Secure Mobile Systems

在移动计算环境中，生存性和安全通信是必不可少的。我们建议进行一系列的实验，这些实验将导致新的无线通信认证和密钥管理技术的发展。我们研究了各种认证方案的实现对系统整体性能的影响。提出了一种高效实现移动节点容错认证的技术。我们计划在QoS启用的网络中确定上游域和diffserver入口路由器之间的认证指南。我们将以系统的方式进行科学实验，评估各种安全组通信和访问控制技术如何适应无线世界。我们将解决在移动环境下提供安全多媒体通信的问题，因为移动主机可用的资源（如CPU功率和网络带宽）非常有限。我们开发了一系列轻量级的视频加密算法，将视频压缩和视频加密一步走。这将导致一个适应性强的加密系统。

Survivability and secure communications are essential in a mobilecomputing environment. We propose to conduct a series of experimentsthat will lead to the development of new authentication and key managementtechniques for wireless communications. We study the implementation ofvarious authentication schemes on the overall system performance. Wepropose a technique to achieve fault-tolerant mobile node authenticationin an efficient way. We plan to identify guidelines for authenticationbetween an upstream domain and a DiffServ ingress router in a QoS enablednetwork. We will evaluate how various secure group communication andaccess control techniques fit into the wireless world by conducting scientific experiments in a systematic way. We will solve the problem of providing secure multimedia communication under mobile environments wherethe resources available to mobile hosts such as CPU power and networkbandwidth are very limited. We have developed a series of light-weightvideo encryption algorithms which encompass video compression and videoencryption in one step. This will lead towards an adaptableencryption system.
