摘要:

针对无线移动网络漫游认证中的隐私保护需求,提出了新的匿名漫游认证方案。引入在线离线签名技术,并巧妙结合聚合验证方法,设计了一个无证书聚合签名方案。与相关方案相比,该签名方案降低了签名和验证过程的计算开销,提高了通信效率。继而,基于该签名方案,提出了一种新型高效的匿名漫游认证方案,简化了传统的三方漫游认证模型。理论分析结果表明,该方案安全、有效,特别适用于大规模无线移动网络。

Abstract:

To solve the privacy-preserving problem during the roaming authentication of wireless mobile networks, a novel roaming authentication scheme with anonymity was presented. An efficient certificateless aggregate signature scheme was first constructed, by introducing the online/offline signature and combining the aggregate signature. Com-pared with the related schemes, the proposed scheme has higher efficiency in computations of both signature and verifi-cation, and also improves the efficiency in communications. Furthermore, based on the proposed signature scheme, a novel roaming authentication scheme with anonymity was presented, in which it simplified the traditional three-party au-thentication model. The theoretical analysis shows that this scheme is secure and effective, and thus it is especially suit-able for large-scale wireless mobile networks.
