The Design Of Encryption Chip Based On Permutation Code And Its Research On Voice Communication

This paper analyses the encryption algorithm, especially symmetrical encryption algorithm, gives two principles that block cipher needs for research, and describes Permutation Code's contribution for symmetrical encryption algorithm genealogically. Then supplies realization of Encryption Chip based on Permutation Code by EDA, and integrates the modular of signal gathering so the chip can be used in voice communication encryption.The structure introduces firstly rudimentary knowledge and principle and then introduces implementation method and measure. Firstly, this paper analyses the research background of the encryption chip and tells why choose Permutation Code through theoretical explanation;Secondly designs the Encryption Chip based on Permutation Code;Lastly, gives the encryption chip's application plan in voice communication encryption.
