A Post-Office-Inspired Closed-Security-Ring Model for Web Service Flow

Inspired by post-office-federation, a security integrated model is designed. The model can provide convenient flexible security for Web service, and the closed-security-ring mechanism can integrate some security technologies in a completed procedure of business. The model includes four security control layers, and each layer provides different security function. The first layer can permit people to select proper security-grade for Web service. The second layer can ensure that Web service packages be securely transmitted. The third layer can fit complicated logical demands for commerce. The fourth layer can do a great deal of supervision to ensure the whole security. The mechanism running in the model is the closed-security-ring, which includes three security features such as closed-service-ring, closed-security-grade-ring, and closed-supervision-ring
