A survey of Lightweight Cryptographic Hash Function

Abstract

Lightweight cryptography is developed to enhance the security level in pervasive computing applications such as those characterized by smart but resource-constrained devices. The two main primitives of lightweight symmetric cryptographic are lightweight block cipher and lightweight hash algorithm. In this paper, a comprehensive survey of some lightweight cryptographic hash functions will be described from both hardware and software perspectives. Apart from covering the analyses of these algorithms, the differences of these primitives in terms of throughput, number of cycle, comprehensive area, power and energy will be outlined. We will provide a classification of these lightweight hash functions as well
