The embodiment of the invention relates to a data processing method and apparatus based on blockchains. The apparatus comprises a plurality of private blockchains, the plurality of private blockchainscomprise a main chain, and the others are auxiliary links, each auxiliary link comprises multiple pairs of keys, each pair of keys has an identifier, each identifier can uniquely identify a key pair,and each auxiliary link is encrypted by a public key of the main chain. The method comprises the following steps: determining first specified information; assigning a first target key pair to the first specified information, and recording the identifier of the first target key in the main chain; decrypting the auxiliary link corresponding to the identifier of the first target key by using a private key of the main chain, and obtaining a first target public key or a first target private key corresponding to the identifier of the first target key; and encrypting the first specified informationby using the first target public key, or signing the first specified information by using the first target private key. The difficulty of hacking, information leakage, brute force and the like is increased.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain-based data processing method and device. Background technique [0002] With the rapid development of the Internet, people quickly ushered in the information age. In the information age, data has value. However, due to the high openness of the Internet, people are facing more and more threats such as hacker attacks, information leakage, and violent cracking when transmitting information, which has caused great security risks to their own interests, commercial secrets, and even national security. . [0003] Encrypting data can effectively reduce the above threats and improve security. [0004] Encryption technology consists of two elements: algorithm and key. Algorithm is the step of combining ordinary information or understandable information with a string of numbers (key) to generate incomprehensible ciphertext. Key is an algorithm used to encode and d...
