Abstract

The invention provides a data transmission method based on a block chain and a block chain node. The data transmission method based on the block chain is applied to a first block chain node, and specifically comprises the steps that the first block chain node encrypts target data by using a first encryption algorithm to obtain a first abstract corresponding to the target data; the first block chain node encrypts the target data and the first abstract by using a key of a second encryption algorithm to obtain a first ciphertext, and encrypts the key of the second encryption algorithm by using apublic key of a third encryption algorithm of a second block chain node to obtain a second ciphertext, wherein the key of the second encryption algorithm is randomly generated by the first block chainnode for the current round of data transmission; and the first block chain node sends the first ciphertext and the second ciphertext to the second block chain node. Therefore, the data transmission method with higher security is realized based on the block chain.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a blockchain-based data transmission method and blockchain nodes. Background technique [0002] With the continuous development and application of Internet technology, people rely more and more on the interaction of information through the Internet. Even important data or data that needs to be kept secret are transmitted through the Internet. Therefore, the security of data transmission between nodes is more and more important. [0003] Using an encryption algorithm to encrypt data before transmission is an effective method to improve the security of data transmission. One of the more secure data transmission methods mainly used today is data transmission based on blockchain technology. In blockchain technology, the basis of the ownership verification mechanism is an asymmetric encryption algorithm, so asymmetric encryption is mainly used for data transmissi...
