| Summary: | 碩士 === 國立中正大學 === 通訊工程研究所 === 100 === In recent years, there are more and more web services which have participated in Internet. Automated Trust Negotiation (ATN) enables independent entities working together without human/manual interactions and prior trust relationships. The credentials are treated as tokens to establish trust between two strange entities, which can make connections and do business together if ATN is successful. A good ATN negotiation strategy should exchange sensitive credentials on an as-needed base. In this paper, we proposed a trust third party agent, Advanced NegotiatioN Agent (ANNA), for the advanced negotiation. The experiments show that ANNA is able to decrease unnecessary credential exchange and reduce the communication overhead in the trust negotiation process.
