An integrated circuit () is provided with function modules () which comprise a central processing unit () for treating data and executing a program and a cache memory (). Until now, it was complicated and costly to ensure the manipulation security of the modules. The function modules () comprise an encoding unit () for data encoding and decoding.

Arrangement comprising an integrated circuit

A data medium for identifying objects, in particular gas cylinders, includes a data source and an energy source. Each data medium contains at least one RF signal reflector having a characteristic frequency which can be controlled by the data source. The waveform of the characteristic frequency containing the individual identification of the data medium is in coded form. A scanning device for interrogation of the data medium and a process for controlling the data medium are also provided.
