摘要：

Recently, an enhanced multiparty quantum secret sharing of classical message by using entanglement swapping was presented. In this protocol, a code table was used to improve the efficiency. However, as we show, this protocol is insecure in the sense that an outside attacker or two special dishonest agents can eavesdrop part or all information about the secret. Hence, this high efficiency may be unrealistic because it results in the decrease of security.
