RainHash2.0: Hardware- and Arithmetization-friendly Hash Function

Zero-knowledge (ZK) proof systems have developed rapidly in recent years, with hash functions as one of their central building blocks. Since these often dominate the prover cost, circuit-friendly hash function design has become an active research area. Most hash proposals target prime fields, although recent protocols...

BenX: Resource-Sharing Permutations for Computational Integrity

Cryptographic hash functions over integers modulo a prime play a decisive role in the efficiency and security of proof systems for computational integrity. Early designs focused on compact arithmetic circuits and efficient software execution, primarily targeting general-purpose CPUs rather than hardware accelerators. T...
