摘要:

Chang et al. [Chin. Phys. B 23 010305 (2014)] have proposed a quantum broadcast communication and authentication protocol. However, we find that an intercept-resend attack can be preformed successfully by a potential eavesdropper, who will be able to destroy the authentication function. Afterwards, he or she can acquire the secret transmitted message or even modify it while escaping detection, by implementing an efficient man-in-the-middle attack. Furthermore, we show a simple scheme to defend this attack, that is, applying non-reusable identity strings.
