Parallelizing message schedules to accelerate the computations of hash functions. This paper describes an algorithm for accelerating the computations of Davies–Meyer based hash functions. It is based on parallelizing the computation of several message schedules for several message blocks of a given message. This parallelization, together with the proper use of vector processor instructions (SIMD) improves the overall algorithm’s performance. Using this method, we obtain a new software implementation of SHA- 2. ![]() Hyperlinked definitions and discussions of many terms in cryptography, mathematics, statistics, electronics, patents, logic, and argumentation used in cipher. BER for BPSK in OFDM modultion with a Rayleigh distributed channel of duration lower than the cyclic prefix. Matlab/Octave simulation scripts also provided. An American writer in Rome is stalked by a serial killer bent on harassing him while killing all people associated with his work on his latest book. Cycles/Byte on the second and 1. Cycles/Byte (for an 8 KB message) on the third Generation Intel\(^{\textregistered }\) Core\(^\mathrm{TM}\) processors. We also show how to extend the method to the soon- to- come AVX2 architecture, which has wider registers. Since processors with AVX2 will be available only in 2. Instead, we show that our resulting SHA- 2. SHA- 5. 12 implementations have a reduced number of instructions. Based on our findings, we make some observations on the SHA3 competition. We argue that if the prospective SHA3 standard is expected to be competitive against the performance of SHA- 2. Terramodel Command List (including TMLs) compiled by Geocomp Systems.SHA- 5. 12, on the high end platforms, then its performance should be well below 1. Cycles/Byte on the current, and certainly on the near future processors. Not all the SHA3 finalists have this performance. Furthermore, even the fastest finalists will probably offer only a small performance advantage over the current SHA- 2. SHA- 5. 12 implementations. Keywords. SHA- 2.
