Cryptology Transmitted Message Protection

The book "Cryptology Transmitted Message Protection" offers comprehensive methods for enhancing information security in protected communication systems. It combines interdisciplinary scientific engineering concepts, including cryptography, chaos theory, nonlinear and singular optics, as well as radio electronics. A central theme of the book is the use of optical vortices as carriers of information and the role of self-driven nonlinearity, which plays a crucial function in the development of security solutions. The approaches presented allow for a discussion of the phenomenon of deterministic chaos in the context of information security issues, illustrated by examples from electronic and optical systems. Additionally, vortex detectors and communication systems are addressed, and mathematical models of the chaos oscillator as encoders in synchronous chaotic communication systems are introduced, which are examined for their efficiency both analytically and experimentally. The book concludes with an analysis of the cryptological features of the systems studied and proposes new structures for secure communication.
