Efficient genetic-based approach for web service security negotiation

Negotiation gets more attention in the field of business and becomes a more critical issue especially with the increasing use of services. In web services, negotiation is important for providers to meet consumers' expectation. For consumer and provider, security is an important concern. In this paper, an efficient genetic-based security negotiation approach for web service is proposed. A prototype is implemented for the proposed approach using JADE agent framework. To find a good fitness for the proposed genetic-based approach, we investigate different values for mutation rate and crossover rate. In addition, a comparison between the proposed approach, traditional time-based negotiation approach, and adapted traditional time-based negotiation approach is conducted. Furthermore, scalability tests, the execution time, and the success percentage of the three approaches are measured. From experimental results, the proposed approach outperforms the other two approaches.
