Abstract

The invention relates to a blockchain encryption method and device, electronic equipment and a computer readable storage medium, relates to the technical field of blockchains, and can be applied to ascene of encrypting data in a blockchain. The blockchain encryption method comprises the steps of obtaining to-be-encrypted data sent by a first node in a blockchain; determining an encryption function; wherein the encryption function comprises a discrete encryption function and a continuous encryption function; determining a logic variable and a logic variable value of the logic variable; and performing alternate encryption processing on the to-be-encrypted data through the discrete encryption function and the continuous encryption function based on the logic variable value to generate encrypted data. According to the method and the device, the plaintext data in the block chain can be encrypted alternately by adopting Logistic mapping and sine chaotic mapping, so that the randomness of the chaotic sequence is further enhanced, the key space is expanded, and the data in the block chain is safer.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, and in particular, to a blockchain encryption method, a blockchain encryption device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of Internet technology and people's gradual attention to trust issues, how to ensure data security and confidentiality has attracted more and more attention. Blockchain technology, with its characteristics of anti-tampering and traceability, has become a key technology to solve this problem. [0003] At present, the application of cryptographic mechanisms such as symmetric algorithms, asymmetric algorithms, and hash functions in blockchains can solve problems such as message tamper resistance, privacy information protection, and digital asset security. However, attackers can still find loopholes in the blockchain system and carry out attacks. For example, attackers can still threaten the...
