Özet:

A hardware implementation of a quadratic map through FPGA platform is proposed in this paper. Firstly, a chaotic quadratic map is modeled by using Matlab/Simulink programming and then implemented into the FPGA (Field Programmable Gate Array) to be used for key generation for cryptographic applications. When the quadratic map is in chaotic mode, its output is unpredictable and aperiodic. Besides this, the map has a uniform output distribution and sufficient randomness. These characteristics make the chaotic quadratic map a suitable key generator for cryptography. This paper also reveals the successful real-time implementation of the quadratic map using FPGA for practical applications. Experimental results confirm that the feasibility of the quadratic map is verified under a digital hardware environment.
