A cloudlet based security and trust model for e-government web services

Nowadays, Cloud Computing and Web services are the main backbone of e-government applications because of its interoperability and accessibility nature. Web services that are maintained in Cloud brought much attention in research and industry in terms of securing the communicated Web services. Thus, securing and trusting between the communicated Web services has been gradually becoming more challenging for Web services consumers, administrators, and Web service providers especially the egovernment services. Thus, In this paper, a Cloudlet based security trust model was proposed to guarantee a proper and secure communication between Web services through exploiting the cloud computing infrastructure. In addition, the proposed model is tackling the issues arises when Web service consumers are communicating with any of the e-governmental Web services through a trusted Cloud-based third party that is controlled by any governmental agency. Moreover, the Cloudlet is also used to measure the trustworthiness and conformance with the published policy by the provider of Web services through feedback from the Web service consumer. The experimental result of the proposed model shows an outstanding performance regarding different size of SoAP messages using triple DES and RSA as standard encryption algorithms.
