Abstract
The invention discloses a mobile phone communication enciphering mechanism based on a multi-channel signal fragmentation transmission technology. The method comprises the following steps: at an information transmitting end, scattering service data each time into lots of information fragments, mixing the information fragments with random data and sending the mixed data out through two or more SIM cards by a mobile phone antenna; at an information receiving end, receiving these information fragments through the same number of SIM cards and integrating and restoring the original complete service data from the fragment information. The mobile phone communication enciphering mechanism adopted in the invention has the advantages that the difficulty of an eavesdropper in intercepting and capturing complete information can be increased greatly so that the eavesdropper cannot decipher signals through super high performance computing on one hand; even though the eavesdropper intercepts and captures enough information through multi-channel eavesdropping, valid data can be hardly extracted from the enciphered data fragments and the original data cannot be recombined or restored, either.
