Enhancing the Security of Delayed Differential Chaotic Systems With Programmable Feedback

This brief introduces a delayed differential feedback chaos generator with a programmable feedback element. The programmable feedback allows us to implement an arbitrary nonlinearity or modulate the feedback delay time. Delayed differential feedback systems have been suggested for secure communicati...

Description
Summary:This brief introduces a delayed differential feedback chaos generator with a programmable feedback element. The programmable feedback allows us to implement an arbitrary nonlinearity or modulate the feedback delay time. Delayed differential feedback systems have been suggested for secure communications, and the flexibility of the programmable system is shown to enhance security against published cracking algorithms
