Skyscraper: Fast Hashing on Big Primes

Transactions on Cryptographic Hardware and Embedded Systems
Arithmetic hash functions defined over prime fields have been actively developed and used in verifiable computation (VC) protocols. Among those, ellipticcurve- based SNARKs require large (256-bit and higher) primes. Such hash functions are notably slow,
