With the rapid development of the Internet and communication technologies , to serve as the center to achieve the sharing of resources and work together more and more concern for people . However, the service center open network environment , the completion of a job usually requires the collaboration and cooperation of multiple entities located in different security domain , \trust relationship \As an emerging research directions in the field of access control , automated trust negotiation through reliable security gradually disclosure of digital certificates and access control rules to the requesting party , in order to achieve the establishment of the trust relationship between the strange entity , which provide access to security management domain the current automated trust negotiation has become the research focus of domestic and foreign researchers . Disclosed sequence and verify credential validity of the process need to consume more computing and communications resources in building trust certificates , there are automated trust negotiation framework and a practical evaluation of the efficiency of access control rules model , the premise ensure the security of sensitive information , be able to effectively enhance automated trust negotiation efficiency and success rate . The model based on the design of automated trust negotiation framework suitable for a P2P environment , the framework of a system prototype , and the corresponding expansion of the application of the framework , a service -oriented electronic automated trust negotiation framework to accelerate trust building . The two frameworks are able to ensure that sensitive information security , enhance automated trust negotiation efficiency and success rate , the framework through the effective use of the local the trust node and local node history negotiation information , sequence the cache , molecular sequence cache check vouchers , statements ticket , check the ticket and credential disclosure sequence prediction technology means automatically trust credential negotiation process by reducing the number of exchanges and validity of the number of checks to improve build trust card safe disclosure sequence efficiency , which enhance overall automated trust negotiation efficiency . The comparative experiment results show that the use of the automated trust negotiation framework , the automated trust negotiation efficiency and success rate has been improved .
