SYSTEM AND METHOD FOR SECURE AUTHENTICATION OF A "SMART" BATTERY BY A HOST

摘要

Systems and methods for providing a battery module 110 with secure identity information and authentication of the identity of the battery 110 by a host 120. In one embodiment, the system for providing a battery module with secure identity information includes: (1) a tamper resistant processing environment 200 located within the battery module 110 and (2) a key generator configured to generate a key based on an identity of the battery module 110 and cause the key to be stored within the tamper resistant processing environment 200.

主权项

1. A process of authenticating a battery, comprising:
(a) retrieving a first identity key in a battery powered device coupled to the battery; (b) generating a random challenge in the battery powered device; (c) retrieving a second identity key from a private memory of the battery; (d) combining the second identity key and the random challenge into a first response in the battery; (e) combining the first identity key and the random challenge into a second response in the battery powered device; (f) sending the first response from the battery to the battery powered device; (g) authenticating the battery by comparing the first response with the second response in the battery powered device; and (h) if the first response and second response results a match, authenticating the battery and enabling operation of the battery powered device.
