A Computationally Intelligent Hierarchical Authentication and Key Establishment Framework for Internet of Things
This addresses security challenges for IoT systems in sensitive sectors like health or finance, but it appears incremental as it builds on existing hierarchical approaches.
The paper tackles the authentication problem in IoT by proposing a hierarchical security architecture with computationally lightweight protocols that intelligently distribute computational load across multiple levels, pushing it towards upper layers, though no concrete performance numbers are provided.
Our high expectations from Internet of Things (IoT) and how it will positively influence our lifestyles depend on a secure and trusted implementation of it, especially in the sensitive sectors such as health or financial. IoT platforms and solutions must provide Confidentiality, Integrity and Availability (CIA) in a secure and transparent way. Due to the extremely large scales of IoT, traditional centralized solutions for security provisioning cannot be employed in their original form. This article discusses the authentication problem in IoT, which is fundamental to providing CIA. We propose a hierarchical security architecture for this problem and focus on computationally lightweight authentication protocols which can intelligently distribute the computational load across multiple levels and effectively push the load towards upper layers.
