(EN) Cryptographic device with a display means for identification of a defective function in the cryptographic device
Abrégé
(EN)

A cryptographic device for use with a data terminal in a data network contains here a transmission channel (S) and a reception channel (E) with associated cryptogenerators and data input and output equipment, as well as a control device (C) for controlling the reception and transmission channels. Associated with the control device (C) is an internal monitoring device (UA) for independent monitoring of the cryptographic device functions, with a display means (A) being linked to the monitoring device UA), which display means is used to identify a defective function in the cryptographic device by alphanumeric representation of information about the defective function.
