Abstract

Online auctions are inherently insecure and there exist many opportunities for participants to cheat. Cryptographic protocols can be applied to help alleviate some of these problems. However, different auction types have differing security requirements. This makes it difficult to construct schemes to prevent all possible forms of dubious behaviour. This paper presents a survey of cryptographic schemes that have been proposed for conducting private and secure auctions. The major auction types are investigated and their privacy and security requirements contrasted. We provide a uniform analysis of each auction scheme's functional components and analyse the efficiency of the security mechanisms. The paper's motivation is to give an all-encompassing overview of auction privacy and security, which has not been documented elsewhere. This paper supports supplementary research by the author into online auction fraud and security issues. We show that most schemes are currently not practical and there are conflicting perspectives regarding security requirements. Avenues for future research are proposed with regard to the present lacking state of commercial online auction security.
