Jon Howell and David Kotz. A Formal Semantics for SPKI. In Proceedings of the Sixth European Symposium on Research in Computer Security (ESORICS 2000), pages 140-158, October 2000. Springer-Verlag. DOI 10.1007/10722599_9.

Abstract: 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 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.
