Abstract
Systems, methods, and computer-readable programs are provided for authentication of unencrypted message(s) transmitted between two devices of a power grid over a public communications network are provided. The authentication uses a quantum-based secret key and an initialization vector generated from a quantum random number to generate a payload for a transmission packet. The quantum-based secret key is shared between the transmitting device and the receiving device. When the receiving device receives the packet, the receiving device uses the shared quantum-based secret key and the initialization vector to verify whether the payload in the packet is authentic.
