TL;DR: This paper proposes an efficient mutual verifiable provable data possession scheme, which utilizes Diffie-Hellman shared key to construct the homomorphic authenticator and is very efficient compared with the previous PDP schemes, since the bilinear operation is not required.

TL;DR: The blockchain technology is utilized to build the first incentive mechanism of nodes as per data storage for wireless sensor networks (WSNs) and adopts the provable data possession to replace the proof of work in original bitcoins to carry out the mining and storage of new data blocks.

TL;DR: An identity-based proxy aggregate signature (IBPAS) scheme is proposed to improve the efficiency of signature verification, as well as compress the storage space and reduce the communication bandwidth.

TL;DR: This article uses the DCOMB method to build blockchain-based IoT data query model, which combines the data stream of the IoT with the timestamp of the blockchain, improving the interoperability of data and the versatility of the Internet of Things database system.

TL;DR: In this article, a blockchain-based identity management combining access control mechanism is designed under edge computing, where self-certified cryptography is utilized to realize the registration and authentication of network entities.
