Abstract

The invention discloses a blockchain access control method, a blockchain access control device and a computer readable storage medium. The blockchain system provided by the invention completes the identity authentication of a member of a role corresponding institution by a group signature algorithm, and implements the access of encryption data by using a digital envelope technology; through the concept of groups and roles, each group corresponds to a role, and each role may correspond to multiple institutional members, so that the blockchain system supports the scenarios of multi-user data access. Compared to the traditional relational database-based data access system, the blockchain system in the application is strong in scalability, and capable of easily implementing inter-agency accesscontrol. And in this embodiment, the signature operation of the group signature algorithm and the verification time for verifying the group signature are independent of the number of group members, thereby improving the operation efficiency of the blockchain system during data access.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain access control method, device and computer-readable storage medium. Background technique [0002] The blockchain is a chain composed of a series of blocks. In addition to recording the data of this block, each block also records the Hash (hash) value of the previous block. In this way, a chain is formed. There are two core concepts of the blockchain, one is cryptography technology, and the other is the idea of ​​decentralization. Based on these two concepts, the historical information on the blockchain cannot be tampered with. A block consists of a block header and a block body, where the block header definition includes important fields such as the height of the block and the hash value of the previous block, while the block body mainly stores transaction data. The blockchain system is widely used to implement cryptocurrencies and build decentralized ...
