Physical Layer Security 2.0: Emerging Wireless Security Solutions for Future IoT
ID: Tut-09
Description
The massive deployment of IoT makes information security unprecedentedly important. Physical layer security (PLS) is a wireless security solution which exploits intrinsic features of wireless channels to degrade the signal quality of eavesdroppers and realizes security via signal processing approaches. While extensive studies have been conducted in this area during the past decades leading to fruitful achievements, multiple fundamental problems have not been well addressed, which hinders practical adoption of PLS techniques in IoT-related applications. In this tutorial, we would like to introduce a new concept called PLS 2.0. Compared to the existing PLS research paradigm, referred to as PLS 1.0, the PLS 2.0 has three innovations. First, as opposed to existing PLS solutions which follow a heuristic design philosophy, a novel secure transmission architecture is developed, which combines PLS techniques and cryptographic primitives to achieve a provable security level. Second, a series of new PLS techniques will be presented in this tutorial. The mainstream PLS solutions, e.g., artificial noise and cooperative jamming, realize security at the cost of additional energy consumption or increased hardware complexity, which is not feasible for IoT. Different from this paradigm, we will introduce several lightweight PLS techniques including fountain-coding aided methods and the noise aggregation approaches. Finally, we will highlight the application perspective of PLS. While plenty of papers have been published in the PLS research field, most studies aimed at solving anti-eavesdropping problems. However, current cryptographic approaches are competent for accomplishing this, which makes PLS techniques less attractive to IoT. To bridge the gap between theory and practice, in this tutorial we would like to introduce three IoT-related scenarios where higher-layer encryption techniques do not work. The scenarios include: Fast device identification and authentication in IoT, secure ranging for contactless car entry, and privacy protection for wireless sensing. For each scenario, we will show how PLS techniques can be utilized to realize low-complexity authentication, integrity protection, and privacy enhancement.
