Data security of an information system and data delay encryption are two of the key issues in the digital age. One of the research directions is to integrate blockchain with attribute encryption algorithm, ensuring data security, privacy, reducing decryption complexity and improving the efficiency of decryption. This study makes use of the ABE algorithm of blockchain, combines the advantages of attribute encryption and blockchain technology, and takes the blockchain as the carrier to complete fine-grained scheme for data access control and efficient decryption. By associating the attributes used for data encryption and access permissions, and giving full play to distributed and immutable characteristics of blockchain, secure and reliable data sharing and access control can be realized. The experimental results show that the encryption/decryption time based on blockchain ABE algorithm is 7-15 seconds, and the traditional method needs 14-20 seconds. The ABE algorithm of blockchain has a very important application prospect in the data security of the information system and data delay encryption.
