An Evaluation Procedure for Comparing Clock Jitter Measurement Methods

Popis výsledku v původním jazyce

According to recent security standards, the source of randomness of a true random number generator (TRNG) needs to be monitored online as well as inside the device to guarantee unpredictability and hence security. Monitoring is accomplished by measuring the physical parameters of the generator that determine the entropy rate per bit of the output bit-stream. The same parameters are preferably used as inputs for the stochastic model. Large majority of TRNGs implemented in logic devices use the clock jitter as a source of randomness. Consequently, the jitter is one of the main parameters to be characterized and observed. Several jitter measurement methods have been proposed in the last decade, but their precision and design constraints have not yet been objectively compared. We propose a simple yet useful methodology for the precise evaluation of jitter measurement methods including their design constraints. Our evaluation procedure relies on an analytical model of the jitter measurement method and simulations based on the model followed by stringent analysis of measurement errors. The new evaluation procedure is illustrated on four jitter measurement methods. The results clearly reveal differences in precision and in feasibility in hardware between the methods and confirm the usefulness of the new approach. In particular, the method presented in [7] proved to be the best performing, with an average measurement error of less than 10 and 93 implementable on an FPGA at that level of precision. 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
