| Abstract: | In view of the real-time property of speech,and based on the advantages and disadvantages of chaos masking, chaos modulation in speech encryption,a new kind of scheme for chaos switching encryption was constructed to encrypt speech effectively. The computational approaches realized the encryption of speech, and the results verified the feasibility of the scheme.Meanwhile,the encryption and decryption affections, anti-attacking, synchronization time and cryptosystem security were analyzed and compared. |
