The SHA3-512 Cryptographic Hash Algorithm Analysis And Implementation On The Leon3 Processor

摘要

Embedded systems are computerbased systems designed to execute specific functions. Such a system is, in general, embedded as part or unit of a complete device in order to control, monitor, and facilitate its operation. An embedded system includes hardware and software parts with fixed or programmable capabilities. Thus, with the everincreasing role that software is playing in embedded systems, software performance is one of the embedded system implementation goals. In this paper, we consider the software cryptographic hashfunctions implementation on hardware platforms. In fact, Hash functions are used in several informationsecurity applications like message authentication codes, digital signatures, and other forms of authentication. In this work, we presented a detailed case study, including the SHA3512 algorithm analysis and implementation on the LEON3 soft core processor. The SHA3512 is programmed using the C language, and compiler optimization techniques are used to improve the efficiency of the obtained executable programs in order to be implemented on LEON3 using the ML507 Virtex5 Xilinx FPGA board.
