Authentication System, CE Device, Mobile Terminal, Key Certificate Issuing Station, And Key Certificate Acquisition Method |
摘要 |
Provided is an authentication system for improving user-friendliness. An IC card (100) of the authentication system (10) includes: a key/certificate storage unit (120) connected to a terminal device (200) and capable of storing a key pair and a temporary certificate or a permanent certificate while correlating them; a CE temporary public key certificate acquisition unit (170); and a CE public key/certificate acquisition control unit (150) connected to a CE device (300). When the key/certificate storage unit (120) has a key pair not correlated either to a temporary certificate or a permanent certificate, the CE temporary public key certificate acquisition unit (170) acquires a temporary certificate corresponding to the key pair from a public key certificate issuing station (400) by using the mobile terminal (200) and causes the key/certificate storage unit (120) to store it. When the key/certificate storage unit (120) has a key pair correlated a temporary certificate but not to a permanent certificate, the CE public key/certificate acquisition control unit (150) acquires a permanent certificate from the public key certificate issuing station (400) by using the temporary certificate via the CE device (300) and causes the key/certificate storage unit (120) to store it.
