Special Issue Information

Dear Colleagues,

The research on the applications of chaotic systems in security-related applications is active and constantly expanding. Researchers are using chaotic systems as a light source of pseudo-randomness in order to increase the complexity of a design, and protect it against adversaries. This refers to any situation where information must be kept or transmitted in a secure way.

The aim of this Special Issue is to advance the developments on security-related applications of chaotic systems. The topics span any research related to addressing the use of chaotic systems in information masking, encryption, cryptanalysis, secure communications, as well as hardware implementations of the above. Potential topics include the following:

- Continuous, discrete, fractional order, or quantum chaotic systems;

- Encryption of any type of data, like image, text, speech, or biomedical data;

- Random number generators;

- Watermarking;

- Compressed sensing;

- Secure communications;

- Any other security application in engineering and communications;

- Hardware implementations of the above.

Abstract

This paper presents a chaotic system based on novel semiconductor nanolasers (NLs), systematically analyzing its chaotic region and investigating the influence of key parameters on the unpredictability of chaotic output. This study found that under optical feedback conditions, NLs generate chaos across a wide range of feedback parameters, with the highly unpredictable region completely overlapping with the chaotic region. Further injection into the slave lasers enhances the chaotic output, expanding the range of unpredictability. Additionally, we analyzed the impact of internal parameter mismatch on the complexity of chaotic signals and found it to be similar to the scenario when parameters are matched. Using this chaotic system as an entropy source, we constructed a random number generator (RNG) and investigated the effects of internal parameters mismatch and differences in the injection parameters on the generator’s performance. The simulation results show that the RNG performs well under different parameter settings, and the generated random sequences pass all random number tests successfully. Therefore, this chaotic system can yield a high-complexity chaotic light source with appropriate parameter selection, and when combined with effective post-processing, it can generate high-quality random numbers. This is crucial for advancing the realization of small-sized, high-randomness RNGs. Full article
