Abstract
New tokenization tables are derived at intervals in order to increase the security of tokenized data that is transferred between two endpoints. Generation of the new tokenization tables is based on previous tokenization tables, which advantageously allows the generation process to be performed locally at the two endpoints independently of an external tokenization table provider. New tokenization tables can periodically be distributed to the endpoints as a new starting point for derivation.
