Secure identity authentication scheme based on PUF for IoUT
<p>Jie Zhou</p> · Academic Journal of Computing & Information Science · 2021
The existing identity authentication schemes based on the devices of Internet of Underwater Things (IouT) are all executed at the network layer and higher layers, which require high computing costs and are not suitable for devices with limited computing resources. By applying PUF to key binding, a physical layer-based identity authentication scheme is proposed. The authentication process is realized by the joint typicality coding and decoding technology based on the packing lemma and the covering lemma. The Achievability and Converse propositions prove the feasibility of the scheme, and the confidential capacity domain is delimited from the perspective of information theory. The false authentication analysis theoretically limits the probability of successful deception by the adversary, and reduces it to the lowest limit.
