Abstract
A method and apparatus for initiating a zeroization process in an electronic device is provided. Diagnostic information is provided by a plurality of sub-systems such that when one or more conditions are detected that are expected to cause the electronic device to experience a failure in the near future or if the electronic device appears to have been compromised, then the zeroization process is triggered.
Claims36
A method for initiating a zeroization process in an electronic device, the method comprising:
- monitoring for the occurrence of a trigger condition during operation of the electronic device;
- determining whether at least one of a plurality of trigger conditions has occurred;
- and
- initiating the zeroization process in the electronic device in response to determining whether at least one of a plurality of failure conditions has occurred.

An electronic device for triggering zeroization comprising:
- a plurality of sub-systems a portion of which may store sensitive information in a memory;
- a monitoring module for monitoring diagnostic information from each sub-system;
- and
- a zeroization initiation circuit for activating a scrubbing routine to immediately delete sensitive information in response to said monitoring module detecting a trigger condition.

An electronic device comprising:
- a processing system including a processor and memory containing sensitive information;
- means for monitoring occurrence of a trigger condition during operation of the electronic device;
- means for determining whether the trigger condition has occurred;
- and
- means for triggering zeroization of sensitive memory in the electronic device when a trigger condition has occurred.
