An Reliable Blockchain-Based Attribute Inner Product Encryption Data Sharing Scheme
Huazhi Wang, Bo Zhou · 2024
Data plays a critical role in modern digital economy and technological development.It has become one of the key elements driving economic growth.By analyzing massive amounts of data, businesses and governments can make more informed decisions, thereby improving productivity, optimizing resource allocation, and creating new economic value.Blockchain technology enables data sharing between different organizations or systems while maintaining data integrity and security, enhancing the efficiency of data flow across systems and industries.However, issues such as data privacy breaches, unclear access permissions, and poor usability of encrypted data still exist during data sharing.To enhance trusted data circulation, we propose a blockchain-based attribute inner product encryption data sharing scheme (BAIPE-DS), combining blockchain, attribute-based encryption, and inner product encryption technologies.This scheme addresses the problem of reliable data sharing in decentralized environments, achieves access control across departments, and provides encrypted data statistical analysis functions.Finally, we built a prototype system based on Python Charm to implement our proposed scheme and compared the time consumption of algorithms at various stages, verifying the feasibility and practicality of the scheme.
