ABSTRACT:
A coding device for implementing a cryptographic encryption and/or access authorization includes a data processing unit, a decoupling unit, a power supply interface, a main clock supply unit, and a power profile generator generating a power profile and superimposing it on a power profile of the data processing unit to prevent an attack by correlation analysis of the power profile.
