Abstract

The World Wide Web encourages widely-distributed,open, decentralised systems that span multiple administrative domains. Recent research has turned to trustmanagement [4] as a framework for decentralising security decisions in such systems. However, whilst traditional security measures such as cryptography and encryption are well-understood (theoretically and empirically), the same cannot be said for computational trustmodels. This paper describes the attack-resistance ofseveral well-referenced trust models, in a move toward apossible framework and terminology for such analyses.We present a number of open questions, and considerpossible future directions in the area.
