INFORMATION THEORETICALLY SECURE KEY EXCHANGE ALGORITHM
Advances and Applications in Discrete Mathematics, 2023Summary: We propose an algorithm that enables secure information and communication channel based on perfect end-to-end key-exchange scheme. The secure channel between two users enables each user to use the public key of the other user to derive a specific private key for both users.

Biometric Security from an Information-Theoretical Perspective
Foundations and Trends® in Communications and Information Theory, 2012In this review, biometric systems are studied from an information theoretical point of view. In the first part biometric authentication systems are studied. The objective of these systems is, observing correlated enrollment and authentication biometric sequences, to generate or convey as large as possible secret keys by interchanging a public message ...

The complexity of information theoretic secure computation
2012 IEEE Information Theory Workshop, 2012A protocol for secure computation allows two or more parties to perform a distributed computation on their local inputs while hiding the inputs from each other. In the so-called “information theoretic” setting for secure computation, the parties are assumed to communicate over secure channels and the inputs should remain hidden even from ...

Information-Theoretic Security in Stochastic Control Systems
Proceedings of the IEEE, 2015Infrastructural systems such as the electricity grid, healthcare, and transportation networks today rely increasingly on the joint functioning of networked information systems and physical components, in short, on cyber–physical architectures. Despite tremendous advances in cryptography, physical-layer security and authentication, information attacks ...

Information-theoretically secure key generation and management
2017 IEEE International Symposium on Information Theory (ISIT), 2017In this paper, we address the problems of key generation and management for enabling one-key-for-one-file secure encryption, where every file is encrypted by using an independent random key, which is highly desired in long-term protection of data stored on public clouds and other applications.

Information-Theoretic Security as an Optimization Problem
Journal of Next Generation Information Technology, 2011Quantum key distribution is renowned for information-theoretic security on point-to-point connections, while it is by itself not directly capable of end-to-end security. Multipath transmission is known for perfect end-to-end security, provided that perfect point-to-point security is achievable.

Connectivity of wireless information-theoretic secure networks
2014 IEEE Global Communications Conference, 2014Connectivity is one of the most fundamental properties of wireless multi-hop networks. This paper studies the connectivity of large wireless networks with secrecy constraint, i.e. a pair of nodes can communicate securely against eavesdropping. Specifically, we consider a network with a mixture of legitimate nodes and eavesdroppers that are distributed ...

Information-Theoretic Security
2015Information theory is one of the foundations of computer science. In this chapter we will examine its relationship to cryptography. But we shall not assume any prior familiarity with information theory.

Information-theoretic secure identification
Proceedings. 1998 IEEE International Symposium on Information Theory (Cat. No.98CH36252), 2002Secure identification has been based on unproven computational complexity assumptions or the correctness of quantum physics. In this paper we present unconditionally secure identification allowing active attacks.
