Wireless networks play a key role in national critical information infrastructure. Mainly due to lack of a protected physical boundary, wireless communications are inherently less secure than its wired counterpart. Privacy has been ranked as the top security concern of wireless users. Inadequate privacy protection can result in significant network information retrieval that enables the adversaries to perform destructive denial-of-service (DoS) attacks, or even paralyze the entire wireless networks. While confidentiality of the message can be ensured through content encryption, it is much more challenging to provide privacy service for wireless networks. In fact, privacy is one of the most notable challenges looming on the horizon that threatens successful deployment of WSN. In this research, we propose to design efficient cryptographic algorithms and network security protocols that can achieve privacy-preserving communications for both MANET and WSN. More specifically, we plan to: (i) Develop efficient cryptographic algorithms that can achieve unconditional privacy-preserving communications even in the presence of local eavesdropper while reconciling communication accountability; (ii) Develop efficient anonymous authentication schemes and protocols for secure user access control and anonymous routing in MANET and WSN. That is, while each user is being authenticated, the user's real identity and location will remain secret for adversaries. (iii) Establish a scientific foundation for theoretical characterization and quantitative measurement of privacy in secure network communications. Our research is expected to have a significant impact on personal privacy, national critical information security as well as homeland security.

无线网络在国家关键信息基础设施中发挥着关键作用。主要由于缺乏受保护的物理边界，无线通信本质上不如有线通信安全。隐私已被列为无线用户最关心的安全问题。不充分的隐私保护会导致大量的网络信息检索，使对手能够执行破坏性的拒绝服务（DoS）攻击，甚至使整个无线网络瘫痪。虽然通过内容加密可以确保消息的机密性，但为无线网络提供隐私服务更具挑战性。事实上，隐私是威胁无线传感器网络成功部署的最显着挑战之一。在这项研究中，我们建议设计有效的密码算法和网络安全协议，可以实现隐私保护的移动自组网和无线传感器网络的通信。更具体地说，我们计划：（一）开发高效的加密算法，可以实现无条件的隐私保护的通信，即使在存在本地窃听者，同时协调通信问责制;（二）开发高效的匿名认证方案和协议，安全的用户访问控制和匿名路由的MANET和WSN。也就是说，当每个用户都被认证时，用户的真实的身份和位置将对对手保持秘密。(iii)为安全网络通信中隐私的理论表征和定量测量奠定科学基础。我们的研究预计将对个人隐私，国家关键信息安全以及国土安全产生重大影响。
