ABSTRACT:
In order to protect secret information in the electronic storage medium, the storage medium is provided in a housing protected against access. This housing contains one or more detector elements, via which erasure of the memory contents is initiated when unauthorized access is detected. The detector elements are connected with a clock unit which sets these elements into operation for short periods of time at certain time intervals. This clocked operation allows for the energy consumption of the overall arrangement to be reduced many times over without any essential restriction of security.
