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

Abstract

The present invention provides an encryption method, a decryption method, a communication method and the system and device thereof, including: initializing the state vector K; performing binary conversion on the algorithm key to form the first byte stream, and generating an index number; The frame header information of the algorithm key is marked; the first byte stream is rotated to form a new password state vector Q; the state vector K, the password state vector Q and the original string are XOR calculated to form the second word Throttling; store the second byte stream in an array to form an encrypted character string; according to the real-time timestamp, index number and data key, use base64 to encrypt the encrypted character string to obtain an encrypted string. The encryption and decryption method in the present invention is based on the lossy symmetric conversion of the matrix, and the resulting result is complicated, and there are no rules to follow. At the same time, the generated string is a binary cipher stream that cannot be simulated, is difficult to be cracked by violence, and has a high security level.

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
