Abstract :
Real time performance is in rigorous demand in substation. IEC 61850, the only international standard in substation automation system, makes clear requirements on it. However, the standard doesn´t give any instructive suggestions on security. Therefore, this paper puts forward an idea of encryption mixed by Data Encryption Standard (DES) and RSA public-key encryption algorithms to further ensure the message´s security while maintaining the real time performance. This idea combines the advantages and avoids the defects of either algorithm. The effectiveness of the proposed method is proved by the simulation for the GOOSE message of the substation´s transmission with OPNET as the network simulating software.
