Abstract:
1. A method comprising: receiving an authentication challenge from an entity, the authentication challenge comprising an accumulator with an initial value, lists of elements in a shared table, a list of sorting algorithms, and an order in which the list of sorting algorithms are to be performed, each sorting algorithm in the list of sorting algorithms being associated with one of the lists of elements and modified to include embedded instructions operating on the accumulator; generating a temporary table for each list of elements in the shared table by copying elements from the shared table as indicated in each list of elements, each temporary table having an associated sorting algorithm from the list of sorting algorithms; sorting each temporary table with the associated sorting algorithm, thereby updating the accumulator with the embedded instructions by chaining a result of each associated sorting algorithm according to the order to yield an updated accumulator; and transmitting the updated accumulator to the entity for authentication.
