Abstract

Sequences of high quality random bits are required in virtually all modern security and cryptography applications, pushing designers to devise hardware-based true random number generators (TRNGs). Alongside architectures made by big players of information technology and/or proposed via peer reviewed channels, many alternatives exist. The recent, powerful trend to interconnect even humble devices creates a significant deployment space for some of them, thanks to properties such as low-cost, good suitability to augment existing hardware, and readily available hardware/firmware/driver designs with liberal licenses. Consequently, there is practical relevance in a formal evaluation of their design. In this work, the "InfNoise" and "Redoubler" open architectures are investigated, finding them to belong to the chaos-based TRNG class and to bear similarity to some academic designs from the late'90s. Despite some some margins for improvement, the designs are found to admit formal justification.
