A Formal Semantics for SPKI
Jon Howell, David Kotz
Abstract : We extend the logic and semantic of authorization due to Abadi, Lampson et al. to support restricted delegation. Our formal model provides a simple interpretation for the variety of constructs in the Simple Public Key Infrastructure (SPKI), and lends intuition about possible extensions. We discuss both extensions that our semantics supports and extensions that it cautions against.
