A security-enhanced encryption scheme on power system real-time data communication

This paper provides an introduction and overview of power system real-time data encryption under network environment, describes the encryption requirements of power system real-time data communication, and briefly introduces a new type of a security-enhanced power system data encryption scheme. The QKD-based encryptions can delivering end-to-end network security via high-speed quantum key distribution, and against sophisticated eavesdropping attacks. QKD will be a most promising way of real-time data encryption in power system in the future.
