Abstract: In 2002, Li presented an asymmetrical quantum key distribution protocol which utilizes the correlations of Einstein-Podolsky-Rosen (EPR) pairs to establish a session key between two participants. Li claimed that an eavesdropper Eve cannot prevent his existence from being found by participants. However, this study shows that the session key can be obtained by Eve without being detected.
