A controlled deterministic secure quantum communication(CDSQC) protocol is proposed based on threeparticle GHZ state in X-basis.Only X-basis and Z_1Z_2X_3-basis(composed of Z-basis and X-basis) measurement are required,which makes the scheme more convenient than others in practical applications.By distributing a random key between both sides of the communication and performing classical XOR operation,we realize a one-time-pad scheme,therefore our protocol achieves unconditional secure.Because only user with legitimate identity string can decrypt the secret,our protocol can resist man-in-the middle attack.The three-particle GHZ state in X-basis is used as decoy photons to detect eavesdropping.The detection rate reaches 75% per qubit.
