A consumable component apparatus including a receptacle region for receiving configured to receive a substance or material which is consumed under the control of a consumer device, an authentication circuit configured to authenticate the consumer device, and a switch coupled to the authentication circuit. The authentication circuit is configured to control the switch in such a way that the consumable component apparatus is activatable only if the consumer device is authenticated by means of the authentication circuit, and that the consumable component apparatus is deactivated if the consumer device is not authenticated by means of the authentication circuit.

Consumable component apparatus

A chip card sleeve including a cavity for holding a chip card, and a first contact and a second contact that extend into the cavity, wherein the first contact and the second contact are electrically conductively connected to one another.

A system and method for controlling a device. Data that was encrypted using a first encryption scheme is decrypted, then re-encrypted using a second encryption scheme. The re-encrypted data is then decrypted.

Method and system for controlling a device

An apparatus for checking an error detection functionality of a data processing circuit, comprising an arithmetic logic unit, which provides an output datum based on an input datum, and an error detection circuit that executes the error detection functionality and detects an error based on the output datum during correct execution of the error detection functionality, and generates an error signal, if an error is present, which comprises a control circuit that passes the error signal through to an error signal output in a normal operating mode, and blocks the error signal in a checking mode, does not let the error signal pass to the error signal output, influences the arithmetic logic unit, the error detection circuit or the input datum such that the error detection circuit detects an error during correct execution of the error detection functionality, and, if no error signal is received in response to influencing, outputs an alarm signal indicating an incorrect execution of the error detection functionality.

Apparatus and method for checking an error detection functionality of a data processor

A chip including a processor for performing a predetermined operation, a provider for providing a clock signal, with which the processor is clocked, a counter for decrementing or incrementing a count based on the clock signal, a monitor for signaling the predetermined operation to be prevented, depending on the count, and a non-volatile storage for non-volatily storing the count.

Protection of chips against attacks

Methods and systems for transferring information to a device include assigning a unique identifier to a device and generating a unique key for the device. The device is located at a first site, and the unique identifier is sent from the device to a second site. The unique key is obtained at the second site, and it is used for encrypting information at the second site. The encrypted information is sent from the second site to the device, where it can then be decrypted.
