Abstract

A configuration including, in authentication contexts, function unit identification information unique to the function unit that has executed an authentication subprocess in entity devices permits an authentication apparatus to specify the function unit that has executed the authentication subprocess in the entity devices. The verifier, therefore, can verify the legitimacy of the authentication subprocess from the authentication context even in the presence of a plurality of function units capable of executing the same authentication subprocess in the entity devices.
