On the Study of Secrecy Capacity with Outdated CSI
2016In this paper, we study the secrecy capacity of the proposed transmission scheme. It is provided that the SNR at the selected best relay, destination and eavesdropper are same due to the symmetrical setup. The outage probability is considered here to evaluate the performance of such a secrecy communication system.

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.

Achieving secrecy: Capacity vs. resolvability
2011 IEEE International Symposium on Information Theory Proceedings, 2011In this paper, we investigate the nature of the coding mechanisms required to ensure strong secrecy over wiretap channels. Specifically, we analyze the limitations of capacity-based wiretap codes, i.e. wiretap codes that associate to each confidential message a subcode whose rate approaches the eavesdropper's channel capacity.

Capacity of Cognitive Interference Channels With and Without Secrecy
IEEE Transactions on Information Theory, 2009Like the conventional two-user interference channel, the cognitive interference channel consists of two transmitters whose signals interfere at two receivers. It is assumed that there is a common message (message 1) known to both transmitters, and an additional independent message (message 2) known only to the cognitive transmitter (transmitter 2). The

Secrecy capacity of the degraded Poisson wiretap channel
2010 IEEE International Symposium on Information Theory, 2010Providing security guarantees for the information “traveling” through the air is of critical importance for today's applications. Previous research concentrated on studying this problem when the medium used for communication is radio frequency (RF) channels.

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.

On the Secrecy Capacity of Fading Cognitive Wireless Networks
2008 3rd International Conference on Cognitive Radio Oriented Wireless Networks and Communications (CrownCom 2008), 2008In this paper, we compute the primary exclusive region (PER) and the secrecy capacity at a primary receiver in a fading cognitive radio network. We consider Rayleigh fading and log-normal shadowing. We also study the effect of secrecy capacity on the PER.

On the Secrecy Capacity of Distributed Storage with Locality and Availability
2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019In this paper, we extend the notion of locally recoverable codes with availability to secret sharing schemes. The main problem that we considered is how to store information using locally recoverable codes with all symbol locality and availability in such way that useful information can be recovered using an only small subset of coordinates while a ...

Probability of Secrecy Capacity of the MISO System with an Eavesdropper
2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016In this paper, we investigate the information- theoretic secrecy for an m-by-1 MISO system with an eavesdropper. We derive several closed-form formulas for the outage probability and the probability of strictly positive secrecy capacity for the concerned system. Moreover, a lower bound of the outage probability is also presented.
