Problems solved by technology

However, all information is transmitted in clear text, so some private information, such as e-mail, is often easily intercepted or tampered with during transmission, and confidential information e-mails are very easy to be illegally forwarded to non-related persons

Embodiment 1

[0021] The sending end of computer information is A (encryption key is Kea, decryption key is Kda), the receiving end of computer information is B (encryption key is Keb, decryption key is Kdb),

[0022] Step 101: the intelligent DES key generating device of computer information sender A generates DES key K;

[0023] Step 102: the intelligent RSA key pair generating device of the computer information receiver B generates an RSA key pair;

[0024] Step 103: the intelligent DES key encryption device encrypts the DES key K generated by the intelligent DES key generation device to generate the DES encrypted key Kea; the intelligent RSA key decryption device generates an RSA key to the intelligent RSA key pair generation device Encrypt to generate RSA's public encryption key Keb;

[0025] Step 104: The intelligent information receiving and transmitting device of computer information sending end A acquires the key Keb publicly encrypted by the intelligent RSA key decryption device,...

Abstract

The invention relates to a computer information transmission intelligent encryption method. According to the method, the encryption and decryption speed of files during transmission can be increased; transmitted encrypted messages carry RSA-encrypted DES (data encryption standard) keys, so that the risks of divulgence of the keys during the transmission can be reduced, and the threat of network monitoring on information security can be effectively avoided; meanwhile, by means of a signature and authentication function and an RSA algorithm, both communicating parties can send the personal signature information to each other for reservation and authentication; the keys are convenient to manage, every communicating object simply needs to secretly keep the personal RSA decryption key.

Description

technical field [0001] The invention relates to an intelligent encryption method for computer information transmission, which belongs to the technical field of computer information transmission. Background technique [0002] With the rapid development of computer technology, computers have become an indispensable tool in people's work, study and life. Computer networks also allow people to communicate anytime and anywhere, especially the information sharing that has emerged in recent years. It can be sent to any place you specify in the world in a very fast manner within a few seconds, and it can communicate with any place in the world. A corner of the network user contacts, the information can be text, image , sound and other ways, at the same time, users can get a lot of free news, special emails, and realize easy information search. However, all information is transmitted in clear text, so some private information, such as e-mail, is often easily intercepted or tampered...
