Abstract:
Combining with the technologies of invertible two-dimensional Arnold transform and improved algorithm Logistic mapping,a chaotic voice encryption algorithm is investigated based on the particularity of the encryption of voice,and then a voice encryption system solution is proposed to realize the voice encryption and decryption using the Digital Signal Processor TMS320VC5509A.The basic principle and method of data encryption is first introduced and a detailed design plan of software and hardware for the chaotic voice encryption system is presented,at the same time we realize the chaotic voice encryption and decryption using the DSP chip.Finally,through simulation and experimental test for voices,the waveforms and spectrums collected before encryption and after decryption show good agreements with each other,suggesting the feasibility of the proposed chaotic voice encryption algorithm.
