摘要

PROBLEM TO BE SOLVED: To provide a simple and secure authentication method based on addition and multiplication.;SOLUTION: An authentication method comprises a step of generating plural temporary keys by random numbers to create a temporary key array comprising the plural temporary keys, a step of generating plural integers which are set to row numbers and column numbers ("first address") of the temporary key array by random numbers, a step of calculating pluralities of row numbers and column numbers in a temporary key acquisition array based on a personal key PK, a step of acquiring pluralities of row numbers and column numbers ("second address") in the temporary key array stored in the row numbers and column numbers (plural sets) in the temporary key acquisition array calculated based on the personal key PK, and a temporary key acquisition step of acquiring plural temporary keys stored in the second address in the temporary key array.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
