An Anonymous and Secure Continuous Double Auction Scheme

Abstract

A Continuous Double Auction (CDA) allows many buyers and sellers to continuously submit bids for the purchase and sale of a commodity (e.g., online share trading). Protocols protecting privacy in this type of powerful market mechanism are essential. However, until recently the security of CDAs has been given limited coverage. This paper describes a new scheme for conducting an anonymous and secure CDA. We show that any existing secure group signature scheme can be used to implement a CDA which has the following characteristics: unforgeability, anonymity, unlinkability, exculpability, coalitionresistance, verifiability, robustness and traceability. Furthermore, bidders can be added to and removed from the auction without affecting the process of the auction. Our scheme is more flexible than the only existing secure CDA scheme, which in contrast provides only a limited subset of these characteristics.

A Privacy Protection Scheme of Microgrid Direct Electricity Transaction Based on Consortium Blockchain and Continuous Double Auction

“…For users, no other user information can be forged to generate a pseudonym certificate. Since the pseudo-names of other consumer information are generated, it is necessary to satisfy the Formula (11) and (12). However, the user cannot obtain the RM private key to satisfy the above formula, so the user cannot generate the pseudonym certificate through the verification of the MM.…”

“…However, its marketing manager has a pseudonym and a real identity correspondence, which is likely to cause the bidder's privacy to leak. Based on the literature [11], a new scheme based on group signature CDA was proposed in paper [12], which not only enables secure anonymity but also adds and removes bidders in bids without affecting the auction process.The electronic auction scheme based on group signature and partial blind signature was proposed in paper [13], which reduced the dependence on trusted third parties. However, [12], [13] all have the problem that group administrators have the supreme right of identity tracking, and it is possible that administrators abuse their power to expose users' privacy [14].…”

The British electronic auction scheme based on the revocable ring signature proposed in [15] can achieve conditional privacy but requires multiple repeated bilinear operations to achieve traceability [16].…”

Security, anonymity and trust in electronic auctions

“…We are also applying this concept to a form of auction referred to as a continuous double auction, where there aremany buyers and many sellers (e.g., a share market) [11].…”
