Study on Enhancing Performance of Ad Hoc Trust Model with Family Gene Technology

This paper analyzes the deficiencies of current trust systems based on PKI (Public Key Infrastructure), ambiguity certificate principal information, and complicated identification process. Inspired by biologic gene technique, we propose a novel Ad Hoc Trust model based on Family Gene (ATFG) model. The model answers the existing questions in tradition trust model by adopting the technology of family gene. The concepts and formal definitions of Family Gene in the Ad Hoc trust security domains are given. Then, the mathematical models of Family Gene are established. Our theoretical analysis and experimental results show that the model is a good solution to Ad Hoc trust domain.
