Title: Authentication side device, authentication system, and authentication method
Inventor: ARATAIRA SHIN
IPC: H04L9/08
Filed: 2018-09-27
Abstract: To safely and easily share a secret key only by an authentication side device and a client side device.SOLUTION: A entangled photon pair light source generates a quantum entangled photon pair made of a signal light quantum and an idler quantum. A first detection unit detects the signal light quantum to create transmission time information indicating a time detected. The idler quantum is transmitted to a client side device via a quantum channel. A determination unit acquires the number of simultaneous events and the number of elements of first time information by using the first time information acquired from the transmission time information and the time when the idler quantum was detected at the client side device, generates determination information containing information indicating an authentication in the case where both of the number of simultaneous events and the number of elements are within a preset setting value, and generates the determination information containing the information indicating denegation in other cases. When the determination information includes the information indicating the authentication, an advance common key is encrypted with a secret key in advance to generate a new advance common key.SELECTED DRAWING: Figure 1
