honest Bidder.Keeping these requirements in mind, we have firstly proposed a controlled traceable blind signature scheme (CTBSS) because e-auction schemes should be able to trace the Bidders.Using CTBSS, a blind sealed-bid electronic auction scheme is proposed (BSEA).We have incorporated the notion of blind signature to e-auction schemes.

Moreover, both the schemes are based upon elliptic curve cryptography (ECC), which provides a similar level of security with a comparatively smaller key size than the discrete logarithm problem (DLP) based e-auction protocols.The analysis shows that BSEA fulfills all the requirements natio celebrate eyeshadow palette of e-auction protocol, and the total computation overhead is lower than the existing schemes.
