Abstract

The invention discloses a voice communication information source encryption system for a mobile terminal, comprising an analog-digital converter and a data encryption and decryption and phonological modem, wherein the analog-digital converter is used for converting an audio analog signal generated by a voice collector into voice data, or used for converting the audio data undergoing phonological encoding into an audio analog signal; the data encryption and decryption and phonological modem comprises a voice digital coding and decoding module, a security kernel module and a phonological modulation and demodulation module, wherein the voice digital coding and decoding module is used for performing digital voice compression on the converted audio data, the security kernel module is used for performing digital hardware encryption on the audio data subjected to digital voice compression, and the phonological modulation and demodulation module is used for performing phonological encoding onthe audio data subjected to digital hardware encryption. According to the invention, under the condition of not changing the voice communication procedure of the existing mobile terminal, voice communication information source encryption of the mobile terminal is realized, the encryption security is high, and the applicability is wide.

Description

technical field [0001] The invention relates to a voice encryption method for mobile communication, in particular to a voice communication information source encryption system for a mobile terminal. Background technique [0002] Existing mobile communication encryption schemes include VOIP encryption schemes, channel encryption schemes, source scrambling schemes, etc., but these schemes have many disadvantages, such as: limited to encrypted communications between devices of the same standard or the same model; their base stations And background servers need to be modified uniformly, increasing high operating costs, long development time cycle, heavy workload, unable to adapt to multiple mobile device systems, platforms and manufacturers; the software process of mobile terminal devices needs to be changed, and the underlying interface must be opened. It is easy to be hijacked or tampered with, resulting in system security holes of the mobile device itself being easily invaded...
