Research On Unified Authentication And Authorization And Application In Electric Vehicle Field

With advances of information science and extensive applications of network technology, all kinds of application system got rapid development and widespread popularity. However, different resource investment and different technology platforms of software and hardware in various periods lead to the significant differences in the construction of these applications. These application systems used different technology and architecture, with different user management, authentication, authorization and audit methods, and independent of each other. Based on the analysis of the various popular certification technology and extends of basic role-based access control model, we propose a4A norms. Based on combination of Java EE, Web Services, LDAP, single sign-on technology, this paper completed the authentication and authorization of unity, and clearly the demand for audit. This module applied in China potevio power network integrated monitoring and management system, and described its implementation methods. Enterprise trial showed that the4A framework achieved unified management and scheduling of authentication and authorization of application system. Due to the current electric vehicle field is in the initial state, so a unified authentication and authorization mechanisms of reasonable structure, formal content and clear hierarchy can provide a reference for others in the industry.
