Abstract:

Liu et al. (Int. J. Theor. Phys. 58(5), 1659–1666 2019) proposed a multi-party quantum key agreement protocol with Bell states and single particles. They claimed that their protocol can resist the participant and outside attacks. However, we found that their protocol does not provide the fairness property and cannot resist collusion attac...More
