Abstract

This invention relates to a method for transmitting data safely including: 1, a transmission end codes the original data necessary to be encrypted uniformly, 2, the transmission end ciphers the contained code data then transmits them, 3, the receiving end de-ciphers the received data then decodes said code data in terms of step 1 to get the encrypted original data, which are coded as follows: converting the necessary ciphered original data to ASCII code, then converts every character in the ASCII code to a corresponding hexadecimal system to form an emphasized ciphered data block of fixed format, or first of all converts the necessary emphasized encrypted data to the hexadecimal to form the data block with fixed format.

Description

technical field

[0001] The invention relates to the security field, in particular to a method for secure data transmission. Background technique

[0002] Network security solutions can be divided into two categories: one is a passive defense solution represented by firewall technology, and the other is an active open solution with data encryption and user authorization authentication as its core. Passive security solutions can only passively protect the security of the enterprise intranet, and have special requirements for the topology of the network. The active and open solution based on data encryption and user authentication does not require any network structure, and can directly actively protect the source data to achieve end-to-end security. In an active open solution, only designated users or network devices can interpret encrypted data. There is no doubt that encryption technology is the core of this type of solution. Encryption technology is a technology for encod...
