Use of Commutativity for Cryptology in Secret Communication
This addresses secure communication challenges in cryptology, though it appears incremental as it extends existing commutativity concepts to a new application area.
The paper introduces a novel application of commutativity in system design for secret signal transmission, presenting an original cryptology method validated through illustrative examples and Matlab Simulink simulations.
Commutativity of subsystems in cascade connected forms to form larger systems gets worthy to improve noise disturbance properties, stability, robustness and many other properties in system design. In this paper, another benefit of commutativity property is indicated, as far as the author knowledge for the first time, and illustrated by examples. This benefit is the gain of a new and original method for transmission of secret signals when travelling in a transmission channel. Hence, the paper presents an original and alternative method in cryptology. Their results are all validated by illustrative examples and Matlab simulation toolbox Simulink.
