Abstract

PURPOSE: The key input information is fed into 1st register, and output of 1st register is fed into 2nd register. Then, comparison is carried out between key input information and output of 1st register and between output of 1st and 2nd registers. In this way, the key input can be discriminated, effectively preventing malfunction.
