Abstract:

Based on bilinear pairings and dynamic accumulators, a new ID-based linkable ring signature scheme (SLRS-BP) was presented. According to SLRS-BP, a fair e-cash protocol (EC-LR) with revocable anonymity was given. By virtue of constant-size signature of SLRS-BP and the spontaneity of ring signatures, the EC-LR will show good for the bank systems which have large numbers of dynamically changed users. In addition, EC-LR can avoid the member revocation problem of e-cash protocols based on group signatures.

Key words: linkable ring signature, bilinear pairings, dynamic accumulators, revocable anonymity, fair e-cash
