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

Embodiment Construction

[0061] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0062] The invention provides a communication method, comprising the following steps:

[0063] For a raw string "HardwareType#1#1004",

[0064] Process 1 encrypts the original string to obtain the encrypted string 0YFhpus01y98UpMg1bAs0fICp9vHY7DEExd8p1XcQeE42Riuu6Iv.

[0065] Process one sends the encrypted string to process two.

[0066] After process 2 receives the encrypted string, it decrypts the encrypted string to obtain the original string HardwareType#1#1004.

[0067] Based on the same inventive concept, the present invention also provides a communication system, including an encryption module, a sending module, a receiving module and a decryption module.

[0068] Based on the same i...

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.

Description
