Implement of agent with role-based hierarchy access control for secure grouping IoTs

摘要

Internet of Things (IoTs) is an enabler for the intelligence appended to many central features of the modern world, such as hospitals, cities, grids, organizations, and buildings. The security and privacy are some of the major issues that prevent the wide adoption of IoTs. Its storage and computing power of these devices is often limited and their designs currently focus on ensuring functionality and largely ignore other requirements, including security and privacy concerns. Role-based Access Control in a hierarchy is an interesting research topic in computer security. Many investigations have been published in the literature with solutions involving assigning cryptographic keys to users for secure scheme in IoTs environments. The new security requirements are required by secure grouping IoTs, which are required for new applications of grouping IoTs. However, the existing secure schemes require a large number of costly arithmetic operations with large integers. The traditional scheme is difficult to implement among the IoTs devices groups with lower computation ability. In this paper, we present a solution, an implement of agent with Role-based Hierarchy Access Control for secure grouping IoTs, suitable for role-based access control in IoTs groups. The proposed scheme has promising characteristics such as high computational efficiency, little required memory and low cost implementation in each IoT device organized to be an grouping IoTs with a secure hierarchy key management.
