Reconfigurable Security: Edge Computing-based Framework for IoT
This addresses security issues for IoT devices with resource constraints and compatibility problems, but it is incremental as it builds on existing edge computing concepts.
The paper tackles IoT security challenges by proposing a reconfigurable framework based on edge computing, which uses a security agent to simplify key management and offload computational costs, demonstrating feasibility and usability in performance analysis.
In various scenarios, achieving security between IoT devices is challenging since the devices may have different dedicated communication standards, resource constraints as well as various applications. In this article, we first provide requirements and existing solutions for IoT security. We then introduce a new reconfigurable security framework based on edge computing, which utilizes a near-user edge device, i.e., security agent, to simplify key management and offload the computational costs of security algorithms at IoT devices. This framework is designed to overcome the challenges including high computation costs, low flexibility in key management, and low compatibility in deploying new security algorithms in IoT, especially when adopting advanced cryptographic primitives. We also provide the design principles of the reconfigurable security framework, the exemplary security protocols for anonymous authentication and secure data access control, and the performance analysis in terms of feasibility and usability. The reconfigurable security framework paves a new way to strength IoT security by edge computing.
