Encryption and decryption method in a block chain technology

Abstract

The invention provides an encryption and decryption method in the blockchain technology. The encryption method is to first re-encode the original information by means of a combination of encoding elements to form an information source; and then obtain the code value of each element of the information source. Encrypt the information source after any combination of modulo, addition, subtraction, multiplication, division, XOR, OR, AND, NOT operation; set the first receiving ID at the receiving end to receive the ciphertext of the added unique ID; Finally, the length of the encrypted ciphertext received by the first receiving ID is counted, and then the encrypted ciphertext is re-encoded by means of a combination of coding elements to realize the encryption of the original information. The decryption method is to first judge the legitimacy of the ciphertext; decode the ciphertext judged to be legal to generate the information source of the ciphertext; decrypt the information source of the ciphertext, and generate the information source containing redundant information and a unique ID ; Finally, judge the legitimacy of information sources with redundant information. The present invention can effectively prevent illegal decryption to improve security.

Description

technical field [0001] The present invention relates to the field of encryption technology, and more specifically, to an encryption and decryption method in blockchain technology. Background technique [0002] At present, the capital flow of mobile payment mainly occurs on the Internet platform, and the level of risk management and control of related activities depends entirely on the Internet platform. Therefore, there is a blind spot in the supervision of capital flow in this method, which can easily lead to large-scale systemic financial risks. These are all industry-wide systemic risks brought about by systemic problems in network communication. Because data and identities can be intercepted, imitated, and read during the transfer process, network information systems transmit data through wired or wireless means, which provides the possibility of illegally obtaining data and illegally simulating user behavior through the Internet. [0003] In the existing technology, ma...

Problems solved by technology

[0003] In the existing technology, machine vision can directly peek at passwords, and machine learning can quickly compare the mapping relationship between plaintext and ciphertext. Therefore, in the face of artificial intelligence and machine learning technology, the use of traditional encryption and decryption technology basically cannot provide security protection
