Abstract
The invention relates to an authentication system having a security apparatus which can check all three authenticating factor types for authentications (personal subject matter, secret, biometric characteristic), having an authorizing device and having a certifying institution, in which case their private keys, the public keys on the subscribing authorizing devices and the public keys of the connected users can be stored in this certifying institution. Furthermore, authentication means are provided there, by means of which an appropriately coded report can be produced, which can be passed via the authorizing device to the user. The user decodes this message and transmits the resultant authorization code via the authorizing device to the certifying institution. After checking the code in this certifying institution, a response which comprises confirmation or rejection is transmitted to the authorizing device.
