Zusammenfassung:The article presents a plan for distributing access control and data sharing through CP-ABE. This plan allows for provable security and privacy protection without requiring authorization agencies. The main key of the CP-ABE algorithm is managed in a distributed manner based on blockchain through proxy key encapsulation technology, and a blockchain dual-chain model is adopted to improve system performance and security. At the same time, the block structure and data format specifications are designed to achieve on-chain supervision with traceable management and operational behavior of the PKEM-CPABE algorithm. Experimental simulation analysis shows that the proposed algorithm achieves an efficient and secure sharing mechanism while protecting data privacy.
