Efficient Pipelined Hardware Implementation of RIPEMD-160 Hash Function

In this paper an efficient implementation of Ripemd160 hash function is presented. Hash functions are a special family of cryptographic algorithms, which is used in technological applications with requirements for security, confidentiality and validity. Applications like PKI, IPSec, DSA, MAC’s incorporate hash functions and are used widely today. The Ripemd-160 is emanated from the necessity for existence of very strong algorithms in cryptanalysis. The proposed hardware implementation can be synthesized easily for a variety of FPGA and ASIC technologies. Simulation results, using commercial tools, verified the efficiency of the implementation in terms of performance and throughput. Special care has been taken so that the proposed implementation doesn’t introduce extra design complexity; while in parallel functionality was kept to the required levels. Keywords—Hardware implementation, hash functions, Ripemd160, security.
