Description
Summary:The Internet of Things today is in all areas of daily life. It changes all sectors including industry, agriculture, and smart homes. Therefore, IoT devices require secure microprocessors for data security. However, these devices are limited in terms of computing power, surface, memory, and in terms of energy consumption. In this article, we will present a new customized version of LEON3, the RISCV (Reduced Instruction Set Computer-five) processor, dedicated to IoT applications with a powerfully built security mechanism integrated at the design stage. Also, we presented the proposed lightweight cryptographic algorithm instructions (LED and SIMON), which are integrated into the new architecture of the ReonV processor. After integrating the lightweight encryption instructions to ensure security, we have implemented our custom processor on FPGAs and are evaluated for slice LUT plus FF pairs and frequency. The obtained results show that our proposed designs can achieve good encryption results with high performance and low cost for our new RenoV processor architecture Compared to previous works.
