Abstract: This paper analyzed the quantum identity authentication technology in the network environment and brought forward a scheme of quantum identity authentication based on the swapping of the EPR entanglement and analyzed its security.Thus a scheme of sharing secret key string between two sides in the distributed network environment was presented.It made use of the entanglement swapping to authenticate the identity.

Key words: quantum cryptography, entanglement swapping, identity authentication
