Cryptographic coprocessor for data integrity algorithms

In cryptography, for message/data integrity assurances, that are vital for a security product, are used Hash functions. The Hash algorithm is based on a one-way-function that maps an arbitrary-length data to a fixed-length output. This paper will present the usage of the newest hash algorithm SHA-3 - Keccak into an electronic module based on FPGA. This will work, along with an ARM Cortex-A9 microprocessor, as a cryptographic coprocessor. The implemented hardware solution significantly increased the computational speed of the signal data processing.
