Description

A multi-channel encrypted information transmission method

technical field

A multi-channel encrypted information transmission method belongs to the field of communication technology and relates to an encrypted information transmission method.

Background technique

With the development of communication technology, the use of GPRS, EDGE, CDMA, 802.11, ADSL and other networking methods for Internet data communication has a wide application base, but using the Internet to transmit encrypted data, security will become a very difficult problem. Especially for some special industries, if the data in the communication process is intercepted, it will cause great losses.

In most applications, people hope that the relevant information can be safely and confidentially transmitted to the recipient during the information exchange process, and they do not want the information to be threatened by interception during the transmission process, or even completely intercepted, resulting in losses. However, since the use of wireless channels or Internet networks cannot be avoided during the transmission of information, theoretically all information may be intercepted during transmission. A possible solution to secure communication is to establish various dedicated communication networks or communication lines. However, the biggest disadvantage of this is that the investment cost is too high, and it is impossible to solve the information exchange between different dedicated networks. Another method is to realize confidential communication through information encryption on the basis of existing communication technology and network. Because in theory, using the public network or public wireless channels to transmit encrypted information, although the information may be intercepted, but because the person who intercepts the information intercepts the encrypted information, if he cannot decrypt it, he cannot Really get information content. Therefore, various information encryption technologies have developed unprecedentedly, and encrypted information communication methods based on a single wireless channel or Internet transmission have gradually been applied.

However, the so-called "the Tao is one foot high, the devil is one foot high". At present, no one in the world has been able to invent an information encryption technology that absolutely cannot decrypt encrypted information without knowing the encryption method in advance. In theory, any encryption technology has the possibility of being deciphered, it's just the length of time. Therefore, people hope to find a way to further improve the security of encrypted information during the transmission process on the basis of information encryption: that is, to further reduce the possibility of being intercepted, even in the case of being intercepted. Can further reduce the possibility of information being deciphered

The invention solves the problem of data security by utilizing the transmission encryption technology realized by multiple channels.
