Performance evaluation of lightweight Block Ciphers in soft-core processor

The Internet of Things (IoT) and RFID devices are essential parts of the new information technology generation. They are mostly characterized by their limited power and computing resources. In order to ensure their security under computing and power constraints, a number of lightweight cryptography algorithms has emerged. This paper outlines the performance analysis of six lightweight blocks crypto ciphers with different structures - LED, PRESENT, HIGHT, LBlock, PICCOLO and TWINE on a LEON3 open source processor. We have implemented these crypto ciphers on the FPGA board using the C language and the LEON3 processor. Analysis of these crypto ciphers is evaluated after considering various benchmark parameters like throughput, execution time, CPU performance, AHB bandwidth, Simulator performance, and speed. These metrics are tested with different key sizes provided by each crypto algorithm.
