A Semantic Web Service (SWS) is a software system designed to support interoperable application-to-application interactions over the
Internet. SWSs are based on a set of XML standards, such as Web Service Description Language (WSDL), Simple Access Object Protocol
(SOAP) and Universal Description, Discovery and Integration (UDDI). So far these services and the corresponding provider’s URLs are
advertised on specific UDDIs. As such, after finding the requested service any given client contacts the right provider to negotiate the service
access procedure. These first contacts between clients and providers are usually not protected (Encrypted), the non-possession of public key
infrastructure (PKI) especially by clients can be considered among the main cause behind this security problem. In this paper, we propose a
securing approach based on PKI infrastructure and UDDI functioning, which must play in addition to its initial missions the role of a trust centre,
leading to adequate security for semantic web services. The authentication and authorization information is exchanged using SAML (Security
Assertion Markup Language), ratified by OASIS standards.
