Abstract
This paper proposes a novel data security sharing system that integrates attribute-based encryption, keyword fuzzy search, and blockchain technology to address the poor performance and data vulnerability in existing data openness and sharing systems. The proposed system employs the attribute-based encryption algorithm to encrypt data, supplemented by blockchain technology to facilitate system search, thereby establishing the keyword search mechanism and repository for fragile items. The research results demonstrated that the average delay time for data sharing search in the new system ranged from 1.0 to 4.0 seconds, with a reduction of approximately 1100 milliseconds in encryption time compared with other methods. The average initialization time was between 15 and 20 milliseconds. Moreover, at an equivalent transaction volume, the proposed method exhibited a maximum processing time of 11.2 seconds, which was significantly improved by 4.2 seconds compared with other methods. These results underscore the enhanced performance of the proposed method in terms of encryption and keyword search efficiency, indicating its potential to advance data security sharing research and open up a promising path for future investigations.
