We extend the logic and semantics of authorization due to Abadi, Lampson, et al. to support restricted delegation. Our formal model provides a simple interpretation for the variety...
Usage control is a generalization of access control that also addresses how data is used after it is released. We present a formal model for different mechanisms that can enforce ...

We intend to narrow the gap between concrete implementations of cryptographic protocols and their verified models. We develop and verify a small functional implementation of the T...
We address the problem of fairly distributing the cost of system-wide improvements to the security of a transportation infrastructure over the beneficiaries. We present a framework...
We address the insecurity problem for cryptographic protocols, for an active intruder and a bounded number of sessions. The protocol steps are modeled as rigid Horn clauses, and t...
