We review and consider the entanglement swapping of Bell states proposed by Zukowski et al. [Phys. Rev. Lett. 71(26) 4287]. We find a special class of Greenberger-Horne-Zeilinger states, and consider their entanglement swapping. We then show the applications of the entanglement swapping in quantum cryptography.
