Abstract

Correlated sources are present in communication systems where protocols ensure that there is some predetermined information for sources. Here correlated sources across an eavesdropped channel that incorporate a heterogeneous encoding scheme and their effect on the information leakage when some channel information and a source have been wiretapped is investigated. The information leakage bounds for the Slepian-Wolf scenario are provided. Thereafter, the Shannon cipher system approach is presented. Further, an implementation method using a matrix partition approach is described.

Correlated Source Coded Sequences with Compromised Channel and Source Symbols using Shannon's Cipher System

Reevana Balmahoon, A. J. Han Vinck, Ling Cheng

Correlated sources are present in communication systems where protocols ensure that there is some predetermined information for sources to transmit. Here, two correlated sources across a channel with eavesdroppers are investigated, and conditions for perfect secrecy when some channel information and some source data symbols (the predetermined information) have been wiretapped are determined. The adversary in this situation has access to more information than if a link is wiretapped only and can thus determine more about a particular source. This scenario caters for an application where the eavesdropper has access to some preexisting information. We provide bounds for the channel and key rates for this scenario. Further, we provide a method to reduce the key lengths required for perfect secrecy.

Information leakage for correlated sources with compromised source symbols over wiretap channel II

Reevana Balmahoon, A. J. Han Vinck, Ling Cheng

Correlated sources are present in communication systems where protocols ensure that there is some predetermined information for sources. Here, we investigate two correlated sources across the wiretap channel II and their effect on the information leakage when some channel information and some source data symbols (the predetermined information) have been wiretapped. The adversary in this situation has access to more information than if a link is wiretapped only and can thus determine more about a particular source. We show that since the sources are correlated, if the information on one link and a portion of its data symbols are compromised then there is also information leakage for the other source. Further, we describe a method to reduce the information leakage for the scenario where the information from the source data symbols overlaps with the channel information.

Information Theoretical Analysis of Side-Channel Attacks to the Shannon Cipher System

Yasutada Oohama, Bagus Santoso

We study side-channel attacks for the Shannon cipher system. To pose side channel-attacks to the Shannon cipher system, we regard them as a signal estimation via encoded data from two distributed sensors. This can be formulated as the one helper source coding problem posed and investigated by Ahlswede, Korner(1975), and Wyner(1975). We further investigate the posed problem to derive new secrecy bounds. Our results are derived by a coupling of the result Watanabe and Oohama(2012) obtained on bounded storage eavesdropper with the exponential strong converse theorem Oohama(2015) established for the one helper source coding problem.

Secure lossy source-channel wiretapping with side information at the receiving terminals

Joffrey Villard, Pablo Piantanida, Shlomo Shitz Shamai

The problem of secure lossy source-channel wiretapping with arbitrarily correlated side informations at both receivers is investigated. This scenario consists of an encoder (referred to as Alice) that wishes to compress a source and send it through a noisy channel to a legitimate receiver (referred to as Bob). In this context, Alice must simultaneously satisfy the desired requirements on the distortion level at Bob, and the equivocation rate at the eavesdropper (referred to as Eve). This setting can be seen as a generalization of the conventional problems of secure source coding with side information at the decoders, and the wiretap channel. Inner and outer bounds on the rate-distortion-equivocation region for the case of arbitrary channels and side informations are derived. In some special cases of interest, it is shown that separation holds. By means of an appropriate coding, the presence of any statistical difference among the side informations, the channel noises, and the distortion at Bob can be fully exploited in terms of secrecy.
