METHOD FOR AUTHENTICATING OF COMMUNICATION DEVICE AND DISTRIBUTING OF SESSION KEY USING UNITARY ALGORITHM

摘要

An object of the present specification is to provide a session key distribution method with improved stability. The session key distribution method according to the present specification is a method for distributing a session key between a session key distribution device connected to a quantum channel and a public channel and a communication device, wherein (a) the session key distribution device is previously shared with the communication device. Authenticating the communication device using long term key information; And (b) distributing the session key using a part of the quantum signals received in the process of authenticating the communication device by the session key distribution device.
