Abrégé
(EN)

The invention concerns a cryptographic device for use with a data terminal in a data network. The cryptographic device includes a transmission channel (S) and a reception channel (E) with associated crypto generators and data-input and output equipment, as well as a control device (C) for control of the reception and transmission channels. Associated with the control device (C) is an internal monitoring device (UV) for independent monitoring of the cryptographic device functions, a display (A) being linked to the monitoring device (UA). The display is used to identify a faulty cryptographic device function by presenting, in alpha-numeric form, information on the faulty function.
