Secrecy Capacities for Multiple Terminals
IEEE Transactions on Information Theory, 2004We derive single-letter characterizations of (strong) secrecy capacities for models with an arbitrary number of terminals, each of which observes a distinct component of a discrete memoryless multiple source, with unrestricted and interactive public communication permitted between the terminals.

Secrecy Capacity of Wireless LAN
2009 International Conference on Availability, Reliability and Security, 2009We address secure secret key distribution in wireless communication systems. There is the secrecy capacity concept that it can distribute information which the third parties can not eavesdrop because of the noise over the distribution channel. Then, we address secure secret key distribution in wireless communication systems using secrecy capacity ...

Secrecy Capacity of Wireless Channels
2006 IEEE International Symposium on Information Theory, 2006We consider the transmission of confidential data over wireless channels with multiple communicating parties. Based on an information-theoretic problem formulation in which two legitimate partners communicate over a quasi-static fading channel and an eavesdropper observes their transmissions through another independent quasi-static fading channel, we ...

Secrecy capacities for multiterminal channel models
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005Shannon-theoretic secret key generation by several parties is considered for models in which a secure noisy channel with one input terminal and multiple output terminals and a public noiseless channel of unlimited capacity are available for accomplishing this goal.

Having seized state power, the Bolsheviks pursued twin goals: to gain exclusive control of the state and the expansion of its capacities. The chapter reviews the various meanings and dimensions of “state capacity” and illustrates unique aspects of the capacity of communist states during the Cold War. Secrecy contributed to both twin goals, but beyond a

On the secrecy capacity of arbitrary wiretap channels
2008 46th Annual Allerton Conference on Communication, Control, and Computing, 2008We investigate the fundamental secrecy limits of arbitrary wiretap channels using the information-spectrum approach and we provide a random coding theorem for the secrecy capacity under various secrecy metrics. We show how our result specializes to several recent results, e.g., compound channels, parallel channels, and fading channels.

On secrecy capacity per unit cost
2009 IEEE International Symposium on Information Theory, 2009The concept of channel capacity per unit cost was introduced by Verdu in 1990 to study the limits of wideband communication. It was shown that an orthogonal coding scheme achieves the channel capacity per unit cost of memoryless stationary channels with a zero-cost input letter.

Secrecy transmission capacity of random networks
2013 Asilomar Conference on Signals, Systems and Computers, 2013We investigate the secrecy transmission capacity of random networks with Nakagami-m fading. Using a model that accounts for uncertainties both in node locations (distances) and channel coefficients (fading), we derive the path-gain distribution of the collusion of nodes, as well as the corresponding secrecy outage probability and secrecy rate ...

On the secrecy capacity of cooperative wiretap channel
2013 Iran Workshop on Communication and Information Theory, 2013Secure communications using physical layer characteristics has attracted many attentions in recent years. Secrecy capacity of communication systems can be increased by using multiple-antenna nodes. In this paper, we concentrate on the cooperative wiretap channel in which confidential messages are sent from a source to a legitimate receiver with the ...

Secrecy capacity of the Noise-Loop secure modulation
2014 4th International Conference on Wireless Communications, Vehicular Technology, Information Theory and Aerospace & Electronic Systems (VITAE), 2014The issues of privacy and security in wireless communication networks have taken on an increasingly important role as these networks continue to be deployed worldwide. Traditionally, security is viewed as an independent feature addressed above the physical layer and all widely used cryptographic protocols are designed and implemented assuming that the ...
