Chaotic elliptic map for speech encryption

Using a new key management system and Jacobian elliptic map, speech encryption scheme has been developed for secure communication data. map-based as novel method to improve the existing methods' drawbacks, such poor quality in decrypted signals, residual intelligibility, high computational complexity, low-key space. map solution, cryptosystem was created. The proposed scheme's performance is evaluated using spectrogram analysis, histogram space correlation sensitivity analysis randomness test analysis. results, we can conclude that provides better security with robust decryption quality.
