In recent years, there are numerous studies on chaotic systems with special equilibrium
curves having various shapes such as circle, butterfly, heart and apple. This paper describes …

Audio piracy in the real-time transmission has intensified with digital replication and
distribution, making unauthorized sharing effortless and widespread, leading to a significant …

In this work, we have realized an efficient implementation of stream cipher algorithm for
speech data encryption and decryption. The design consists of a 128-bit non linear feedback …

Encryption plays a major role in achieving privacy, especially in communications and
information systems such as military systems, banks, telecommunications and individuals …

In this communication, we propose a stream cipher system based on nonlinear filter
generator for speech data encryption. The cipher is simple and highly efficient. It is …
