CORBA组件在电力系统运行安全管理中的应用研究

Research on application of CORBA components in power system operation safety management

文中针对面向对象的分布式软件在电力系统运动过程中更容易遭受外部和内部资源攻击的特点,研究了基于CORBA组件的电力系统运行安全管理办法。利用CORBA具有保证系统稳定的安全技术特征,在其安全服务规范的基础上,设计了基于CORBA组件的应用参考模型CIM和CIS安全服务框架。CIS安全服务框架通过ORB层面上实现通用的安全代理,以及开发过程控制API进行系统安全代理的方式构建了具有结构清晰、扩展灵活的安全应用体系。为了对系统的可靠性进行验证,文中以开源的CORBA产品为测试对象,利用TAO、Orbacus、Jac ORB分别对其Security Unaware Application、Security Policy Controller Application和Security Policy Enforce Application三个层次进行了测试,充分验证了系统的安全性。本研究内容对于CORBA组件在电力系统运行安全管理中的应用具有重要意义。

In this paper,aiming at the characteristics that the object-oriented distributed software is more vulnerable to external and internal resources attack in the process of power system movement,the method of power system operation security management based on CORBA components is studied. Based on the security service specification of CORBA,this paper designs the application reference model CIM and CIS security service framework based on CORBA components on the basis of the security service specification. The CIS security service framework builds a security application system with clear structure and flexible extension through the implementation of general security agents on the ORB level and the development process control API for system security agents. In order to verify the reliability of the system,this paper takes the open source CORBA product as the test object and uses TAO,Orbacus,and Jac ORB to test its Security Unaware Application,Security Policy Controller Application and Security three levels,and fully verify the security of the system. The research content of this paper is of great significance for the application of CORBA components in power system operation safety management.
