“…Tebelmann et al proposed to used the signal-to-noise ratio (SNR) to estimate the duration of the TERO oscillation and then estimate the number of oscillation before than the TERO oscillations stop [13]. It is an efficient method but Mureddu et al proven that the same results can be directly obtain by using a real-time spectral analyzer and moreover they proposed a full methodology to clone the TERO [14].

“…Moreover, for protection against side channel analysis it is more efficient to generate correlated noise on the side channel to be not remove by differential analysis as proposed in [19] for cypher implementation. To do it, a possible way could be to use the intrinsic locking of oscillating cells study in [14]. Finally, an efficient solution would be to not allow the user to access directly to the challenges.…”

The design of a secure, efficient, lightweight silicon physical unclonable function (PUF) is a serious challenge for the hardware security community. In this context, this paper presents a survey of physical attacks targeting ring-based PUFs because such PUFs are known as some of the more efficient. The paper discuss the threats and try to propose solution to design efficient and secure ring-based silicon PUFs.

“…Moreover, a problem of many RO-based TRNGs and PUFs is that active attacks that inject electromagnetic signals can synchronize temporarily the ROs, which is known as locking phenomenon. The consequence is a statistically manipulated output in TRNGs and a denial-of-service (DoS) in PUFs [19]- [20]. One major issue for PUFs is that efficient methods based on side-channel passive attacks have been reported to clone RO-PUFs and TERO-PUFs, breaking their security [20].…”

Physically Unclonable Functions (PUFs) and True Random Number Generators (TRNGs) are cryptographic primitives very well suited for secure IoT devices. This paper proposes a circuit, named multibit-RO-PUF-TRNG, which offers the advantages of unifying PUF and TRNG in the same design. It is based on counting the oscillations of pairs of ring oscillators (ROs), one of them acting as reference. Once the counter of the reference oscillator reaches a fixed value, the count value of the other RO is employed to provide the TRNG and the multibit PUF response. A mathematical model is presented that supports not only the circuit foundations but also a novel and simple calibration procedure that allows optimizing the selection of the design parameters. Experimental results are illustrated with large datasets from two families of FPGAs with different process nodes (90 nm and 28 nm). These results confirm that the proposed calibration provides TRNG and PUF responses with high quality. The raw TRNG bits do not need post-processing and the PUF bits (even 6 bits per RO) show very small aliasing. In the application context of obfuscating and reconstructing secrets generated by the TRNG, the multibit PUF response, together with the proposal of using error-correcting codes and RO selection adapted to each bit, provide savings of at least 79.38% of the ROs compared to using a unibit PUF without RO selection. The proposal has been implemented as an APB peripheral of a VexRiscv RV32I core to illustrate its use in a secure FPGA-based IoT device.
