Radio Frequency Identification (RFID) is rapidly developing technology which has greatly revolutionized our lives around the globe. In RFID scheme, the most leading and foremost issue is of security and confidentiality. An efficient and successful way to provide secure transmission is to implement authentication protocols. Pseudorandom Number Generators (PRNGs) plays an important role for security which not simply introduces randomness but also strengthens the diffusion properties of protocols. Unfortunately, the existence of PRNGs in authentication protocols increases the size of the tag which ultimately boosts up the cost of those tags. In this paper, the efficient hardware implementation of numerous Lightweight PRNGs (Linear Congruential Generator, Linear Feedback Shift Register, AKARI-1, AKARI-2, Gold-code sequence generator) has been performed. Then a novel ultra-lightweight pseudorandom number generator ‘Extremely Lightweight PRNG’ (ELPRNG) using Recursive Hash has been proposed and optimally implemented. We have used XILINX Design suite for circuit synthesis and experimental results (for the targeted device virtex- 6). Experimental results show that proposed EL-PRNG requires fewer resources than its contending PRNG.
