Secure functions may be accessed via an authentication process utilizing a password that may be generated within a chip integrated on a device. The password may be unique per chip location, per challenge and/or per chip,. The location of the chip may be determined based on GPS information and securely stored and securely communicated to an external entity. Two or more of the chip location, a generated random number sample and a key from a table of keys may be passed to a hash function that may generate a password. An external entity attempting access may be challenged to respond with a password that matches the password generated by the hash function. The response may be compared with the password generated by the hash function and access to one or more secure functions may be granted based on the comparison. |
