摘要：

A protocol for multiparty quantum secret splitting (MQSS) with an ordered N Einstein-Podolsky-Rosen (EPR) pairs and Bell state measurements is recently proposed by Deng et al. [F.G. Deng et al., Phys. Lett. A 354 (2006) 190]. We analyzed the security of the protocol and found that this protocol is secure for any other eavesdropper except for the agent Bob who adopts intercept-and-resend attack. Bob can obtain all the information of Alice's alone without being found. We also propose an improved version of the MQSS protocol. (c) 2006 Elsevier B.V. All rights reserved.
