SSH-Based CA System Model Framework for Research and Design

PKI-based CA system scalability and system maintenance is a research hotspot, the main line of business processes, combined with modern software engineering methods, the traditional architecture of the CA system are analyzed to identify the CA system in the expansion of and maintenance deficiencies, separation of the business to break the traditional way, using the idea of hierarchical tasks, By SSH three tectonic framework of a new model of the CA system, and gives the corresponding icon shows that the corresponding instance of the final as an example, the model described in detail in the data and business logic scalability and maintainability improvements done, and the use of the benefits of the model (system security, information confidentiality, integrity and anti-repudiation of information).
