Employing a blockchain platform for authenticating devices makes the process independent of the device manufacturer. This paper shows how cryptographic keys derived from a device's physical fingerprint can be employed in a zero-knowledge protocol to authenticate a device. As the keys are regenerated ...
In this work, we propose a blockchain-based AC system with zero-knowledge rollups to address the aforementioned issues. Our proposed system implements zero-knowledge rollups (ZK-rollups) of access control, where different AC authorization requests can be grouped into the same batch to generate a ...
zk-SNARKsis used in blockchain and cryptography applications to provide zero-knowledge proofs — these are fairly easy to create and then are quick to check. We can use them to prove that Bob has enough cryptocurrency to pay Alice, without revealing any of the details of his transactions...

We propose a blockchain-based continuous data integrity checking protocol with zero-knowledge privacy protection and formalize the system and security models for the proposal. 2. We provide a detailed construction for the abovementioned new protocol. In view of the time delay of the evaluation ...
The zero-knowledge proofs utilized in ZK-Rollups ensure that sensitive transaction details remain private while still being verifiable by the blockchain network. This enhanced privacy protection is particularly beneficial for applications dealing with sensitive financial or personal data, as it helps mitiga...
Besides, the use of smart contracts solves the problem of low computing efficiency of IoT devices and the waste of blockchain computing power resources. Finally, a proto- type of IoT access control system based on blockchain and zero-knowledge proof tech- nology is implemented. The test ...
