Abstract

In order to solve the problem of secure group communication on the public ledger of Hyperledger Fabric, based on the hierarchical structure of membership management in the Fabric channel, the paper proposed a public key broadcast encryption scheme for the consortium blockchain by combining the CS method under the subset-cover framework and the IBE algorithm. This scheme improved the complete binary tree structure of the CS method, and constructed a binary tree with hierarchical structure according to the organizational structure in the Fabric channel. This scheme adopted a Huffman-like coding method to uniquely identify the position of each node in the binary tree so as to improve the query speed. The scheme introduced the reserved node and the deprecated node, and designed the corresponding binary tree update algorithm to implement the dynamic joining and exiting of members. The analysis and experiment show that this scheme provides an efficient, secure and fine-grained data privacy protection scheme for the consortium blockchain.
