Securing Speech Transmission based on DNA and S-Box techniques

What is it about?

In this article, we presented a two-step safe cryptographic method for speech transmission: a suggested scrambling algorithm is suggested to verify that the actual speech signal is changed as a result of a suggested speech signal transferring algorithm, an encryption scheme for the scrambled speech signal is suggested based on the coding of DNA and a sequence of keys production by a suggested Substitution box using 256 keys based on the quadratic map, logistic map, and Lorenz map that proves difficult to recover by any attack

show that the suggested system is substantially more dependable and resistant against various types of assaults than numerous other comparable speech signal encryption systems that have been developed in the past.
