在IMS服务认证中集成基于身份的密码学

Integrating identity-based cryptography in IMS service authentication

Mohamed Abid, Songbo Song, Hassnaa Moustafa, Hossam Afifi

摘要:

IP多媒体子系统(IMS)是目前一个很有前途的研究领域。许多正在进行的工作有关的安全性和性能的就业介绍给研究界。虽然安全和数据隐私方面在国际监测系统的全球目标中非常重要,但迄今为止很少受到关注。多媒体业务的安全访问是基于IMS体系结构之上的SIP和HTTP摘要。该标准部署了AKA-MD5用于终端认证。第三代合作伙伴计划(3GPP)提供了通用自举架构(GBA)以在通过HTTP访问多媒体服务之前对订户进行认证。在本文中,我们提出了一个新的IMS服务认证方案,使用基于身份的密码(IBC)。这种新的方案将导致更好的性能时,有同时使用基于身份的批量验证的认证请求。分析了新协议的安全性,并对其密码操作进行了性能评估

英文摘要:

Nowadays, the IP Multimedia Subsystem (IMS) is a promising research field. Many ongoing works related to the security and the performances of its employment are presented to the research community. Although, the security and data privacy aspects are very important in the IMS global objectives, they observe little attention so far. Secure access to multimedia services is based on SIP and HTTP digest on top of IMS architecture. The standard deploys AKA-MD5 for the terminal authentication. The third Generation Partnership Project (3GPP) provided Generic Bootstrapping Architecture (GBA) to authenticate the subscriber before accessing multimedia services over HTTP. In this paper, we propose a new IMS Service Authentication scheme using Identity Based cryptography (IBC). This new scheme will lead to better performances when there are simultaneous authentication requests using Identity-based Batch Verification. We analyzed the security of our new protocol and we presented a performance evaluation of its cryptographic operations
