Postdoctoral: Experiments in Security and Quality of Service in Mobile Systems

EIA-0103676 Bhargava，Bharat。普渡大学CISE实验计算机科学博士后研究员：移动的系统安全和服务质量实验地震、恐怖袭击或战争等紧急情况后的灾难恢复可能依赖于移动的通信系统。 安全性和服务质量（QoS）至关重要。 在移动的系统中提供安全性和QoS是一个难题，因为网络和其它资源的可用性可能随着移动的主机故障、移动或受到有意或无意的攻击而改变。 研究一种技术，以实现容错的移动的节点认证的有效方法，提出了博士后研究助理。 这种技术将消除单点故障，分布负载，增强可伸缩性和生存能力，并使故障对用户透明。 一系列的实验计划，将评估这种技术下的各种变量，并导致新的认证和密钥管理技术的发展。 该助理将1）确定QoS启用网络中上游域和入口路由器之间的认证指南，2）评估各种安全组通信和访问控制技术在无线通信中的适用性，以及3）探索将安全性视为QoS参数时的适应性要求。

EIA-0103676Bhargava, Bharat.Purdue UniversityCISE Postdoctoral Associates in Experimental Computer Science: Experiments in Security and Quality of Service in Mobile SystemsDisaster recovery after an emergency such as an earthquake, terrorist attack, or war may depend on mobile systems for communications. Security and Quality of Service (QoS) are of utmost importance. Providing security and QoS is a difficult problem in mobile systems because the availability of network and other resources may change as the mobile host fails, moves, or comes under intentional or unintentional attack. Research on a technique to achieve fault-tolerant mobile node authentication in an efficient way is proposed for a postdoctoral research associate. Such a technique would eliminate single points of failure, distribute loading, and enhance scalability and survivability, and make failures transparent to users. A series of experiments are planned that will evaluate this technique under a variety of variables and lead to the development of new authentication and key management techniques. The associate will 1) identify guidelines for authentication between an upstream domain and an ingress router in a QoS enabled network, 2) evaluate various secure group communication and access control techniques for suitability in wireless communications, and 3) explore adaptability requirements when considering security as a QoS parameter.
