A scalable and secure attribute-based access control method in Internet of Things with efficient revocation

Abstract

The Internet of Things (IoT) is an emerging network paradigm that understands the Because IoT is connections between all things and is the foundation of the intelligent community. The pervasive, always about everyday life or daily work of the user, privacy and security are important. In other complex and heterogeneous properties of the IoT make its security issues very challenging. words, how to achieve data, while data privacy is a challenging task. In addition, resource constraints In spite of the attribute based of node creates a lightweight requirement for IoT security mechanisms. encryption like (CP-ABE), can provide access control to data by allowing specific users who their This paper provides a method of a attributes in accordance with the policy of access to decoded text. scalable and secure access control based on attribute with effective revocation based on allow users to access and as well as the possibility of expiring some users' access. Security and efficiency evaluations show that the proposed scheme can achieve the desired security goals, while keeping comparable computation overhead.
