Quantum Mechanics is one of the basic theories inmodern physics, which has been widely used in many modernapplications. In order to transmit a secure message, the deterministicsecure quantum direct communication protocol was proposed. It has attracted great interest of researchers afterwards. But the protocol was proved to have many vulnerabilities, andcan be attacked by eavesdropper. Many researchers have triedto improve it, with the concentration on the security detectionstrategy. In this paper, the symmetry Dicke state is used to detecteavesdropper. The quantum direct communication protocol thatuses symmetry Dicke state as security detection particle and themethod of entropy theory are introduced, and three detectionstrategies are compared. During the security analysis, we foundthat the efficiency of the propsoed mothed is higher than theoriginal "Ping-Pong" Protocol and the mothed that use twoparticles of EPR pair.
