Abstract:

Based on analyzing the requirements of Web services security, the paper proposes an extensible secure semantic Web services architecture（SSWSA）, and  introduces the process of dynamic service discovery, service engagement, service enactment and management, security hierarchy, and the corresponding se curity strategy of the model. The security of semantic Web services is improved effectively by extending the security of protocol stacks and appending a role of security certification.

Key words: semantic Web services, dynamic service discovery, protocol stack, security certification role
