摘要
可验证加密签名方案可用于构建电子商务中优化的公平交换协议。通过对国内外可验证加密签名方案的研究状况进行分析,指出在当前的研究中存在的一些问题,如效率和安全的结合问题、隐私保护等,并通过对Li等人的可验证加密签名进行伪造攻击,说明可验证加密签名方案应满足强不可伪造性,最后,讨论了可验证加密签名的研究中需要解决的一些问题和未来的研究趋势。
The verifiably encrypted signature schemes can be used to construct optimistic fair exchange protocols.By analyzing the research advance of verifiably encrypted signature schemes,some problems such as the combination of efficiency with security and the privacy protection in the research of verifiably encrypted signature scheme are pointed out.By demonstrating a forgery attack to Li et al.’s verifiably encrypted signature scheme,it is found that a verifiably encrypted signature scheme should has the propriety of strong unforgerity.At last,some problems have to be solved in the research of verifiably encrypted signature schemes and the research in the future are discussed.
