With the development of computer networks and object-oriented technology , distributed object computing technology came into being and access to a wide range of applications . CORBA ( Common Object Request Broker Architecture) specification is one of the mainstream of standard object-oriented distributed processing is becoming more perfect and mature . The CORBA components based on IEC61970 , 61968 Power system software development has important applications , but in practical applications , the system is running security must be guaranteed . Distributed object systems compared to conventional systems , there are more points of attack , and its application across the network is open, makes them very easy to be internal and external resources on the network attack . In addition, because of the heterogeneity of the distributed object system , bringing the inconsistency of the security model , but also makes the intruder more opportunities to undermine security . Therefore , to achieve the the CORBA system of security services is very necessary. This project will study the CORBA component safety management , and on this basis of power system software, security policy , and ultimately achieve the purpose of improving the system security level . This paper first studied the response of distributed systems are facing a series of security issues as well as one of the mainstream standard OMG CORBA distributed processing standards for these security issues . And then in the CORBA security services specifications, safety CORBA security infrastructure reference model on the basis of careful study , the combination of Universal Data Access ( GDA ) server , high - speed data access ( HSDA ) servers, and Historical Data Access ( TSDA ) server based actual security requirements of IEC 61970 power system software commonly used in the CIS server , typical scene in a detailed analysis of the CIS server security needs , design a CIS security services Framework based on the CORBA Security Service , that is one of the core security model , user perception Universal security Agent and interface level fine security controls two application modes. Finally, based on the current situation of the implementation of the CORBA security services , the TAO, Orbacus, JacORB other CORBA implementations to test the feasibility of the framework of the CIS security services carried out a detailed , fully verify the feasibility of the framework of the CIS security services .
