A theoretical scheme of quantum secure communication using a class of three-particle W states is proposed. In the scheme,two communicators may communicate after they test the security of the quantum channel.The receiver can obtain the secret message determinately if the quantum channel is safe.The present scheme can be realized without using teleportation.

A theoretical scheme of quantum secure communication using a class of three-particle W states is proposed. In the scheme, two communicators may communicate after they test the security of the quantum channel. The receiver can obtain the secret message determinately if the quantum channel is safe. The present scheme can be realized without using teleportation.
