摘要：
This paper proposes an adaptive Time-Bound Attribute-Based Encryption Scheme (TB-ABE). TB-ABE is a fine-grained data access control scheme that maintains a secure data exchange environment between IoT devices. The lifetime of the system is divided into equal periods of time slots with unique encryption keys. TB-ABE combines Cyphertext-Policy Attribute Based Encryption with Time-bound keys. It only permits data users with attributes that satisfy the access policy set by the data owner to access the data for a specific period. It also proposes an efficient indirect revocation handling mechanism with minimal computations. The proposed scheme is implemented in Fog-Cloud computing architecture, where fog devices are used for partial outsourcing of encryption and decryption operations. This paper provides security and performance analysis for the proposed scheme in terms of computation, storage, communication and energy overheads. Analysis of proposed scheme proves its feasibility for limited-resource devices, while maintaining a secure communication between IoT devices. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
