On the (re)design of an FPGA-based PUF
Physically Unclonable Functions (PUFs) represent a promising basis for solutions to problems such as secure key storage, and delivery of higher-level applications such as authentication. Although effective PUF designs exist for CMOS-based technologies (e.g., arbiter PUFs), their implementation on FPGAs remains a challenge (e.g., because of their routing characteristics). With this in mind, Ande...
متن کاملA Comparative Analysis of Delay Based PUF Implementations on FPGA
Physical Unclonable Functions promise cheap, efficient, and secure identification and authentication of devices. In FPGA devices, PUFs may be instantiated directly from FPGA fabric components in order to exploit the propagation delay differences of signals caused by manufacturing process variations. Multiple delay based PUF architectures have been proposed. However, we have observed inconsisten...

متن کاملPUFKY: A Fully Functional PUF-Based Cryptographic Key Generator
We present PUFKY: a practical and modular design for a cryptographic key generator based on a Physically Unclonable Function (PUF). A fully functional reference implementation is developed and successfully evaluated on a substantial set of FPGA devices. It uses a highly optimized ring oscillator PUF (ROPUF) design, producing responses with up to 99% entropy. A very high key reliability is guara...
متن کاملPhysical Unclonable Function (PUF) Based Random Number Generator
Physical Unclonable Functions (PUFs) are widely used to generate random Numbers. In this paper we propose a new architecture in which an Arbiter Based PUF has been employed as a nonlinear function in Nonlinear Feedback Shift Register (NFSR) to generate true random numbers. The rate of producing the output bit streams is 10 million bits per second. The proposed RNG is able to pass all NIST tests...
