Attack-Resistance of Computational Trust Models

The World Wide Web encourages widely-distributed, open, decentralised systems that span multiple administrative domains. Recent research has turned to trust management [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 trust models. This paper describes the attack-resistance of several well-referenced trust models, in a move toward a possible framework and terminology for such analyses. We present a number of open questions, and consider possible future directions in the area. 1 Why Computational Trust Models? The World Wide Web encourages widelydistributed, open systems that span multiple administrative domains. Unfortunately, the characteristics of such systems mean that one cannot rely solely on traditional security measures. These ‘open distributed systems’ have a number of charac...
