中文摘要
交换秘密信息、保证隐私和提供真实性的能力构成了当今信息社会信任的基础。与有线通信相比,无线介质的使用由于其广播性质而非常容易被窃听。为了克服这一挑战,开发无线传播介质的内在属性势在必行。利用这些特性的一个关键观察是,广播性质产生了截然不同的效果:它使来自特定合法发送器的机密信息容易受到恶意拦截,但同时,它使其他合法合作伙伴能够通过干扰阻碍窃听接收器的能力。然而,干扰对窃听接收者和合法接收者的并发影响还没有得到彻底的调查。这就需要研究如何仔细设计网络干扰,以充分利用其无线保密的潜力。该项目旨在开发协作干扰工程策略,以协调多个合法合作伙伴的发送和接收,以产生用于无线保密保护的理想的聚合干扰。新的技术将被设计来阻碍窃听者的能力,而对合法的接收者几乎没有影响。具体地说,本研究的目的是:(1)刻画协作干扰工程对控制注入到无线网络中的聚合干扰的基本极限;(2)为协作干扰工程技术的设计建立理论基础;(3)评估协作干扰工程技术的性能及其对网络保密的好处。这项研究结合了通信、信息、代数几何和随机几何的各种理论,为设计具有新水平的保密保护的无线网络奠定了基础。
英文摘要
The ability to exchange secret information, to guarantee privacy, and to provide authenticity forms the basis for trust in today's information society. In contrast to communications via wires, the use of a wireless medium is highly susceptible to eavesdropping due to its broadcast nature. To overcome this challenge, it is imperative to exploit the intrinsic properties of the wireless propagation medium. A key observation for exploiting such properties is that the broadcast nature generates contrasting effects: it makes the secrecy information from a certain legitimate transmitter vulnerable to malicious interception, but at the same time, it enables other legitimate partners to impede the capability of eavesdropping receivers via interference. However, the concurrent effect of interference on both eavesdropping receivers and legitimate receivers has not been thoroughly investigated. This calls for research on carefully engineering the network interference to fully harness its potential for wireless secrecy. This project aims at developing cooperative interference engineering strategies that coordinate the transmission and reception of multiple legitimate partners to generate desirable aggregate interference for wireless secrecy protection. New techniques will be designed to impede the eavesdropper's capability while having little effect on the legitimate receivers. Specifically, this research aims to: (1) characterize the fundamental limit of cooperative interference engineering for controlling the aggregate interference injected into a wireless network; (2) set up a theoretical foundation for the design of cooperative interference engineering techniques; and (3) evaluate the performance of cooperative interference engineering techniques and their benefits to network secrecy. The proposed research combines various theories in communication, information, algebraic geometry, and stochastic geometry, serving as a foundation for the design of wireless networks with a new level of secrecy protection.
