Communication system and communication method of chaos safety information internet transmission

Abstract

The invention discloses a communication system and a communication method for the Internet transmission of chaotic security information. An independent server, receiving and transmitting terminals and built-in bidirectional key transmission modules are mutually connected together to form the system. In the method, a transmitter encrypts image text information via chaotic security, which is then uploaded to the independent server, the encrypted key is independently sent to a receiver via a public telephone line channel, and the receiver downloads the chaotically encrypted image text information and utilizes the received encrypted key to decrypt the image text information. The image text information transmission between the receiving and transmitting terminals of the invention utilizes the point-to-multipoint communication method performed by Internet media, so the image text information transmission does not pass a third party normally using the Email transmission method, thus greatly enhancing the security and independence of information transmission on the Internet. The independent server applies multiple security measures aiming at the ftp protocol, thus enhancing the theft-proof capability of information. The transmission of chaotically encrypted keys in an independent telephone channel ensures the anti-attack capability of the image text information.

Description

technical field [0001] The invention relates to the technical field of internet chaotic information security transmission, in particular to a communication system and a communication method for internet transmission of chaotic security information. Background technique [0002] Using chaos technology to carry out point-to-point communication of two-way transmission of graphic information on the Internet, since the information transmission between each receiving / sending terminal is realized through the Internet public media system, in the transmission process according to the usual transmission protocol, Due to the publicity and openness of the third party that has passed through the media system, the security independence of information transmission is affected. For some applications that require strict security transmission, there will be certain information security risks. Therefore, establishing a point-to-multiple communication system based on an independent server-based...
