Key Generation for Internet of Things: A Contemporary Survey
It addresses the problem of secure communication bootstrapping for IoT devices, but it is incremental as a survey paper.
This survey reviews and categorizes recent key generation protocols and systems for Internet of Things (IoT) devices, providing quantitative and qualitative comparisons, discussing security vulnerabilities, and outlining future research directions.
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.
