Towards Privacy Preservation in Strategy-Proof Spectrum Auction Mechanisms for Noncooperative Wireless Networks

Fan Wu, Qianyi Huang, Yixin Tao, Guihai Chen
2015 IEEE/ACM Transactions on Networking  
PRIDE guarantees -anonymity for both single-and multiple-channel auctions. Furthermore, we enhance PRIDE to provide -diversity, which is an even stronger privacy protection than -anonymity.  ...  However, none of these approaches protects bidders' privacy. In this paper, we present PRIDE, which is a PRIvacy-preserving anD stratEgy-proof spectrum auction mechanism.  ...  Her research interests lie in privacy preservation and resource management in wireless networks.
