    摘要： A method of user-authenticated quantum key distribution according to the present invention shares a position having the same basis without making public basis information using previously shared secret keys and authenticates a quantum channel by confirming whether there is the same measured outcome at that position, in order to secure unconditional security of BB84 quantum key distribution (QKD) protocols vulnerable to man-in-the-middle attack.

    摘要： A method and system for performing a quantum bit commitment protocol is provided. The method of performing a quantum bit commitment protocol to send bit information from a first party to a second party includes a pre-commit phase to randomly select and send, by the second party, a quantum state to the first party; a commit phase to perform, by the first party, a unitary transformation on the quantum state to combine the bit information with the quantum state and send the unitary-transformed quantum state to the second party; a hold phase to hold the unitary-transformed quantum state for a predetermined time period; and a reveal phase to provide, by the first party, information about the unitary transformation to the second party to open the bit information to the second party. The reveal phase may include a verification process to check if the opened bit information matches the bit information committed in the commit phase. For example, the verification process may be performed by checking if a quantum state obtained by performing an inverse unitary transformation of the unitary-transformed quantum state matches the quantum state selected in the pre-commit phase.

    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.
