Hash function requirements for Schnorr signatures

Journal of Mathematical Cryptology, 2009
We provide two necessary conditions on hash functions for the Schnorr signature scheme to be secure, assuming compact group representations such as those which occur in elliptic curve groups. We also show, via an argument in the generic group model, that

Development of a New Post-Quantum Digital Signature Algorithm: Syrga-1

Computers
The distinguishing feature of hash-based algorithms is their high confidence in security. When designing electronic signature schemes, proofs of security reduction to certain properties of cryptographic hash functions are used.

Advances in Hash Function Cryptanalysis

, 2012
When significant weaknesses are found in cryptographic primitives on which the everyday security of the Internet relies, it is important that they are replaced by more secure alternatives, even if the weaknesses are only theoretical.

spongent: A Lightweight Hash Function [PDF]

, 2011
This paper proposes spongent - a family of lightweight hash functions with hash sizes of 88 (for preimage resistance only), 128, 160, 224, and 256 bits based on a sponge construction instantiated with a present-type permutation, following the hermetic sponge strategy.

A chaotic parallel hash engine with dynamic stochastic diffusion for blockchain and cloud security

Scientific Reports
The design of cryptographic hash functions is crucial for ensuring the security of digital information. In this context, cellular automata (CAs) have emerged as a promising tool due to their inherent parallelism, determinism, and simplicity.
