“…UWB systems perform indoor localization and communication, in line with IEEE 802.15.4 [143][144][145][146]. Several works [147][148][149][150][151] have already performed investigations on PLS in UWB systems: [152] obtains a key generation rate of 18 bps and [41] shows that Eve correlation can reach 50%. However, to our knowledge, no investigation has been published so far regarding a time-frequency approach for UWB PLS key generation, such as the filterbank here presented.…”

The motivation for this study about Physical Layer Security comes from bridging the gap between the vast theory and a feasible implementation. We propose a Physical-Layer-Security Box as a system-level Box is a system-level solution, named PLS-Box, to solve the key exchange between two wireless communicating parties. The PLS-Box performs a novel key generation method named time-frequency filter-bank. The entropy of the radio channel is harvested via a filter-bank processing, and then turned into a reciprocal security key, at both ends. In this concept work, we also focus on several PLS open issues, such as radio-frequency imperfections and accessibility to the baseband communication modem. The goal is to show a wide applicability of our PLS-Box to actual wireless systems, paving the way for an evolution of existing schemes.

A New Frontier for IoT Security Emerging From Three Decades of Key Generation Relying on Wireless Channels

et al. 2020

The Internet of Things (IoT) is a transformative technology, which is revolutionizing our everyday life by connecting everyone and everything together. The massive number of devices are preferably connected wirelessly because of the easy installment and flexible deployment. However, the broadcast nature of the wireless medium makes the information accessible to everyone including malicious users, which should hence be protected by encryption. Unfortunately, the secure and efficient provision of cryptographic keys for low-cost IoT devices is challenging; weak keys have resulted in severe security breaches, as evidenced by numerous notorious cyberattacks. This paper provides a comprehensive survey of lightweight security solutions conceived for IoT, relying on key generation from wireless channels. We first introduce the key generation fundamentals and protocols. We then examine how to apply this emerging technique to secure IoT and demonstrate that key generation relying on the randomness of wireless channels is eminently suitable for IoT. This paper reviews the extensive research efforts in the areas of theoretical modelling, simulation based validation and experimental exploration. We finally discuss the hurdles and challenges that key generation is facing and suggest future work to make key generation a reliable and secure solution to safeguard the IoT.

“…Then, the EMG signal was rectified and converted into binary bits based on a shape-based key generation method. Finally, the same key was obtained by using Golay Code G (23,12) in the reconciliation to correct the mismatches. Evaluation results on 10 subjects suggested that EMG-KEY can reach a high bit rate of 5.51 bit/s with a success rate of 88.84%.…”

“…While RSSI is almost provided in all the wireless standards, CIR and CFR are only available in wideband systems. For example, UWB systems are able to estimate the CIR [12,133] while IEEE 802.11 Orthogonal Frequency-Division Multiplexing (OFDM) can obtain the CFR [72,135,154,159].…”

Key generation is a promising technique to bootstrap secure communications for the Internet of Things (IoT) devices that have no prior knowledge between each other. In the past few years, a variety of key generation protocols and systems have been proposed. In this survey, we review and categorise recent key generation systems based on a novel taxonomy. Then, we provide both quantitative and qualitative comparisons of existing approaches. We also discuss the security vulnerabilities of key generation schemes and possible countermeasures. Finally, we discuss the current challenges and point out several potential research directions. CCS Concepts: • Computer systems organization → Sensors and actuators; • Human-centered computing → Ubiquitous and mobile devices; • Security and privacy → Network security.
