Intrusion-tolerance is the technique of using fault-tolerance to achieve security properties. Assuming that faults, both benign and Byzantine, are unavoidable, the main goal of Int...
In this paper, we describe a novel approach to scalable group re-keying for secure multicast. Our approach, which we call Kronos, is based upon the idea of periodic group re-keyin...
A fairly common modern setting entails users, each in possession of a personal wireless device, wanting to communicate securely, via their devices. If these users (and their devic...
We describe models and efficient algorithms for detecting groups (communities) functioning in communication networks which attempt to hide their functionality – hidden groups. O...

Proposals for multicast security that have been published so far are complex, often require trust in network components or are inefficient. In this paper we propose a series of no...
