Study on the Key Distribution Mechanism of Feeder Automation System
Jia Lin Song, Lin Li Wu · Advanced materials research · 2012
Along with the development of information technology, the information security of power industry is becoming an important problem in the stability of power systems. In order to solve the key distribution problems of feeder automation system, a key agreement and mutual authentication scheme based on elliptic curve cryptograph techniques is proposed. The mutual authentication and agreement on a secure session key is realized, between feeder terminal unit (FTU) and regional substation. By using the ECC techniques, greater security with fewer bits is provided. As the result, the requirement of bandwidth is decreased, furthermore, computational burden and storage requirement is also lowered on the FTU.
