Abstract

The invention relates to a block chain data transmission method and a block chain data transmission system, and the method comprises the steps: carrying out the Hash operation of at least two times ontransaction data, and obtaining first abstract information; encrypting the first abstract information for multiple times by using at least two private keys to obtain digital signature information ofthe transaction data; and sending the transaction data, the digital signature information of the transaction data and at least two public keys corresponding to the at least two private keys to the block chain network node. According to the scheme of the invention, at least two Hash algorithms are adopted; the Hash internal operation complexity and the Hash output length are improved; any input change can generate different outputs. Compared with the prior art, the digital wallet has the advantages that attack resistance is improved, high efficiency is achieved on the premise that conflict resistance is not sacrificed, at least two private keys are utilized for multiple times of encryption, in other words, the information credibility is improved through the multiple digital signature technology, information can be fully verified not to be forged, tampered in the transmission process is avoided, and the safety of the digital wallet is improved.

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...
