The development of e-commerce to the Internet information system , its openness to the environment , online fraud is inevitable , research has become a hot spot of the trust model . The entities involved in the trading activities of trust evaluation , either reduce transaction risks , but also improve the trading success rate . A complete trust model is not only to provide the entity of the trust evaluation algorithm , should also consider the value of the storage and management of the trust , to ensure the safety and reliability of the entity trust . Through research and analysis of the existing trust management mechanism , a service-oriented type of trust management framework , the architecture will be a variety of trust mechanisms set to conduct a comprehensive assessment and management of the trust as a whole , both entities trust assessment, but also to ensure the safe and reliable trust . Previous studies only one entity as the target of trust evaluation , there is no distinction between the types of services provided by the entity , the trust evaluation granularity thicker service-oriented type of trust evaluation algorithm STM , the algorithm considers trust itself has a characteristic , reference trading activities during the impact of the important factors of trust initial trust is provided for a new service or a new node's service node , can increase the chance of new nodes involved in the transaction , the right is given weight coefficient of the calculation method for the direct trust and recommendation trust respectively assigned different weights , integrated service trust entity . By setting certain parameters in the network environment , in order to reflect the feasibility and effectiveness of STM and get more random function parameters using Matlab simulation experiments from four aspects , given to verify that assurance recommended node quality , improve trading success rate , the comparison of the weight coefficient and overall trust services trust . Finally , in the Windows XP environment using the Java language , to utilize MyEclipse development tools , e-commerce prototype system based on mobile Agent for the background to achieve the trust model .
