The Gaussian wire-tap channel
Wyner’s results for discrete memoryless wire-tap channels are extended to the Gaussian wire-tap channel. It is shown that the secrecy capacity C, is the difference between tbe capacit ies of the main and wire-tap channels. It is further shown tbat Rd= C, is the upper boundary of the achievable rate-equivocation region.
متن کاملAchievable Rates for the General Gaussian Multiple Access Wire-Tap Channel with Collective Secrecy
We consider the General Gaussian Multiple Access Wire-Tap Channel (GGMAC-WT). In this scenario, multiple users communicate with an intended receiver in the presence of an intelligent and informed eavesdropper who is as capable as the intended receiver, but has different channel parameters. We aim to provide perfect secrecy for the transmitters in this multi-access environment. Using Gaussian co...
متن کاملSecrecy Sum-Rates for the Multiple-Access Wire-Tap Channel with Ergodic Block Fading
We consider a two-user multiple-access wiretap channel that undergoes ergodic block fading. In this scenario, there are two users are communicating with a base station in the presence of an eavesdropper, who has access to the communications through a multiple-access channel. We assume independent fading for each block, and that the fading process is ergodic. We also assume that the channel gain...
متن کاملWire-Tap Codes as Side-Channel Countermeasure
In order to provide security against side-channel attacks a masking scheme which makes use of wire-tap codes has recently been proposed. The scheme benefits from the features of binary linear codes, and its application to AES has been presented in the seminal article. In this work – with respect to the underlying scheme – we re-iterate the fundamental operations of the AES cipher in a hopefully...
متن کاملSecrecy Capacity of the Gaussian Wire-Tap Channel with Finite Complex Constellation Input
The secrecy capacity of a discrete memoryless Gaussian Wire-Tap Channel when the input is from a finite complex constellation is studied. It is shown that the secrecy capacity curves of a finite constellation plotted against the SNR, for a fixed noise variance of the eavesdropper’s channel has a global maximum at an internal point. This is in contrast to what is known in the case of Gaussian co...
