SPKI/SDSI is a language for expressing distributed access control policy, derived from SPKI and SDSI. We provide a first-order logic (FOL) semantics for SDSI, and show that it ha...
We present a new technique for generating a formal proof that an access request satisfies accesscontrol policy, for use in logic-based access-control frameworks. Our approach is t...
