GRAMMATECH INC — Department of Defense SBIR Phase I: Physically Unclonable Devices (PUFs) have many applications in security and digital rights

Description

Physically Unclonable Devices (PUFs) have many applications in security and digital rights management. These devices are used in creation of random number generators used to seed key generation and one-time pad construction for encryption applications. They are also used as a means of uniquely authenticating a piece of hardware or computing device. Given the large applicability of field programmable gate arrays (FPGAs), it is desirable to have PUFs that can be applied to these commercial devices. However, existing FPGA-based PUFs have relatively low entropy and security. We propose a new design process that will produce new PUF architectures with higher entropy and security.
