Abstract

A method for monitoring a network component. The network component performs a calculation checking the correct functionality of the network component using data which is specific to a state of the network component. The calculation result is transmitted to a monitoring device, which checks the state of the network component and the correct functionality of same using the transmitted calculation result. A request message with a parameter that is specific to the request is transmitted from the monitoring device to the network component, and the specific parameter is used by the network component in the calculation process. This enables the monitoring device to ensure that the result transmitted from the network component is actually up-to-date. Errors can be detected to the effect that a malfunction or a failure of the functionality of the network component has occurred.

Dependent claims

A method for monitoring a network component, the method comprising:

using the network component to carry out a calculation which checks a correct functionality of the network component using data that is specific to a state of the network component;
transmitting a calculation result from the network component to a monitoring device;
and
using the monitoring device to check the state of the network component and a correct functionality of the network component on a basis of the transmitted calculation result;
using the network component to carry out a calculation which checks the functionality of the network component by encrypting data that is specific to the state of the network component;
transmitting the encrypted data from the network component as a calculation result to the monitoring device;
checking with the monitoring device the state of the network component and the encryption performed by the network component based on the transmitted calculation result;
transmitting a request message from the monitoring device with a test key that is specific to the respective request message to the network component;
and
encrypting with the network component the data that is specific to the state of the network component for ensuring that the calculation status is up to date by means of the test key.
