Abstract

Product Authentication protects the CPI through the Weapon System Life Cycle. LIT Product Authentication is structured into two major components. The Product Authentication Key System (PAKS ) derives cryptographic keys from authentication codes provided by the Product Authentication Sensor System (PASS ). Equipment lost or compromised is protected from reverse engineering since any effort to open the package or probe the electronics will result in production of an invalid cryptographic key. LIT Zero Power/Ultra Low Power sensors provide tamper detection and documentation while the product is unpowered. The system is capable of deriving a unique key based on physical attributes. Methods of detecting static keys are useless because there are none. PASS coupled with PAKS defeats methods of detecting derived keys since any methods of detecting the key, changes the key. Circuit changes and probing cause significant changes to the Sensor output which changes the derived key. In Phase II, LIT will develop a Product Authentication Demonstration Platform (PADP) to develop, test, and demonstrate the PASS concept. The PADP will also serve as a demonstration unit. LIT will produce PADP software to use to facilitate testing, to exercise the PADP, and to demonstrate LIT AT products to potential users.
