SHA-3 on ARM11 Processors

Anais do XIV Simpósio Brasileiro de Segurança da Informação e de Sistemas Computacionais (SBSeg 2014), 2012
This paper presents high-speed assembly implementations of the 256-bit-output versions of all five SHA-3 finalists and of SHA-256 for the ARM11 family of processors. We report new speed records for all of the six implemented functions. For example our implementation of the round-3 version of JH-256 is 35% faster than the fastest implementation of the ...

A new design paradigm for provably secure keyless hash function with subsets and two variables polynomial function

Journal of King Saud University: Computer and Information Sciences, 2022
Provably secure keyless hash function uses Random Oracle (RO) or Sponge principles for the design and construction of security-centric hash algorithms. It capitalizes the aforesaid principles to produce outcomes like MD2, MD5, SHA-160, SHA-224/256, SHA ...
