Abstract
Input data can be split into data components that can each have a length equal to a machine word size of a processor capable of parallel processing. Hash components can be selected to have a length equal to the length of the data components. A bitwise hashing function can be performed, in which each data component is hashed with a respective different one of the hash components. A representation of the hash components can be output as the hash. The bitwise hashing function can include an exclusive-or operation and a multiplication and can be a modified Fowler-Noll-Vo hashing function, such as a modified FNV-1a function.
