Abstract
A method and apparatus for protecting electronic devices from cloning employs an electronic signature generated from an identification code for the electronic device (e.g., an electronic serial number (ESN), an international mobile equipment identifier (IMEI), or the like) and a unique, unchangeable identification for a hardware component of the electronic device code (e.g., a flash hardware serial number, or the like). The electronic signature is encrypted and stored to the non-volatile memory of the electronic device for verifying the authenticity of the electronic device's identification code to prevent use of the device for cloning a second electronic device.
