Authenticated Multiparty Quantum Secure Direct Communication with Dense Coding

摘要：

In this paper,three efficient authenticated multiparty quantum secure direct communication protocols are presented by using multi-particle GHZ states and dense coding,each of which is suitable to a special scenario.These protocols show more efficiency on messagetransmission,and the anticipatorsidentity key can be repeatedly used for a long term.Security analysis shows they are secure against outer Eves attacks and inner anticipators attacks.
