项目摘要

The widespread development of communication networks has profoundly transformed our society, resulting in a significant increase in productivity and efficiency. However, the benefits of this increased connectivity are today also counterbalanced by the ease with which malicious individuals can interfere or tamper with sensitive data and information. The past decade has thus witnessed a growing concern for the issues of privacy, confidentiality, and integrity of communications. In many instances, the users in a communication network may now wish to communicate without being detected by others, to maintain privacy, avoid attacks, or escape the attention of regulatory entities monitoring the network. This project takes a distinctive approach to lay the foundation of a comprehensive framework, enabling both the analysis of the fundamental information-theoretic limits and the development of explicit low-complexity algorithms for stealth communication.The project investigates two interrelated research tasks. In the first task, the researchers will develop information-theoretic tools enabling the systematic analysis of stealth communications over a wide range of channel models; this includes architectures with and without secret keys, as well as wired and wireless networks, in which privacy and un-detectability play a central role. In the second task, the researchers will design low-complexity algorithms from error-control codes for stealth communication, which will be tested on experimental prototypes. Additional activities related to the project include, dissemination of research results in various forms and mentoring of students. The proposed research has the potential to enable advances in the implementation of provably stealth communication systems and lead to novel cost-effective techniques for the the generation of stealth communication system.

通信网络的广泛发展已深刻地改变了我们的社会，从而显着提高了生产力和效率。但是，如今，这种提高连通性的好处也与恶意个人可以干扰或篡改敏感数据和信息的轻松相抵消。因此，过去十年来，人们对隐私，机密性和通讯的完整性问题越来越关注。在许多情况下，通信网络中的用户现在可能希望在不被他人检测到的情况下进行通信，以维持隐私，避免攻击或逃避监控网络的监管实体的关注。该项目采用独特的方法来奠定全面框架的基础，从而对基本信息理论限制进行分析，并为隐身通信的显式低复杂算法的发展开发。该项目研究了两项相互关联的研究任务。在第一项任务中，研究人员将开发信息理论工具，从而实现广泛的渠道模型中隐身通信的系统分析；这包括带有和无秘密钥匙的体系结构，以及有线和无线网络，其中隐私和非可检测性起着核心作用。在第二项任务中，研究人员将设计低复杂性算法，该算法是从错误控制代码中的隐形通信设计，该算法将在实验原型上进行测试。与该项目相关的其他活动包括，以各种形式进行研究结果和学生的指导。拟议的研究有可能在实施可证明的隐形通信系统实施方面进步，并为隐身通信系统的产生提供新颖的成本效益技术。
