Cryptographic device with a display means for identification of a defective function in the cryptographic device
First Claim
1. A unitary cryptographic device for use with a data terminal (DEE) in a data network, havinga transmission channel (S) with associated transmission cryptogrnerator (KG-S) for encoding transmitted data and corresponding data input and output equipment (DE,DA),a reception channel (E) with associated reception cryptogenerator (KG-E) and corresponding data input and output equipment (DE, DA),a control device (C) for controlling the reception and transmission channels (S, E),an internal monitoring device (UA) assigned to the control device (C) for independent monitoring of the cryptographic device functions, anda display means (A) linked to the monitoring device (UA) for identification of a defective function in the cryptographic device by alphanumeric representation of information about the defective function.

Abstract
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.
