CIF: Small: Cooperative Interference Engineering for Network Secrecy

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。与经由有线的通信相反，无线介质的使用由于其广播性质而极易受到窃听。为了克服这一挑战，必须利用无线传播介质的固有特性。利用这些属性的一个关键观察是，广播性质产生对比效应：它使来自某个合法发射机的保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来阻止窃听接收机的能力。然而，窃听接收器和合法接收器上的干扰的并发效果还没有被彻底调查。这就要求研究仔细设计网络干扰，以充分利用其潜在的无线保密性。该项目旨在开发合作干扰工程策略，协调多个合法合作伙伴的发送和接收，以产生所需的聚合干扰，用于无线保密保护。新的技术将被设计成阻碍窃听者的能力，而对合法接收者几乎没有影响。具体而言，本研究的目的是：（1）表征的基本限制的合作干扰工程控制聚合干扰注入到无线网络;（2）建立一个理论基础的合作干扰工程技术的设计;（3）评估的合作干扰工程技术的性能和它们的好处，网络保密。拟议的研究结合了通信，信息，代数几何和随机几何的各种理论，作为一个新的保密保护水平的无线网络设计的基础。

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.
