摘要: 信任协商中的隐私保护方案大多建立在复杂的零知识协议基础上且很多需要配对运算,因此效率不高。针对这一问题,利用环签名的思想提出了一种协商证书匿名方案,在建立证书子集匿名性的形式化模型基础上利用离散对数的困难性构造环签名方案对协商证书进行保护。跟张明武等人的方案(张明武,杨波,祝胜林,等.保护协商证书隐私的策略签名方案. 电子与信息学报,2009,31(1):224-227)和LIU等人的方案(LIU BAILING, LU HONGWEI, ZHAO YIZHU. An efficient automated trust negotiation framework supporting adaptive policies. Proceedings of the Second International Workshop on Education Technology and Computer Science. Washington, DC: IEEE Computer Society, 2010:96-99)相比,所提方案具有更高的效率。

Abstract: At present, most of the privacy protection schemes are based on sophisticate zero-knowledge protocol or bilinear mapping computation, so their efficiency is low. In order to address this problem, an anonymous negotiation credentials scheme was proposed based on ring signature. On the foundation of anonymous credentials framework, an efficient discrete logarithm based ring signature scheme was constructed to protect the negotiation credentials, compared with two schemes proposed by ZHANG, et al. (ZHANG MING-WU, YANG BO, ZHU SHENG-LIN, et al. Policy-Based Signature Scheme for Credential Privacy Protecting in Trust Negotiation. Journal of Electronics & Information Technology, 2009(1): 224-227) and LIU, et al. (LIU BAILING, LU HONGWEI, ZHAO YIZHU. An efficient automated trust negotiation framework supporting adaptive policies. Proceedings of the Second International Workshop on Education Technology and Computer Science. Washington, DC: IEEE Computer Society, 2010: 96-99) the proposed scheme is more efficient.
