User-centric access control for efficient security in smart cities

Access control is a building block for the overall security of any communication system. In the Internet of Things (IoT), delegated authorization mechanisms are necessary to relieve constrained devices from the duty of identity management and access control tasks. Smart cities require new user-centric authorization approaches for IoT devices that preserve user privacy while guaranteeing scalability and efficiency. This paper introduces SMARTIE, an integrating platform for user-centric, secure IoT applications. SMARTIE efficiently provides decentralized access control for IoT devices based on user privacy preferences.
