TWC: Small: Towards Stealth Networks: Fundamental Limits and Algorithms for Stealth Communications

通信网络的广泛发展深刻地改变了我们的社会，导致生产力和效率的显著提高。然而，这种增加的连接性的好处今天也被恶意个人可以干扰或篡改敏感数据和信息的容易性所抵消。因此，在过去的十年中，人们越来越关注通信的隐私、保密和完整性问题。在许多情况下，通信网络中的用户现在可能希望在不被其他人检测到的情况下进行通信，以保持隐私、避免攻击或逃避监视网络的监管实体的注意。该项目采取了独特的方法来奠定一个全面的框架的基础，使基本的信息理论的限制和隐形通信的显式低复杂度算法的发展的分析。该项目调查两个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，以便系统地分析各种信道模型上的隐形通信;这包括具有和不具有密钥的架构，以及有线和无线网络，其中隐私和不可检测性发挥着核心作用。在第二项任务中，研究人员将从用于隐形通信的错误控制代码中设计低复杂度算法，并将在实验原型上进行测试。与该项目有关的其他活动包括以各种形式传播研究成果和指导学生。所提出的研究有可能使可证明的隐形通信系统的实施取得进展，并导致新的成本效益高的隐形通信系统的一代技术。

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.
