An interesting protocol for quantum identity authentication on a basis of the classic shared secret has been presented recently (Hong et al. in Quantum Inf Process 16(10): 236, 2017). It requires few resources and it is technologically feasible. Its seminal analysis focuses on average eavesdropper’s information gain per single protocol run—a parameter suitable for estimation of the security margin applicable to the protocols aiming at provision of confidentiality. However, the security… CONTINUE READING
