摘要：An anonymous fingerprinting scheme was presented by Domingo, which can identify the redistributors without the help of registration authority. However, this scheme on average requires N/2 exponential operations when the merchant identifies the redistributors, where N is the number of public keys in the directory. Chanjoo Chung proposed a more efficient scheme than Domingo’s, but there is a fatal weakness in the proposed registration protocol of his scheme. This weakness causes that any impersonator can personate an honest buyer with the probability of 1/2. In this paper, we give an efficient scheme that requires only one exponential operation, which improves the whole scheme’s efficiency. Security analysis is also given at last.
