Abstract:
     The invention uses software encryption, the interleaver and recursive system code submodule in Turbo coding structure to make up cipher key that can encrypt the information source. Its system consists of an encryption module, an anti-interference decryption module and a cipher management software interface module. The encryption module is composed of the external interleaving scramble submodule, the Turbo encipher and cipher management submodule. Turbo encoder is adopted in the encryption module. The noise and other interference are reduced in the transmission of the encrypted information. The invention can be applied in secret information encryption like military intelligence.
