Abstract

The embodiment of the present invention discloses a smart contract authority verification method and device. The method includes: obtaining transaction request information sent by the client, the transaction request information includes the user certificate of the user, the MSP ID of the institution to which the user belongs, and transaction information. The MSP ID of the affiliated institution determines the institutional root certificate and institutional authority list of the institution to which the user belongs from the smart contract of the blockchain system. The list verifies the authority of the user, and executes the transaction information after the verification is passed. The present invention verifies the authority of the user according to the organization root certificate of the organization to which the user belongs and the authority list of the organization. In the contract, only the information such as the root certificate of the organization needs to be saved, and the respective user certificates are saved in the client, which can avoid the management of a large number of public and private key pair, which optimizes the transaction request information verification process.

Description

technical field [0001] The present invention relates to the field of smart contracts, in particular to a method and device for verifying authority of smart contracts. Background technique [0002] At present, the authority verification method of smart contracts mainly controls the "fine-grained" authority of each participant from the application layer, so that the interests of each participant in the business can be guaranteed. The method adopted is that when the smart contract is deployed, a one-to-many mapping relationship can be established between various permissions in the smart contract and the public keys of each participant; when an organization invokes one or more permissions in the smart contract, Transactions need to be signed. The contract extracts all public keys with callable permissions from the mapping table, and uses these public key signatures for verification. Only after the verification passes and has the relevant permissions can it be called. [0003] ...
