    As embedded systems play more and more important roles Internet of Things (IoT), the integration of cryptographic functionalities is an urgent demand to ensure data and information security. Recently, Keccak was declared as the winner of the third generation of Secure Hashing Algorithm (SHA-3). However, implementing SHA-3 on a specific 32-bit processor failed to meet the performance requirement. On the other hand, implementing it as a cryptographic coprocessor consumes a lot of extra area and requires customized driver program. Although implementing Keccak on a 64-bit platform is more efficient, this platform is not suitable for embedded implementation. In this paper, we propose a novel SHA-3 implementation using instruction set extension based on a 32-bit LEON3 processor (an open source processor), with the goals of reducing execution cycles and code size. Experimental results show that the proposed design reduces around 87% execution cycles and 10.5% code size as compared to reference designs. Our design takes up only 9.44% extra area with negligible speed overhead compared to the standard LEON3 processor. Compared to the existing hardware accelerators, our proposed design occupies only half of area resources and does not require extra driver programs to be developed when integrated into the overall system.
