Inspired by the local indistinguishable of orthogonal product states, in our scheme, the classical message can be blinded by eight orthogonal product states which can avoid preparing higher-dimensional entangled states. And also inspired by the concept of quantum teleportation, our protocol can recover the original message via the five-particle entangled state sequence instead of transmitting the original message directly in the quantum channel. In this way, long distance communication can be realized between two communication participants and the probability of eavesdropping in the transmission channel is reduced. In addition, in the ideal quantum channel condition without noise, the security of the proposed scheme under some common eavesdropping attacks is validated.
