Abstract
A testing method for verifying keys uses a dataset of integers, the dataset being previously split into subsets of the integers, each subset of the integers having a product data structure for a product of the integers in the subset. Each ordered pair of subsets in the dataset has a remainder data structure for factors of the integers in the subsets of the ordered pair. The method includes creating a subset including integers to be added to the dataset of integers, and generating a product data structure for the created subset, the product data structure based on computing a product of the integers in the created subset. The method also includes identifying distinct ordered pairs of subsets, each distinct ordered pair of subsets including a subset from the dataset and the created subset.
