Modular evaluation platform for evaluation and testing of physically unclonable functions

Abstract

Physical unclonable functions in field programmable arrays are always linked to the used hardware. Therefore, it is necessary to have high amount of simple devices for evaluation purposes. One of the suitable platform for such evaluation is HECTOR Evaluation Platform. The following paper describes this platform, compares it with existing solutions, and shows several examples of its using. The proposed platform consists of a motherboard and exchangeable daughter board modules. These are designed to be as simple as possible to allow cheap and independent evaluation across many devices. In comparison to similar existing solutions, proposed platform excels in its simple architecture, which allows remote using of module. The platform is also suitable for evaluation of other cryptographic primitives like true random number generators, encryption systems, and etc. Platform's components are adjusted for side channel attacks measurements. HECTOR evaluation platform was designed and optimized to fulfil the European HECTOR project (H2020) requirements.

Entropy Computation for Oscillator-based Physical Random Number Generators

“…Next, we evaluated the relevance of our entropy estimation and entropy management methods for MO-TRNGs based on ring oscillators, which were implemented in hardware. We used a modular hardware dedicated to TRNG and PUF testing, which featured the Intel 5CEBA4F17C8N device from the Cyclone V FPGA family [16]. We imple-mented three versions of the MO-TRNG following the circuit diagram depicted in Fig.…”
