Abstract
Systems, methods, and apparatuses are described for generating deterministic crypto-random values for cryptographic operations such as tokenization. A computing device may receive a plurality of unique character strings by receiving such strings from a server and/or by generating such strings based on a seed value. The computing device may define a seed table comprising a plurality of rows and a plurality of columns such that each row of the plurality of rows corresponds to a different character of the set of characters and each column of the plurality of columns corresponds to a different character of a unique character string, of the plurality of unique character strings, corresponding to the different character. The table may be expanded by processing sequential rows of the seed table to generate a tokenization table. That tokenization table may be used to generate tokenized versions of input data.
