IoT, Volume 7, Issue 1

2026 March - 29 articles

Cover Story: This work presents an automated framework designed to evaluate the statistical quality of random number generators used in Internet of Things (IoT) security applications. The platform integrates the NIST SP 800-22 statistical test suite into a web-based environment that allows researchers and devices to execute randomness tests programmatically through REST interfaces. The system supports concurrent evaluations, automated analysis, and real-time reporting. Experimental validation using data generated by an ESP32-C3 hardware TRNG demonstrates that the framework can reliably detect weaknesses in pseudo-random generators, while confirming the statistical properties of true random sources. View this paper
