Patent ID: 8255700

Claim:
A method of securing an electronic device, the method comprising: initializing the electronic device into a determinable disabled state to limit access to one or more secure locations of a plurality of secure locations within the electronic device; receiving an access key vector; and selectively initializing a test access state of the electronic device, wherein the selectively initializing the test access state of the electronic device includes: comparing the received access key vector to a stored access key; determining that the access key vector and stored access key have a predetermined relationship; implementing an internal reset for initializing at least one fuse to a logical state corresponding to a fuse state, wherein the logical state corresponding to the fuse state of the at least one fuse is either random, floating, or indeterminable prior to implementation of the internal reset; sensing the logical state corresponding to the fuse state of the at least one fuse; and enabling communication access to a decryption module and encrypted data within the electronic device based in part on the logical state corresponding to the fuse state of the at least one fuse, and based further in part on the determination that the received access key vector and the stored access key have the predetermined relationship.
