QCA Technology Based 8-Bit TRNG Design for Cryptography Applications

Abstract

Hardware Security is very important considering the extensive usage of hardware devices and data security. In this paper, the structure of a hardware security primitives namely the True Random Number Generator (TRNG) is proposed using Quantum Cellular Automata (QCA) technology. The AND gate, XOR gate and a gate with irregular behavior are used to generate random output depending upon the metastability of the QCA structure. Furthermore, the structure is cross looped and asymmetrically inverted for extra randomness. The energy calculations of the structure were performed using QCA Designer Pro and the randomness of the output was tested in the NIST Test Suite. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
