Group communication has become an important component in wireless networks. In this paper, we focus on the environments in which multiple groups coexist in the system, and both in...
This paper describes a Secure INtrusion-Tolerant Replication Architecture1 (SINTRA) for coordination in asynchronous networks subject to Byzantine faults. SINTRA supplies a number...
This paper studies non-cryptographic authenticated broadcast in radio networks subject to malicious failures. We introduce two protocols that address this problem. The first, Nei...

The capacity of the Gaussian wiretap channel model is analyzed when there are multiple antennas at the sender, intended receiver and eavesdropper. The associated channel matrices a...
Secure communication in distributed systems is notoriously hard to achieve due to the variety of attacks an adversary can mount, based on message interception, modification, redi...
