Encryption method, decryption method, communication method, system and device

Abstract

The invention provides an encryption method, a decryption method, a communication method and systems and devices thereof. The method comprises the following steps: initializing a state vector K; performing binary conversion on the algorithm key to form a first byte stream, and generating an index number; marking frame header information of the algorithm key according to the index number; rotating the first byte stream to form a new password state vector Q; performing loss XOR calculation on the state vector K, the password state vector Q and the original character string to form a second byte stream; storing the second byte stream in an array to form a character encryption string; and according to the real-time timestamp, the index number and the data key, encrypting the character encryption string by using base64 to obtain an encrypted character string. According to the encryption and decryption method, on the basis of matrix loss symmetric conversion, the formed result is complex, cutting irregularity can follow, meanwhile, the generated string is the binary password stream, the generated string cannot be simulated, brute force cracking is difficult, and the safety level is high.

AI Technical Summary

Problems solved by technology

[0002] Common algorithms used for network communication encryption, such as RSA, are mostly used in network security checks in cloud systems. The process is complex, asymmetric encryption, encryption and decryption are slow, and the use of algorithms and the loading of algorithm libraries are also more troublesome. Without real-time verification of data communication, it is not suitable for real-time and fast interaction of LAN data
