Architecture

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]
