摘要： the present invention provides a method for authenticating a user in a multiparty quantum communication comprising: generating l quantum entangled states with N particles and transmitting each particle of the l quantum entangled states to N users, by a quantum communication server, wherein the N is a natural number larger than 2; determining, by the quantum communication server, whether a disguised attacker exists among N users on the basis of a first error rate calculated by using n quantum states randomly selected from the l quantum states possessed by the users respectively and a previously shared secret key in each of the users; and controlling, by the quantum communication server, each of the users to generate a new secret key using mk quantum states and replace the previously shared secret key with the new secret key.
