Abstract
AbstractWeb3.0 represents the ongoing evolution of blockchain technology, placing a strong emphasis on establishing a decentralized and user-controlled Internet. Current data delegation solutions for Web3.0 predominantly rely on attribute-based encryption algorithms (ABE) but lack the essential capabilities for processing ciphertext. Additionally, the attribute-based ciphertext transformation algorithm (ABCT) falls short when it comes to verifying the transformed ciphertext provided by data proxies. The primary objective of this article is to design a fine-grained and supervised attribute-based data delegating solution tailored specifically for Web3.0. This scheme aims to enhance the ciphertext processing capabilities of existing data delegation solutions based on blockchain and ABE. Additionally, it addresses the current limitations of ABCT technology. This includes its inability to verify re-encrypted ciphertext and ensure non-repudiation of transformation results. We leverage smart contracts to ensure the automatic execution of the data delegation process and to store permanent records on the blockchain for auditing and traceability. This approach guarantees a fair distribution of interests among all stakeholders. Furthermore, we employ a commitment mechanism and digital signature to enhance the regulatory compliance of existing ABCT technology. We present a secure access control and supervised data delegation scheme for Web3.0 with blockchain along with its instantiation, emphasizing its fine-grained nature and verifiability. Finally, the evaluation results demonstrate its practicality and effectiveness.
