Efficient Hardware/Software Partitioning of Grøstl Algorithm

Nowadays there has been a surge in moderndecentralized information systems and networks based onthe blockchain technology. These systems are increasinglybecome popular and exploited in wide range ofapplications. Cryptocurrencies, decentralized systems ofdifferent functional tasks, like, key certification centers,distributed decentralized networks of electronicidentification and electronic voting, information systemsare different applications of blockchain technologies. Thiswork mainly focused on the Grøstl cryptographic hashfunction as one which is used in blockchain systems.Vivado tools for generating the IP of the Grøstl algorithmare used. Vivado HLS for high level synthesis and Vivadodesign suite for both importing the HLS IP and alsocreating the HDL IP. The implementation results indicatethat the number of resource usage (LUT/FF) and powerconsumption of the proposed structure is equal to(۳۸۸۳/۲۶۵۲) and ۰.۷۵۹(W) respectively. Moreover, thehash rate of the implemented structure is equal to ۱۴MHash/s.
