METHOD AND SYSTEM FOR USING LOCATION INFORMATION ACQUIRED FROM GPS FOR SECURE AUTHENTICATION

摘要

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.

1. A method for processing data in a communication system involving a challenge, comprising:
receiving, by a first device, a first password from a second device in response to said challenge; determining, by said first device, whether said first password matches a second password that is unique per a location of a chip and per said challenge, said chip being integrated within said first device; and granting, by said first device, access to said second device to a secure function controlled by said first device when said first password matches said second password.
