Research On A Distributed CORBA Security Communication Mechanism

CORBA is the way to solve the interconnection between different hardware and software systems in Distributed Computing Environment, to enhance the interoperability between network software,to cover the shortage of distributed computing in the traditional distributed computing model. While enhancing interoperability between software systems, then structure flexible distributed applications become possible. Currently, CORBA distributed systems have been more widely applied in communications, finance and other fields,on the one hand,communications security is very importent in these areas.On the other hand, distributed systems due to its own networking and isomerization faced with greater security than conventional systems risk. Therefore, CORBA security systems are paid more and more attention.With the development of informatization, distributed systems security requirements will be higher. But most CORBA system does not support secure communications. CORBA security has been defined by OMG, so that safety communication between CORBA systems to be possible.Current mainstream open source middleware like TAO, Jac ORB, Omni ORB. TAO which is mainly based on C ++ development, Jac ORB mainly based on JAVA development, while Omni ORB based on C ++ and Python. Therefore, this three kinds of CORBA middleware software to be universal. without modifying the source code, by accessing secure communication platform,CORBA systems can achieve safe mode.By compiling IDL files, so secure communication platform acts as a virtual client and server, when a client requests a operation from server, first through the secure communications platform, secure communications platform records to the in-parameters, IP and port. Then the secure communication platform acting as a virtual client request server by secure mode which have been configured, sent the parameters which have been saved to server. The return value which come from the server firstly send to secure communications platform, and then sent to the client by secure mode.Without modify the software source code Client and server can communicate securely by a secure communications platform.By this way CORBA systems can meet the growing security requirements.
