项目摘要
Proposal Title: CT-ISG: Collaborative Research: Key Generation from PhysicalLayer Characteristics in Wireless NetworksInstitution: University of ConnecticutAbstract Date: 08/05/08This project focuses on the development of a new class of secret key generation andrenewal algorithms for securing wireless networks by taking advantage of physicallayer characteristics. The basis of the approach is the identification of measurablequantities of the wireless channel between a pair of nodes that are highly correlatedexclusively between them (albeit not identical). Capitalizing on this correlation, theproject develops algorithms for obtaining a shared key under various adversarialmodels.This addresses a critical problem area as the broadcast nature of a wireless linkprovides a natural eavesdropping and intervention capability to an adversary and thus itfollows that securing a wireless link is essential to the security of any wireless network.This project undertakes the design, implementation, analysis and testing of severalprotocols and clarifies the relationship between the channel characteristics and thecryptographic protocols that use them. It also investigates the trade-offs betweencomputational and communication costs, and quantifies the level of security achievedby the key generation and renewal protocols assuming various adversarial models.The broader impact of the project is in the potential of making wireless communicationsmore secure while avoiding costs (both computational and organizational) ofcryptography. Given the increased wireless internetworking and the multitude ofwireless enabled devices presently carried by an average user, the security of thewireless link becomes one of the most critical aspects of securing computer systems.The reduction in the computation also will translate to a reduction in energy use,important to battery or alternative powered systems. Educationally, the project willpresent an attractive combination of aspects of signal processing, computer security,algorithms and cryptography and will offer a wealth of problems for student engagement
提案标题:CT-ISG:协作研究:从无线网络的物理层特征生成密钥机构:康涅狄格大学摘要日期:08/05/08本项目致力于开发一种新的密钥生成和更新算法,用于利用物理层特征保护无线网络。该方法的基础是识别一对节点之间的无线信道的可测量等量,这些节点之间高度相关(尽管不完全相同)。利用这种相关性,该项目开发了在各种攻击模式下获取共享密钥的算法。这解决了一个关键问题领域,因为无线链路的广播性质为攻击者提供了自然的窃听和干预能力,因此无线链路的安全对于任何无线网络的安全都是必不可少的。该项目承担了几种协议的设计、实现、分析和测试,并澄清了信道特征和使用它们的加密协议之间的关系。它还研究了计算和通信成本之间的权衡,并在假设各种对抗模型的情况下量化了密钥生成和更新协议所实现的安全级别。该项目的更广泛的影响在于使无线通信更安全的潜力,同时避免密码学的成本(计算和组织)。鉴于无线网络的增加和目前普通用户携带的大量支持无线的设备,无线链路的安全性成为确保计算机系统安全的最关键方面之一。计算的减少还将转化为能源消耗的减少,这对电池或替代电源系统非常重要。在教育方面,该项目将展示信号处理、计算机安全、算法和密码学方面的吸引人的组合,并将为学生参与提供丰富的问题
