Abstract

The invention discloses an authentication method and device based on a blockchain. The method comprises the following steps: generating a roll-out private key for transferring digital assets through the blockchain and a corresponding roll-out public key according to a random number; carrying out coding treatment on the roll-out public key, and generating a roll-in address; carrying out digital signature on the basis of the roll-out private key, a transferring numerical value of the digital assets to be transferred and the roll-in address; acquiring digital asset transferring data on the basis of the transferring numerical value, the roll-in address, the digital signature and the roll-out public key; and broadcasting the digital asset transferring data into the blockchain so that the digital asset transferring data are subjected to first-grade authentication by an authentication side, or are subjected to multi-grade authentication by a server side and the authentication side jointly after first-grade authentication is finished. Therefore, by the embodiment, hacker attack ability can be improved, and safety requirements of data and transaction in a blockchain open environment can be met.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a blockchain-based authentication method and device. Background technique [0002] Traditional digital asset interactions (such as electronic currency transactions) are usually completed by centralized institutions. Centralized institutions mainly involve third-party transaction payment platforms, bank account management systems, remote payment systems, transfer clearing systems, etc. Traditional digital asset interaction methods have problems such as cumbersome operations, opaque data, and easy tampering. [0003] With the development of communication technology, blockchain has gradually been applied to various data processing application scenarios due to its advantages of decentralization, openness, transparency, and inability to tamper. The blockchain can be regarded as a distributed unified ledger. All participants jointly determine the accounting content. Ea...
