Decentralized Lightweight Group Key Management for Dynamic Access Control in IoT Environments
Rapid growth of Internet of Things (IoT) devices dealing with sensitive data has led to the emergence of new access control technologies in order to maintain this data safe from unauthorized use. In particular, a dynamic IoT environment, characterized by a high signaling overhead caused by subscribers' mobility, presents a significant concern to ensure secure data distribution to legitimate subscribers. Hence, for such dynamic environments, group key management (GKM) represents the fundamental mechanism for managing the dissemination of keys for access control and secure data distribution. However, existing access control schemes based on GKM and dedicated to IoT are mainly based on ce…
Authentication and authorization security solution for the internet of thing
The Internet of Things (IoT) represents the interconnection between the Internet and physical objects, places and environments. However, this extensive connectivity of IoT can be hampered by malicious interventions from cyber attackers. Thus, ensuring security for users and IoT devices remains a challenge, especially authentication and authorization, which are essential building blocks of the security process. This is due to the unconventional IoT characteristics, including scalability, heterogeneity, interoperability, and dynamic changes, which make the existing security measures inadequate. Indeed, these characteristics bring up several security requirements to consider when defining a se…
