Collaborative Research: CT-T: Security and Survivability of Real-Time Systems with MANETs

基于移动自组织网络（mRTS）的实时系统在科学研究、医疗保健、灾难恢复、环境控制、军事和国土安全以及工业过程控制等领域具有潜在的应用前景。例如，这种系统可以为灾害和救援情况下的行动提供关键任务支持，例如最近在整个南亚发生的毁灭性海啸，整个通信基础设施被摧毁。本文从三个相互作用的方面对系统的安全性、生存性和实时性需求进行了研究：mRTS的安全性和实时性需求的规范和分析；约束感知生存通信技术，为mRTS提供可靠的无线通信；以及mRTS的安全性、容错实时性能和可生存无线通信的集成。该项目旨在开发：(a)通用mRTS模型和用于指定安全性和实时性要求的策略规范语言，(b)用于manet中约束感知容错拓扑控制的算法，(c)用于延迟敏感和延迟严格的实时应用的通道访问调度协议。本研究建立在先前工作的基础上，该工作开发了一个时间触发的消息触发的对象编程和规范框架，以及一个态势感知的分布式安全策略实施方案。这项研究的结果有望大大改善移动自组织网络的应用，如灾难救援，并将促进自组织网络与现有全球信息基础设施之间的互动。新的课程材料正在安全和可生存的实时系统中开发，结果在网络上自由传播。

Yau-Kim abstractCollaborative Research: CT-T: Security and Survivability of Real-time Systems with MANETsReal-time systems with mobile ad hoc networks (mRTS) have potential applications in many areas, including scientific research, healthcare, disaster recovery, environment control, military and homeland security, and industrial process control. For example, such systems can providemission critical support for operations in disaster and rescue situations, such as the recent devastating tsunamis throughout South Asia, where the entire communication infrastructure was destroyed. This research focuses on system requirements for security, survivability and real-time performance by focusing on three interacting aspects: specification and analysis of security and real-time requirements for mRTS; constraint-aware survivable communication techniques to provide reliable wireless communication in mRTS; and integration of security, fault-tolerant real-time performance, and survivable wireless communication for mRTS. The project seeks to develop: (a) a general mRTS model and a policy specification language for specifying security and real-time requirements, (b) algorithms for constraint-aware fault tolerant topology control in MANETs, (c) a channel access scheduling protocol for real-time applications that are delay-sensitive and delay-stringent. This research builds on prior work that developed a Time-triggered Message-triggered Object programming and specification framework, and a situation-aware distributed security policy enforcement scheme.The results of this research are expected to greatly improve mobile ad hoc network applicatons, such as disaster rescue and will foster interaction between ad-hoc networks and the existing global information infrastructure. New course materials are being developed in secure and survivable real-time systems, and results are freely disseminated on the web.
