Abstract

For the clear storage of database file in distribution automation system ,information transmitted in plaintext and weak identity authentication and other information security issues, we propose the project of combining the firewall based on active defense and the intrusion detection based on passive defense.Finally, we analysis the safety property of this scheme, the analysis shows that this scheme meets the security requirement of distribution automation system, forever ensure the security of the power distribution automation system mutual communication better. © 2012 Springer-Verlag.
