Physical unclonable functions (PUF) are hardware primitives that are very attractive for cryptographic applications to generate and store secure keys. Dynamic random access memory (DRAM) has recently become a promising technology for the construction of PUFs. In this work, multi-valued PUFs (MVPUFs) based on DRAM retention patterns are constructed and assessed for the first time. We propose a holistic solution by considering the complete PUF processing chain consisting of physical PUF source, PUF readout, digitization, channel coding, and the application of a hash function. In contrast to previous DRAM PUFs, a 4-ary symbol instead of a binary one is derived from each PUF cell. This results in an increase of entropy and thus in an improved error correction performance. Unlike previous PUFs based on DRAM retention patterns, we do not require any debiasing algorithms. To the best of our knowledge, this is the first proposal of a multi-valued PUF based on DRAM. Its properties are an average inter-response distance of ≈ 0.48, an average intra-response distance of ≈ 0.04 under stable environmental conditions, and an entropy of up to 0.99 bit.
