Key Establishment Scheme for Distribution Automation System Using Logical Key Hierarchy Approach
Zhong Wei Sun, Rong Gang Zhang, Dan Liu · Advanced materials research · 2011
Ethernet Passive Optical Networks (EPONs) are promising communication technologies for distribution automation system (DAS). However, EPONs have very specific security requirements, due to the broadcast character of the transmission medium. Based on the identity-based cryptography (IBC), and utilizing logical key hierarchy (LKH) approach, this paper presents an efficient key establishment scheme for distribution automation system using EPON. And the analysis results are also given in the paper.
