MIMOME channel secrecy capacity
2008 11th International Conference on Computer and Information Technology, 2008Although conventional cryptographic security mechanisms are essential to the overall problem of security, the openness of wireless medium poses both threats and opportunities for securing transmission. Information theoretic security is attracting researchers for its robust nature.

On Multiterminal Secrecy Capacities
2007 IEEE International Symposium on Information Theory, 2007Shannon-theoretic secret key generation by several parties is considered for source models in which the distinct components of a multiple source observed separately by multiple terminals, and for channel models in which a secure noisy channel with one input terminal and multiple output terminals, and, additionally in both cases, a public noiseless ...

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.

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 heterogeneous distributed storage systems
2014 6th International Symposium on Communications, Control and Signal Processing (ISCCSP), 2014The capacity and secrecy capacity of heterogeneous distributed storage systems under repair dynamics are studied. Capacity bounds are given depending on the average resources per node. One implication of these results is that symmetric repair maximizes the capacity of a homogeneous system.

Secrecy capacity of MIMO channels
2008 International Conference on Electrical and Computer Engineering, 2008A Gaussian multiple input multiple output (MIMO) channel is considered where a transmitter is communicating to a receiver in the presence of an eavesdropper. The transmitter is equipped with multiple antennas, while the receiver and the eavesdropper also contains multiple antennas. We present a technique for determining the secrecy capacity of the MIMO

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 ...

This chapter introduces the zero-error secrecy capacity of quantum channels (ZESC), defined as the higher transmission rate that can be achieved by noisy quantum channels, allowing for the transmission of classical information without errors in an unconditionally secure way.

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 ...
