摘　　要：1引言 目前,以Web服务为代表的软件服务及软件服务协同已成为一种新兴的Web应用形态.Internet-based Web application systems are gradually built as software service coordination systems. In an openi dynamic and collaborative application environment, traditional methods assumed with closeness, centralization and independence are not able to cope with these security problems efficiently. Trust management is a new method for dealing with security issues of open, distributed network application system. However, the traditional policy-based trust management systems have some shortcomings, i. e. complex in policy making, unable to deal with negative security credentials, etc. So, we design a trust management framework in combination with subjective trust model for software service coordination and security decision in Internet environment. This trust management framework has characteristics of operability, reasonability, and flexibility in policy setting.
