ABSTRACT
With the rapid development of online education, the security sharing of digital education resources has become a hot topic. Blockchain technology is difficult to be tampered with, decentralized and other characteristics, suitable for protecting the copyright of digital education resources, but the on-chain data is transparent and open, there are hidden dangers of on-chain data security. Secondly, blockchain has limited storage capacity and is not suitable for storing a large number of digital educational resources. The education resource access control model proposed in this paper combines distributed file system with blockchain, which stores the summary information of education resource data. Based on the one-to-many sharing scenario of digital education resources, Ciphertext-Policy Attribute Based Encryption is adopted to implements fine-grained access control. Based on the storage demand of massive education data, IPFS is used to distribute all kinds of digital education resource files to share the storage pressure of blockchain.
