SBIR-STTR Award

LIT proposes development of PUF Technology with improved entropy, variation, and noise characteristics. This technology holds promise for verifying the configuration of secure systems and verifying that the configuration has not been tampered with. This concept provides a new capability for verifying and authenticating hardware. In order to be effective for all AT applications, PUF responses must exhibit a unique result for each unit tested, exhibit a consistent result each time the same unit is tested, and provide as many effective bits of accuracy as possible.

Lit’s Puf Design Does Not Require Critical Component Placement And Routing Outside Of The Chip Operation And Is Capable Of Verifying And Monitoring An Entire System. Also, Han

LIT accomplished all Phase I goals and technical objectives. In Phase I LIT produced an effective Random Number Generator (RNG) and tested two PUF designs. The PUF designs showed greatly improved Entropy and Stability over other technologies. LIT’s Entropy Goal for Phase II is 100% (already proven by analysis) and the Stability goal is one bit error per million bits. In Phase II LIT will mature this PUF technology by producing 3 programmable logic IP Blocks: Asymmetric PUF (APUF), Memory Authentication Parameter Sensor (LIT’s memory incorporating PUF), and a Random Number Generator. LIT partner Lockheed Martin Mission Systems and Signals will test the IP Blocks (Cores) in tactical hardware to achieve TRL 8. LIT will produce interface software to use with the PUF cores allowing a customer to access, test, evaluate, and characterize the PUF performance in their application. LIT is producing a PUF test suite to accumulate and process test results in order to quantify Variation, Entropy, and Stability metrics. At the end of Phase II LIT will provide two licenses for each PUF core and provide 2 day training on the use of the IP Blocks and related tools.
