The fast evolution of digital technology has brought in an era where security is not negligible, especially in the world of the embedded systems. As Cyber threats are always more sophisticated, the demand for robust cryptography solutions is increasingly high. In this context, the RISC-V instruction set architecture (ISA), with its open-source form and modular design, presents a fertile ground that it is perfect for the future development. RISC-V has started in 2010, from the Parallel Computing Laboratory at the University of California, Berkeley, under the leadership of Professor David Patterson. RISC-V ISA is completely free and open-source, and It is based on the Reduced Instruction Set Computer (RISC) principles.
