Recently, Yu et al. [Int. J. Theor. Phys., 2012, doi: 10.1007/s10773-012-1336-y] proposed a quantum secure direct communication (QSDC) with authentication using two non-orthogonal states. This study points out a pitfall in Yu et al.%26apos;s scheme, in which an eavesdropper can deliberately modify the message without being detected. Furthermore, an enhanced scheme is proposed to avoid the modification attack.
