System and techniques for secret key transfer in benefit denial system

An electronic device comprising:

• a functional component for performing at least one function of the electronic device;
• a first power source adapted to be coupled to the functional component to power the at least one function of the electronic device;
• and
• a benefit denial element comprising:
• a memory adapted to store a first device key;
• a communication element for communicating with a second electronic device to receive a command and information indicative of whether the second electronic device has access to a second device key;
• and
• an interruption element coupled functionally between the first power source and the functional component, the interruption element configured to selectively disable or enable the at least one function of the electronic device in accordance with a received command upon determining that the second electronic device has access to the second device key and that the second device key matches the first device key.

A method for providing selective benefit denial in an electronic device equipped with at least one functional component for performing one or more functions of the electronic device, comprising:

• storing, in a secure memory of the electronic device, a first device key specific to the electronic device;
• receiving, via a communication element of the electronic device from a second electronic device, a command and information indicative of whether the second electronic device has access to a second device key;
• determining, by a benefit denial element of the electronic device coupled to the communication element, whether the second electronic device has access to the second device key and whether the second device key matches the first device key if the second electronic device is determined to have access to the second device key;
• and
• disabling or enabling the one or more functions of the electronic device based on the command if the second device key matches the first device key, and not complying with the command if the second device key does not match the first device key.

A benefit denial system comprising:

• an electronic device including a functional component for performing a function of the electronic device;
• a first power source adapted to be coupled to the electronic device to power the function of the electronic device;
• and
• a denial element coupled functionally between the functional component of the electronic device and the first power source when the first power source is coupled to the electronic device, the denial element comprising:
• a communications element for receiving at least one command and authorization information from a second electronic device;
• and
• an interruption element coupled functionally between the functional component and the first power source, the interruption element configured to selectively disable or enable the function of the electronic device based at least in part on the authorization information and the at least one command;
• a processor;
• and
• a non-transitory computer-readable medium including instructions that, when executed by the processor, cause the processor to at least:
• receive the at least one command from the second electronic device;
• receive information indicative of whether the second electronic device has access to a device key associated with the authorization information from the second electronic device;
• determine a validity of the device key by comparing the received device key with a stored device key;
• and
• upon determining the device key is valid, execute the at least one command to cause the interruption element to disable or enable the function of the electronic device based on the command.
