Abstract

In 2009, Yen et al. [Quantum Inf. Comput. 9(5-6):376-394, 2009] proposed a quantum direct communication along with an authentication protocol using Einstein-Podolsky-Rosen states. This study points out several attacks on Yen et al.'s protocol, in which a malicious Trent can launch either an intercept-resend attack to reveal the secret information of a sender or an impersonation attack to impersonate a sender to send forged secret information to a receiver. Furthermore, an outsider can launch a modification attack to modify the secret information of a sender. A possible solution is proposed herein to avoid these security attacks.
