摘要:
In one embodiment, a mechanism for string hashing using a random number generator is disclosed. In one embodiment, a method includes dividing an input stream provided to a hashing module into a plurality of subsets of ‘n’ bits, entangling, by a mixer of the hashing module, one of the subsets of ‘n’ bits by a next sequential output of a pseudo-random number generator (PRNG), adding a product of the entangling to an accumulator of the hashing module, repeating the entangling and adding until all subsets of the plurality of subsets have been processed, and returning a value in the accumulator as a hash result value.
