Foundations of Reconfigurable PUFs
A Physically Unclonable Function (PUF) can be seen as a source of randomness that can be challenged with a stimulus and responds in a way that is to some extent unpredictable. PUFs can be used to provide efficient solutions for common cryptographic primitives such as identification/authentication schemes, key storage, and hardware-entangled cryptography. Moreover, Brzuska et al. have recently s...
متن کاملOn the Security of PUF Protocols under Bad PUFs and PUFs-inside-PUFs Attacks
We continue investigations on the use of so-called Strong PUFs as a cryptographic primitive in realistic attack models, in particular in the “Bad/Malicious PUF Model”. We obtain the following results: – Bad PUFs and Simplification: As a minor contribution, we simplify a recent OT-protocol for malicious PUFs by Dachman-Soled et al. [4] from CRYPTO 2014. We can achieve the same security propertie...
متن کاملIntrinsic PUFs from Flip-flops on Reconfigurable Devices
Intrinsic Physical Unclonable Functions or PUFs have been introduced as a highly secure method to extract digital identifiers and keys from integrated circuits. In the setting of reconfigurable devices, like FPGAs, they can be used to protect the IP contained in the design in a cost-effective and tamper-evident way. In this work, a new type of PUF construction for reconfigurable devices is intr...
متن کاملOptical PUFs Reloaded
We revisit optical physical unclonable functions (PUFs), which were proposed by Pappu et al. in their seminal first publication on PUFs [40, 41]. The first part of the paper treats non-integrated optical PUFs. Their security against modeling attacks is analyzed, and we discuss new image transformations that maximize the PUF’s output entropy while possessing similar error correction capacities a...
متن کاملPLayPUF: Programmable Logically Erasable PUFs for Forward and Backward Secure Key Management
A silicon Physical Unclonable Function (PUF) is a hardware security primitive which imple-ments a unique and unclonable function on a chip which, given a challenge as input, computes aresponse by measuring and leveraging (semiconductor process) manufacturing variations whichdi er from PUF to PUF. In this paper, we observe that by equipping a PUF with a small,constant-sized, tamp...
