Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0031] A preferred embodiment is given below:

[0032] Such as figure 1 , 2 , 3, and 4, the file stream byte group data encryption and network transmission method in the present embodiment reads the file to be encrypted in the form of a file stream, and obtains the file stream byte array a of the file; to the array a and A round of XOR processing is performed on the iterative value of the logistic map to obtain a new byte array b of ...

Abstract

The invention relates to the field of file transmission, and particularly provides a file stream byte group data encryption and network transmission method. The file stream byte group data encryptionand network transmission method comprises the following steps: reading a file to be encrypted in a file stream manner to obtain a file stream byte array a of the file; performing a round of exclusiveOR processing on the array a and the logistic mapping iteration value to obtain a new file stream byte array b; scrambling the array b, sorting the sequences by using a logistic iterative sequence, and replacing the array b according to the logistic sequence to obtain a new byte array c; and performing BASE64 encoding on the finally obtained byte array to obtain a character string to be transmitted. Compared with the prior art, encryption is carried out from the byte stream level, so that the converted new coded bytes have higher information entropy and lower byte correlation degree and are used for resisting statistical attacks and inscription attacks, a guarantee is provided for network transmission security, and the method has good popularization value.

Description

technical field [0001] The invention relates to the field of file transmission, and specifically provides a file stream byte group data encryption and network transmission method. Background technique [0002] With the continuous expansion of the network ecological environment, network transmission vulnerabilities have begun to be exploited by people, who have begun to monitor the network and leak important information, resulting in frequent incidents that have caused heavy losses to individuals and businesses. Therefore, more and more attention is paid to the security of network transmission, and more and more attention is paid to the security of network file transmission. [0003] Many experts, scholars, and engineers have conducted in-depth research on the encryption of transmitted files, some have realized the encryption of personal file transmissions, some have improved the security of document transmission, and some have realized online editing of documents to enhance ...
