Data security is essential for the proliferation of the Internet of things and cyber-physical system technologies. Data security can be efficiently achieved by incorporating lightweight cryptography techniques. In this study, a set of highperformance hardware architectures for PRESENT lightweight block cipher are proposed that perform encryption, decryption and integrated encryption/decryption operations. Datapath of the architectures is of 64 bit width that supports standard 80 and 128 bits key lengths. The architectures are synthesised on Xilinx Virtex-5 XC5VLX110T (ff1136-1) field-programmable gate array device of ML-505 platform. To perform functional verification, a large number of test vectors are used. Performance measurement is performed by evaluating maximum frequency, throughput, power dissipation and energy consumption. Experimentally, it is found that the proposed architectures are resource-efficient, high-performance and suitable for lightweight, latency-critical and low-power applications in comparison with existing architectures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
