The SANDstorm hash[1] is a cryptographic hash function designed in 2008 by Mark Torgerson, Richard Schroeppel, Tim Draelos, Nathan Dautenhahn, Sean Malone, Andrea Walker, Michael Collins, and Hilarie Orman for the NIST SHA-3 competition.
The SANDstorm hash was accepted into the first round of the NIST hash function competition, but was not accepted into the second round.[2]
Architecture
[edit | edit source]The hash function has an explicit key schedule.[3] It uses an 8-bit by 8-bit S-box.[3] The hash function can be parallelized on a large range of platforms[which?] using multi-core processing.[4]
Both SANDstorm-256 and SANDstorm-512 run more than twice as slowly as SHA-2 as measured by cpb.[3][clarification needed]
As of 2009, no collision attack or preimage attack against SANDstorm is known which is better than the trivial birthday attack or long second preimage attack.[3]
