Authentication device, mobile terminal, and authentication method |
摘要 |
<p>The security of an IC card is improved by managing success and failure in authentication individually for each terminal program. An IC card includes a random number generation section, a source authentication section, and a process execution section. Upon receipt of a message of type "I", the random number generation section generates a random number n, and stores it in a random number storage section by associating the random number n with a source included in the message. Upon receipt of a message of type "2" from the source and in a case where the random number n corresponding to the source is stored, the source authentication section collates a value m calculated from an authentication key held by the IC card and the random number n with a value m included in the message of type "2". When both values agree, upon receipt of a message of type "3" from the source, the process execution section executes a process in accordance with a type of the message.</p> |
