RF-PUF: Enhancing IoT Security through Authentication of Wireless Nodes using In-situ Machine Learning

3 May 2018Baibhab ChatterjeeDebayan DasShovan MaityShreyas Sen

Traditional authentication in radio-frequency (RF) systems enable secure data communication within a network through techniques such as digital signatures and hash-based message authentication codes (HMAC), which suffer from key recovery attacks. State-of-the-art IoT networks such as Nest also use Open Authentication (OAuth 2.0) protocols that are vulnerable to cross-site-recovery forgery (CSRF), which shows that these techniques may not prevent an adversary from copying or modeling the secret IDs or encryption keys using invasive, side channel, learning or software attacks...
