A secret handshake mechanism allows two entities, members of a same group, to authenticate each other secretly. This primitive was introduced recently by Balfanz, Durfee, Shankar, ...
In earlier work, we described a “pathological” example of a signature scheme that is secure in the Random Oracle Model, but for which no secure implementation exists. For that...
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...
Resource management is a central part of a Grid computing system. In a large-scale wide-area system such as the Grid, security is a prime concern. One approach is to be conservati...
