Entropy as a Service: Unlocking Cryptography's Full Potential
Apostol T. Vassilev, Robert L. Staples
Securing the Internet of Things (IoT) requires strong cryptography, which depends on the availability of good entropy for generating unpredictable keys and accurate clocks. Attacks abusing weak keys or old inputs portend challenges for IoT. EaaS is a novel architecture providing entropy and timestamps from a decentralized root of trust, scaling gracefully across diverse geopolitical locales and remaining trustworthy unless much of the collective is compromised.
