A Distributed Publisher-Driven Secure Data Sharing Scheme for Information-Centric IoT,In Information-Centric Internet of Things (ICIoT), Internet of Things (IoT) data can be cached throughout a network for close data copy retrievals. Such a distributed data caching environment, however, poses a challenge to flexible authorization in the network. To address this challenge, Ciphertext-Policy Attribute-Based Encryption (CP-ABE) has been identified as a promising approach. However, in the existing CP-ABE scheme, publishers need to retrieve attributes from a centralized server for encrypting data, which leads to high communication overhead.we gift CCN(content material-centric networking) which treats content material as a primitive – decoupling area from identity, to the net at an unprecedented rate figuring out the concept of the net of things (IoT).
