Study ATN Mobile Environment

Automated trust negotiation (ATN) gives a new solution for automated trustestablishment between strangers, which is a hot topic in the research field of computersecurity. In recent years, with the development of mobile Internet technology, mobilenetwork security become more prominent, and therefore mobile network automated trustnegotiation become more and more important. Mobile network ATN is researched in thispaper.Through studying the theoretical research results and practical experiences ontraditional network automated trust negotiation, this paper proposes a Mobile AdaptiveTrust Negotiation (MATN) model. In this model, depending on the trust negotiationprocess algorithms and features, automated trust negotiation will be divided into threestages. They are the pre-negotiation phase, the formal negotiation phase and the endnegotiation phase. Because of division stage, the evidence exposure sequence ofnegotiation can be found as soon as possible, the negotiations which contain policy conflictor ring strategy relies problem can be stop in advance. It can also reduce unnecessary trustcertificate exchange, saving mobile network bandwidth and computational overheadstorage capacity of the terminal.In this paper, each major modules of MATN model would be studied. A trustevaluation algorithm based on network behavior and negotiation history is proposed. It cantruly reflect the trust value between the two sides negotiated. Then an access controlpolicy-verification tree for the efficiently compliance check operation is proposed. In orderto achieve adaptive negotiation strategy, based on careful thought, drawing on ideas to cutnegotiation strategy, this paper designed a negotiation strategy which based on accesscontrol policy-disclosure tree. Finally, in order to reduce network bandwidth andcomputing overhead on the negotiation process, this paper proposes a certificate exchangeprograms which based on attribute disclosure.
