Abstract

In a recent paper [C.H. Hong et al., Opt. Commun. 283 (2010) 2644], a n-user quantum key distribution protocol with n quantum channels was presented. By analyzing its security, it is shown that this protocol is insecure for Trent, a dishonest third party, who can steal the key without being detected by a special attack strategy. We give a description of this strategy and then put forward an improved protocol, which can stand against this attack. Furthermore, the improved protocol is feasible in the current technology conditions, because it is just required an incomplete Bell-state measurement in implementation of it.
