Abstract

The present invention relates to a blockchain data transmission method and a blockchain data transmission system, the method comprising: performing at least two hash operations on transaction data to obtain first summary information; The information is encrypted multiple times to obtain the digital signature information of the transaction data; the transaction data, the digital signature information of the transaction data, and at least two public keys corresponding to at least two private keys are sent to the blockchain network node. The scheme of the present invention improves the complexity of the internal operation of the hash and the length of the hash output through at least two hash algorithms, so that any input change can produce different outputs, and the ability to resist attacks is improved without sacrificing the ability to resist conflicts It is highly efficient under the premise that at least two private keys are used for multiple encryptions, that is, multiple digital signature technology increases the credibility of information, can fully verify that the information is not forged, and has not been tampered with during the transmission process, and improves the digital security. Wallet security.

Description

technical field [0001] The invention relates to the technical field of blockchain data secure transmission, in particular to a blockchain data transmission method and a blockchain data transmission system. Background technique [0002] With the popularization of Internet network transactions, digital signature technology is introduced in the transaction process. In the development of blockchain, digital signature technology is also introduced in order to prevent the sending node information and data from being maliciously forged and tampered with. [0003] Digital signature, also known as secret key digital signature, is a method of identifying digital information through secret key encryption. Based on this technology, the information sender can also prove the authenticity of the sent information by sending a string of digital characters that cannot be forged by others. [0004] Currently, the commonly used digital signature algorithm in the blockchain is ECDSA (Elliptic C...
