FIELD OF THE INVENTION that present invention relate to the field of communications technology, A method for encrypt data transmission comprises the following steps: S1, a message body with the numberof bytes set as Ni2 is transmitted freely in Ni4 channels, a random number Ni1 is generated by using a timing counter, and the message body with the number of bytes set as Ni2 to be transmitted is randomly divided into Ni3 segment message body segmented data packets according to the random number Ni1; S2, the Ni3 segment message body segmented data packets separated in the previous step are randomly misordered by an encoder, and then are dynamically encrypted and transmitted in a random multi-channel manner; 3, message body is restored, wherein the receiving end receives the segmented data packets of each segment of the message body, stores and decrypts the true value of the restored data through a decoder, namely, reorganizing the segmented data of each segment of the message body into complete message body data according to a packet sequence number and a misordering rule, and sequentially splicing the segmented data of each segment of the message body. The invention solves the problem that the encryption mode of the existing intelligent security system is simple and easy to cracke and the intercepted information has the hidden danger of safety.

The invention discloses a secure communication method based on multichannel signal fragmentization transmission technology. The secure communication method comprises the following steps: dispersing communication data into small fragments in an information transmitting terminal, and then transmitting the small fragments by multiple information channels according to a certain rule; and receiving fragmentization data transmitted by the multiple channels in an information receiving terminal, and integrating the fragmentization data according to the fragmentization rule when the information is sent to obtain complete data transmitted by the transmitting terminal. The dispersion and integration rules of the fragments are determined by keys in the transmission process. By adoption of the secure communication method provided by the invention, on one hand, the difficulty of a third party to intercept complete information from the communication data can be greatly increased, so that the third party is difficult to crack signals via ultrahigh performance calculation; and on the other hand, even if enough information is intercepted by the multiple channels, complete effective data is difficult to be extracted from the encrypted fragmentization information, and it is difficult to recombine and recover the original data, therefore the security is improved.

The invention discloses a secret communication method based on an IP address hopping fragmentization transmission technology. One IP address is converted into multiple IP addresses through an IP address conversion module at an information sending end; then, communication data is dispersed into information fragments and transmitted through the multiple IP addresses; at an information receiving end, the information fragments transmitted through the multiple IP addresses are received, and re-integrated according to a fragmentization rule when a signal is sent; and thus, the multiple IP addresses are converted into one IP address. The number of the IP addresses, through which the information fragments pass, in a communication process and transmission by IP selection are determined by a secret key; by means of the secret communication method disclosed by the invention, the difficulty that complete information of the communication data is intercepted and captured by a third party is increased; and thus, the security is improved.
