Title: The Innovations of Philip G Evans

Introduction

Philip G Evans is a notable inventor based in Knoxville, TN (US). He has made significant contributions to the field of quantum key distribution, with a total of 5 patents to his name. His work focuses on enhancing the security of communications within power grids and other applications.

Latest Patents

One of his latest patents is titled "Authentication of smart grid communications using quantum key distribution." This invention provides systems, methods, and computer-readable programs for authenticating unencrypted messages transmitted between two devices of a power grid over a public communications network. The authentication process utilizes a quantum-based secret key and an initialization vector generated from a quantum random number to create a payload for a transmission packet. The shared quantum-based secret key between the transmitting and receiving devices allows for verification of the packet's authenticity upon receipt.

Another significant patent is the "Passive continuous variable quantum key distribution scheme using a thermal source." In this invention, Alice splits the output of a thermal source into two beams, measures one locally, and transmits the other mode to Bob after applying attenuation. This method enables the establishment of a secure key based on measurements of the two beams without the need for a random number generator or an optical modulator.
