Design of Hybrid True Random Number Generator for Cryptographic Applications

In real-time applications, unpredictable random numbers play a major role in providing cryptographic and encryption processes. Most of the existing random number generators are embedded with the complex nature of an amplifier, ring oscillators, or comparators. Hence, this research focused more on implementing a Hybrid Nature of a New Random Number Generator. The key objective of the proposed methodology relies on the utilization of True random number generators. The randomness is unpredictable. The additions of programmable delay lines will reduce the processing time and maintain the quality of randomizing. The performance comparisons are carried out with power, delay, and lookup table. The proposed architecture was executed and verified using Xilinx. The Hybrid TRNG is evaluated under simulation and the obtained results outperform the results of the conventional random generators based on Slices, area and Lookup Tables. The experimental observations show that the proposed Hybrid True Random Number Generator (HTRNG) offers high operating speed and low power consumption.
