Research And Implention Of Enterprise Supply Chain Security Based On PKI_PMI

With the global economy's developing, enterprises are using Internet to establish their supply chain's management systems, to adapt to the market's constant changes, to occupy more market share and to reduce the costs of production.. In the supply chain's mode, as joint enterprises were integrated in the same "chain", a business network to be threatened, then the whole supply chain network in all enterprises in the network at the same time threat. In the supply chain enterprise information integration, the higher the greater the threat, the threat of chain also the more obvious. The current situation is: on the one hand, the majority of manufacturing companies in order to survive and develop; there is an urgent need to implement supply chain management. On the other hand, the issue of information security at all times a threat to the supply chain nodes enterprises; enterprises that end often pay a heavy price. Clearly, the issue of information security has become a supply chain management of such enterprises operating mode application and development of the bottleneck.Based on the enterprise supply chain on its own characteristics, structure and operation process on the basis of the enterprise supply chain security threats facing the system was analyzed. And through the existing safety technology research, analysis of what technology to solve the current supply chain management system of information security is essential, which leads to PKI, PMI platform, and analysis of these two technologies to address enterprise supply chain system. The advantage of the security risks. Through the PKI structure, and the principle of trust model, designed a supply chain based on the trust business model, and this model applied to this paper, the security solution. Through the framework of the PMI, the authorized access control research programmed, introduced a role-based access control model PMI, and this model application in the enterprise supply chain in the possibility and necessity of an analysis.In this paper, we analyze the risk of the enterprise supply chain system. According to the security requirements of the enterprise supply chain system, we adopt delamination and modularization based on PKI/PMI flat to be deployed and introduce the technique of PKI PMI. We implement models using Web Service Component Architecture. SCM security scheme based on PKI/PMI can not only afford uniform authentication and access control service, but also implement logging in with one entry. The SCM security scheme combines the application system by the transverse model which is a centralized implement and can avoid repeated and low-level exploitation. The SCM security scheme which can afford an forwardly combinative mode that on API of application system must implement, makes the security and application system separate by setting up security filter which can be setted security strategy to service application system.SCM security based on pki_pmi can not only adapt dynamic, incompact and isomerase's characteristic of the enterprise supply chain, but also assure scm's safety, availability and agility. This paper detailedly describes the design of the security framework and implements the system with Web Service and JAVA technology...
