Information-theoretic security is the science of safeguarding information across a communication network based on the use of concepts and techniques in information theory. It encompasses protection against eavesdropping, impersonation, and substitution attacks made by potential adversaries present in the network. Whereas eavesdropping and impersonation attacks (and solutions) are well studied, substitution attacks, in which the adversary replaces messages from a source by different valid messages from the same source, present new risks in an increasingly networked world. This work explores how it is possible to make use of side information that is often available in a typical communication network to check against substitution attacks made directly on raw messages by potential adversaries in the network. This frees the process of guaranteeing information integrity of the messages from the requirements of secrecy and authentication, and better isolates the mathematical structure that leads to information integrity in relation to the network topology. The separation principle developed in this work then allows one to more easily incorporate secrecy and authentication back into the overall information-theoretic security design. The broader implications of information-theoretic network security are increasingly manifest in electronic commerce, reliable communications, and confidentiality of legal, proprietary, diplomatic, and medical information.

信息理论安全是一门基于信息理论中的概念和技术来保护通信网络中信息的科学。 它包括防止网络中潜在对手进行的窃听、冒充和替换攻击。 虽然窃听和模仿攻击（和解决方案）得到了很好的研究，替代攻击，其中对手用来自同一来源的不同有效消息替换来自同一来源的消息，在日益网络化的世界中提出了新的风险。这项工作探讨了如何利用在典型的通信网络中经常可用的边信息来检查网络中潜在对手直接对原始消息进行的替换攻击。 这将保证消息的信息完整性的过程从保密和认证的要求中解放出来，并且更好地将导致信息完整性的数学结构与网络拓扑隔离开来。 在这项工作中开发的分离原则，然后允许一个更容易地将保密和身份验证回整体信息理论的安全设计。 信息理论网络安全的更广泛影响在电子商务、可靠通信以及法律的、专有的、外交的和医疗信息的保密性方面日益显现。
