FPGA Hardware Co-simulation of New Chaos-Based Stream Cipher Based on Lozi Map
FPGA Hardware Co-simulation of New Chaos-Based Stream Cipher Based on Lozi Map is a scholarly work, published in 2018 in ''International Journal of Engineering and Technology''. The main subjects of the publication include stream cipher, CHAOS, cryptography, cellular automaton, computer hardware, parallel computing, chaos theory, embedded system, field-programmable gate array, and computer science. A novel stream cipher based on chaotic synchronization is presented in this paper, a simple and effective technique is used for this purpose; it consists of feeding back the ciphertext to the cryptosystem and incorporates it on the driver signal for synchronization.Simulation results showed that the proposed stream cipher (PSC) has good confusion/diffusion properties and provide a strong key.The performed statistical and security analysis on the PSC confirms its feasibility for security purposes.The hardware-in-the-loop co-simulation over Xilinx XC6SLX45 FPGA of the PSC is provided, where a clock frequency of 50.24MHz is achieved corresponding to high throughput of 2.51 Gbps.The obtained results make the PSC suitable for nowadays needs of secure and robust crypto-systems.
