Embodiment Construction

[0024]Seefigure 1 , A traceable encrypted data transmission method and system, the data transfer steps are as follows:

[0025]Step 1: Transform the string into the byte row, specify different code via encoding, convert the string into different code pages corresponding to the code, and behave in the form of byte [];

[0026]Step 2: Encrypt by the public key to encrypt the byte fluid, including first encryption, secondary encryption, and three encryption;

[0027]Step 3: After the encryption is completed, form a ciphertext, transmitted through network, and seal;

[0028]Step 4: Decryption by the public key to the byte fluid, including first decryption, second decryption and three decryption;

[0029]Step 5: After the decryption is completed, obtain the byte streak, and then convert to a string clear text, complete the transmission.

[0030]Seefigure 2 The data transmission is performed by the operating terminal, and the operating terminal can be a desktop computer, a notebook, a tablet or a mobile ph...

Abstract

The invention discloses a traceable encrypted data transmission method and system, and the method comprises the following data transmission steps: 1, converting a character string plaintext into a byte stream plaintext, assigning different codes through Encoding, converting the character string into codes corresponding to different code pages, and representing the codes in a byte [] form; 2, encrypting a byte stream plaintext through a public key, wherein the encryption comprises first encryption, second encryption and third encryption; 3, after encryption is completed, forming a ciphertext, and obtaining sealing through network transmission; 4, decrypting the byte stream plaintext through the public key, wherein the decryption comprises first decryption, second decryption and third decryption; and 5, after decryption is finished, obtaining a byte stream plaintext, and converting the byte stream plaintext into a character string plaintext to finish transmission. According to the method, three times of encryption are carried out during file transmission, so that the security of ciphertext during transmission can be improved, and meanwhile, when the file is operated, the operation security of the file is ensured through multiple types of identity verification.

Description

Technical field[0001]The present invention belongs to the field of encrypted data transmission, specifically a traceable encrypted data transmission method and system.Background technique[0002]Data transmission refers to the process of transmitting data between a data source and data, which is transmitted between a data source and data, and a process of transmitting data from a signal source and a signal. operating.[0003]With the development of globalization, some larger companies will open the branch overseas. When allocating tasks and annual plans, they will distribute various confidential documents to the branch office through the form of the Internet.[0004]Since there is a vicious competition between the merchants, the commercial confidentiality of competitors will be transmitted, so some confidential documents will be transmitted, and the current encrypted transmission is only used by single-layer encryption. The encryption safety factor is not high, and at the same time, in en...
