The wide use of wireless data services leads to sensitive and confidential information delivered over wireless links. With e-crimes resulting from such information being compromised to unauthorized parties at an all time high, the ?all wireless? vision can truly materialize only if the security of wireless information transfer can be guaranteed. Conventional approaches to information security are designed for wired networks with assumptions that lead to a disassociation from the physical medium in which communication takes place, and provide guarantees against adversaries that are computationally limited. This project provides a new approach for wireless networks to deliver provable and unconditional security. This research designs wireless networks with a secure foundation guaranteeing reliable and secure delivery of information. In doing so, the investigators account for untapped and rich resources provided by wireless systems naturally, including sources with correlated observations or application content, channels that provide spatial and temporal diversity, network nodes that are helpers or relays providing interaction, and broadcast and bi-directional nature of the medium enabling communication with feedback. The project calls for a network design paradigm that has security in its foundation and provides enlightened system design principles and protocols that are optimized to jointly exploit these resources. Some examples of this, which form the intellectual backbone of this project, include the optimal use of correlated sources and broadcast channels, the role of multinode interaction, the opportunistic use of potentially untrusted relay nodes, the creative use of feedback channels, in order to render intelligent and computationally unlimited (passive and active) adversaries ineffective. An extended goal is to integrate the resulting design principles for unconditional security with cryptographic approaches towards exploiting synergies between the two.

无线数据服务的广泛使用导致通过无线链路传递敏感和机密信息。由于此类信息被未经授权的各方泄露而导致的电子犯罪数量空前高涨，“全无线”技术已成为人们关注的焦点。只有保证无线信息传输的安全，愿景才能真正实现。传统的信息安全方法是为有线网络设计的，其假设导致与进行通信的物理介质分离，并提供针对计算能力有限的对手的保证。该项目为无线网络提供了一种新的方法来提供可证明的、无条件的安全性。这项研究设计了具有安全基础的无线网络，保证信息的可靠和安全传递。 在此过程中，研究人员考虑了无线系统自然提供的未开发且丰富的资源，包括具有相关观测或应用内容的源、提供空间和时间多样性的通道、作为提供交互的帮助者或中继的网络节点以及广播和双向网络。媒介的方向性使得沟通与反馈成为可能。该项目需要一种以安全为基础的网络设计范式，并提供经过优化以共同利用这些资源的开明系统设计原则和协议。这方面的一些例子构成了该项目的知识支柱，包括相关源和广播通道的最佳使用、多节点交互的作用、潜在不受信任的中继节点的机会主义使用、反馈通道的创造性使用，以便使智能且计算能力不受限制（被动和主动）的对手无效。一个扩展的目标是将最终的无条件安全设计原则与加密方法相结合，以利用两者之间的协同作用。
