Abstract
A secure computing device having a storage arrangement configured to store a secret. The secure computing device includes a first interface configured to control a display, and a second interface configured to receive an input signal having information which reproduces a prompt to display the secret. The secure computing device is designed to read the secret from the storage arrangement on the basis of the input signal, and to control the display via the first interface in such a way that a display of the secret is effected.
Claims20
A secure computing device, comprising:
- a storage cluster configured to store a secret;
- a first interface configured to send a control signal to control a display;
- a second interface configured to receive an input signal having information which causes a prompt to display the secret;
- a third interface configured to receive a program code to run a computer-implemented application,
- wherein the secure computing device is configured to store the program code in the storage cluster, to read the secret from the storage cluster based on the input signal, and to control the display via the first interface such that a display of the secret is effected;
- and
- a switch coupled between the first interface and the display, wherein the secure computing device is configured to control the switch such that the switch connects the first interface to the display to enable display of the secret, and disconnects the first interface from the display to prevent display of the secret even when the first interface would have otherwise sent the control signal.
