Abstract
An authentication apparatus of embodiments has a counter circuit and a pseudo-pass generating circuit. The counter circuit counts the number of times an inputted cryptographic key and a cryptographic key set in advance consecutively do not match. The pseudo-pass generating circuit outputs a pseudo-pass response when the number of times the keys consecutively do not match, which is counted by the counter circuit, exceeds a predetermined value.
