Abstract：Regarding the issue of low eficiency in traditional file-sharing scheme caused by cumbersome processes，a lightweight blockchain-based encrypted file secure sharing scheme is designed and implemented. This scheme adopts proxy re-encryption technique，using blockchain nodes to perform re-encryption operations in place of traditional proxy servers. In addition，the interplanetary file system （IPFS） peer to peer （P2P） network is employed to enable direct communication between data owners and users，significantly reducing system communication overhead. Experimental results show that the proposed scheme ensures user data security， while providing operational simplicity and end-user friendliness at the terminal，thereby effectively improving the efficiency of file sharing.
