Embodiment Construction

[0028] Such as figure 1 Shown, this embodiment is by following technical scheme: the first step establishes the network center of information exchange and sets up the message data information database; The second step converts the Chinese character message into binary message encoding file by the message data information database; The third step is to encrypt the binary message encoding file with the backpack public key to generate a binary ciphertext file; the fourth step is to transform the binary ciphertext string into groups, disrupt the digital structure of the original byte, and reorganize the byte digits Combine to generate a pseudo-message file; the fifth step converts the file into a binary ciphertext file after receiving the pseudo-message file; the sixth step decrypts the binary ciphertext file through the backpack private key to generate a binary message encoding file; the seventh step The binary message encoding file is generated into a Chinese character message t...

Abstract

The invention relates to a compression method for Chinese character message data based on knapsack encryption. The compression method adopts the following technical schemes that step1, a network center for information exchange and a message data information base are built; step2, a Chinese character message is converted into a binary system message coded file through the message data information base; step3, the binary system message coded file is encrypted to generate a binary system cryptograph file through a knapsack public key; step4, a binary system cryptograph cluster is subjected to the conversion treatment of regrouping, a numerical digit structure of original bytes is disorganized, and byte numerical digits are recombined to generate a pseudo message file; step5, after being received, the pseudo message file is converted into a binary system cryptograph file; step6, the binary system cryptograph file is decrypted to generate a binary system message coded file through a knapsack private key; step7, the binary system message coded file generates a Chinese character message through the message data information base. The compression method for the Chinese character message data can save resource spending for transmission and resolving, and is easy to achieve.

Description

Technical field: [0001] The invention relates to a method for compressing Chinese character message data based on knapsack encryption. Background technique: [0002] With the rapid development of communication technology and computer technology and the further development of Internet applications, digital communication has almost replaced all forms of analog communication, and the amount of data that needs to be transmitted, processed, and stored is increasing day by day, which has caused an increasing impact on transmission bandwidth, storage capacity, and processing speed. of great pressure. Trying to solve the problem by expanding the transmission bandwidth and increasing the storage capacity is not only expensive and unaffordable, but also requires increasing confidentiality of the transmitted messages. Therefore the best solution is to try to reduce the required bandwidth of data transmission through compression algorithm and encryption method, and realize information ...
