We present a lightweight PUF-based authentication approach that is practical in settings where a server authenticates a device, and for use cases where the number of authentications is limited over a device's lifetime. Expand

We derive new considerably tighter bounds for PUF-induced distributions that suffer from, e.g., bias or spatial correlations. Expand

We present differential sequence coding that scales efficiently across larger block sizes without having the super-linear increase in decoding complexity of prior approaches without increasing the implementation size of the key generation module noticeably. Expand

We introduce wiretap coset coding to PUFs to mitigate the secrecy leakage through the helper data. Expand

We evaluate manufacturing variations to generate secure cryptographic keys for embedded systems without secure key storage. Expand

We present a new syndrome coding scheme, called Differential Sequence Coding (DSC), for the first error correction stage and a convolutional code with Viterbi decoder as second stage error correction for PUFs. Expand

Helper data compression is a new concept to increase the efficiency of popular syndrome coding schemes. Expand

We present a highly optimized Viterbi decoder, adapted to the constraints of PUFs on FPGAs. Expand

We present FPGA implementations of the popular lightweight hash functions KECCAK, PHOTON and SPONGENT, and gives a systematic analysis of size and throughput. Expand

We present Complementary Index-Based Syndrome coding (C-IBS), a new and flexible fuzzy embedder for Physical Unclonable Functions (PUFs). Expand
