  Article:   TOWARDS AUTOMATED EXECUTION OF SECURITY PROTOCOLS FOR WEB SERVICES.

Authors:  BÉLA GENGE.
 
       
         
  Abstract:  Existing solutions for authentication and authorization inWeb services make use of technologies such as SAML or WS-Security. These provide a static solution by using a set of predefined protocols. We propose a dynamic approach for the automated execution problem by developing a semantic security protocol model from which security protocol specifications are generated and automatically executed by participants. The proposed model consists of a sequential component, implemented as a WSDL-S specification, and an ontology component, implemented as an OWL specification. The correctness of the proposed model is ensured by using a set of rules and algorithms for generating it based on a protocol model given by the user. We validate our approach by generating and implementing several specifications for existing protocols such as the ISO9798 or Kerberos protocol.
