Abstract
A computing device includes a processor and a machine-readable storage storing instructions. The instructions are executable by the processor to: receive a bit vector representing input data to be tokenized; divide the bit vector into two vector portions; and perform a plurality of rounds of a Feistel network on the two vector portions, each round including converting one vector portion using a table-based hash function that combines multiple tokens retrieved from at least one token table.
