Method for protecting a security module and arrangement for the implementation of the method

Image Number 3 for United States Patent #6954149.

In a security module and a method for protecting a security module, wherein security-relevant data are stored in a memory in the module, proper insertion of the security module on a device motherboard is monitored with a first function unit and a second function in the security module. The first function unit signals the status of the security module. The second function unit detects improper use or improper replacement of the security module, and upon detection of improper use or improper replacement, the second function unit causes the security-relevant data to be erased.
