Incremental trust: building trust from past experience

Emerging ubiquitous computing leverages the need for automated trust management models. We take a domestic network of both fixed and mobile nodes as our reference scenario and investigate how nodes can build trust exclusively based on their past experience. In a home network, trust propagation can be superfluous, while direct evaluation of peers' behaviour during repeated interactions has a key role. We present experimental results on the use of statistics for automated trust building and outline numerous issues that should be analysed further.
