We consider an amplify-and-forward relay network composed of a source, two relays, and a
destination. In this network, the two relays are untrusted in the sense that they may perform …

This paper presents a random coding scheme with which two nodes can exchange
information with guaranteed integrity over a two-way Byzantine relay. This coding scheme is …

This paper focuses on Byzantine attack detection for Gaussian two-hop one-way relay
network, where an amplify-and-forward relay may conduct Byzantine attacks by forwarding …

The goal of this paper is to obtain the channel conditions (if exist) under which substitution
attacks performed by relay node (s) in a relay network can be detected. The network model …

We consider Byzantine attack detection for Gaussian two-way relay network which carries
large volumes of data. Two source nodes communicate with each other with the help of an …

This paper focuses on Byzantine attack detection for Gaussian two-way relay network. In this
network, two source nodes communicate with each other with the help of an amplify-and …

The problem of two sources wanting to share information through a potentially untrustworthy
relay node is considered. The two sources transmit symbols simultaneously, and the relay …

The Web not only contains a huge amount of information, but also provides a powerful
infrastructure for communication and information sharing. While mining for valuable …

This dissertation introduces the concept of Information Integrity, which is the detection and
possible correction of information manipulation by any intermediary node in a …
