Abstract:
This paper proposes the establishment of a secure encryption system for data transmission that includes three stages: first stage is a scrambling stage that is divided into scrambling of different sizes blocks and scrambling bits, the second stage is the use of DNA code to flip the bits and the third stage is the encryption using the Substitution box by 256 keys. The scheme is analysed using a variety of metrics. The findings demonstrate that the proposed system is significantly more reliable and robust against various forms of attacks than several recent related speech signal encryption systems.
