ABSTRACT
Trust management is a buzzword that means many different things to different people. However, everyone agrees that the term encompasses distributed naming and authorization systems. The SDSI work (later combined with SPKI) has been one main thrust of trust management research. Unfortunately, formalizing SDSI/SPKI has not proven easy. In this work, we describe an alternative design, based on very simple formal semantics. In particular, we show that naming and authorization can be considered separately, and compose nicely.
