IIoT Data Sharing: CP-A$\!^{2}$2BE With Outsourced Decryption and Verifiable Revocation
- Published
- Record updated
Summary
This paper proposes CP-A$^{2}$2BE, a ciphertext-policy anonymous attribute-based encryption scheme for IIoT data sharing. It adds outsourced decryption through edge nodes deployed in factories, protects attribute privacy for devices and personnel, and introduces a commitment-based verifiable revocation mechanism. Experiments report a constant 26 milliseconds decryption time regardless of the number of attributes.
