A different quantum cryptography key distribution way based on the orthogonal states is presented in the system, instead of using two sources [Phys. Rev. Lett. 75 (1995) 1239], only one source and one channel are needed to produce two orthogonal states by modulating phase. It is very easy to realize this method in practice.
