  • Method for protecting a data memory
    Patent number: 7039815
    Abstract: A method for protecting a security data memory is described wherein external action on a component containing the security data memory is detected by sensors. Overshooting of a threshold on one of the sensors causes an attack to be signaled by reason of which the content of the security data memory is at least partly erased. The status of the sensors is permanently monitored and the status data of the sensors recorded.
