Ensuring smart grid meter security

Posted: 10 Jan 2011     Print Version  Bookmark and Share

Keywords:smart grid  meters  communication keys 

Addressing the security of meters in emerging smart grid applications requires a secret key management strategy that does not store keys on any node, authenticates each node, verifies communications, and uses temporary communication keys that are rotated often.

Securing embedded system nodes on any networking platform requires a standard interface for communication which in turn necessitates that all nodes talk the same "language" and provide data in the same format.

The emerging smart grid standards could provide standard data and communication formats. But such a standard raises a larger question; who or what would keep anyone listening on the network from understanding and using the data for their own purposes?

On a smart grid network, each node or network of nodes may communicate to each other over a different medium, the systems may have different processing power, storage capabilities, operating systems (or lack of), and/or application software. Such systems may use advanced encryption algorithms, and verification schemas to ensure communications are unaltered. Each node may be so different from the next that the largest security facet is obscurity of the systems themselves.
