Genetic-based Approach for Security Policies Negotiation in Web Service Environment

摘要

Web services is an important in the future internet especially in the field of business. The secure interaction between requester and the provider of the service is one of the main problems. This secure interaction requires negotiation and an agreement about their security requirements. In this study, a genetic-based approach is proposed for SOAP message security negotiation. The proposed approach covers the negotiation problem as a search space of solutions for different participants. Various security levels are proposed. These levels include three key security objects identity, integrity and confidentiality of SOAP messages. The proposed Genetic-based security negotiation approach is compared with traditional time-based negotiation and the adapted traditional time-based negotiation approaches. A telemarketing case study is addressed through experimental results. Besides, the execution time and message complexity of the three approaches are provided. Experimental results show the efficiency and effectiveness of the proposed approach compared to other two approaches.
