Abstract
An authentication method for a QKD process includes: a sender selects a basis for preparing authentication information according to an algorithm in an algorithms library, and respectively applies different wavelengths to send quantum states of control information and data information according to a preset information format; a receiver filters the received quantum states, employs a basis of measurement corresponding to the algorithm to measure the authentication information quantum state, sends reverse authentication information when the measurement result is in line with the algorithm, and terminates the distribution process otherwise. In addition, the sender terminates the distribution process when its local authentication information is inconsistent with the reverse authentication information.
