Private blockchain-envisioned multi-authority CP-ABE-based user access control scheme in IIoT

Soumya Banerjee et al.

Summary: Recent advances in LPWAN are expected to enhance the proliferation of IIoT, but concerns about security and privacy challenges remain. This work proposes a novel blockchain-based user access control scheme for data security and scalability in IIoT. The scheme encrypts data using CP-ABE, supports multiple attribute authorities, and provides secure data access through blockchain implementation. Security analysis shows the scheme's robustness against attacks, and comparison with existing schemes highlights its advantages.

A Storage Optimization Scheme for Blockchain Transaction Databases

Jingyu Zhang et al.

Summary: Blockchain systems require nodes to copy a complete transaction database, leading to continuous database growth and the need to expand node memory. This paper proposes a storage optimization scheme based on the LRU algorithm, dividing transaction databases into cold and hot zones to optimize storage by moving unused transaction outputs out of memory. The proposed method outperforms current mechanisms for blockchain transaction databases, as supported by theoretical analyses and extensive experiments.
