Abstract

Security and trust of data transmission between IoT equipment’s continues to be a major challenge in the advancement of IoT technology. To resolve these issues, a low-power and low-cost RISC-V processor optimized for IoT applications is presented in this paper. An Advanced Encryption Standard (AES) Encrypt Accelerator is built into the processor to provide fast and secure transmission of data. AES being a symmetric encryption standard makes a good trade-off between high-speed computing, secured encryption system and key management simplicity, and is best suitable for resource-constraint IoT devices. The RISC-V processor and the AES encryption accelerator are developed in the Verilog HDL and realized both on the Xilinx FPGA platform and in ASIC technology. The presented processor and encryption accelerator are realized with Verilog HDL under the guidelines of low power and area cost. The simulation results show that the proposed architecture achieves higher security in encryption and better key management in terms of power and the delay degradation is acceptable. This makes it an ideal solution for future IoT applications that need more sophisticated data protection.
