Anonymous credentials scheme based on ring signature for trust negotiation
Jianting Yuan · Journal of Computer Applications · 2011
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.
