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

open access: yesJournal 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 ...

A trapdoor one-way function for verifiable secret sharing

open access: yesHigh-Confidence Computing, 2022
This paper proposes a (t,n)–threshold verifiable secret sharing scheme with changeable parameters based on a trapdoor one-way function. This scheme consists of a generation phase, a distribution phase, an encoding phase and a reconstruction phase.

Cryptographic Hash Functions: Theory and Practice [PDF]

open access: yes, 2010
Cryptographic hash functions are an essential building block for security applications. Until 2005, the amount of theoretical research and cryptanalysis invested in this topic was rather limited. From the hundred designs published before 2005, about 80% was cryptanalyzed; this includes widely used hash functions such as MD4 and MD5.
