Securing the Internet of Things (IoT) in a Decentralized World
summary
Claims that replacing username/password logins with no-password authentication (public/private keys registered on a blockchain) prevents credential stuffing, that storing encryption keys and device ownership on a ledger improves integrity, and that smart contracts automate policies like timed data deletion. Demonstrations point to IP cameras as high-risk devices, cite market figures (industrial IoT > $860B, ~40 billion devices by 2033) and propose tooling: blockchain key management, lightweight ciphers (Simon, Speck, PRESENT), a pairing system to cut latency and MAR-based consensus fixes.
