Abstract:
The evolution of the World Wide Web has created a new environment where people can interact, e.g. talk to their friends, shop online, conduct business meetings, etc. Trust and trustworthiness are central notions in human interaction; in particular, they represent important criteria for every Internet user because of the multitude of choices they are faced with when choosing whom to interact with.
This paper presents a simulation model implemented in Ptolemy II for the simulative analysis of trust policies in networked environments, called communication space (CS). The model reflects both the CS structure e.g. principals, roles, and event structure, and the interactions between the elements of CSs. Principal behavior is based on Markov chains and on criteria for selecting peers that initiate transactions. We investigate the efficiency of trust policies based on local observations and evaluation of interactions by examining a case study based on the popular auction site eBay.
