Embodiment
In order to make content of the present invention clearly with understandable, below in conjunction with specific embodiments and the drawings, content of the present invention is described in detail.
Fig. 1 schematically shows the schematic diagram being encrypted the system securely communicated according to the preferred embodiment of the invention by random segment; And Fig. 2 schematically shows the flow chart being encrypted the system securely communicated according to the preferred embodiment of the invention by random segment.
As depicted in figs. 1 and 2, information communication system comprises the first communication device 10 with first memory 11 and the secondary communication device 20 with second memory 21 according to the preferred embodiment of the invention.Thus, encrypt by random segment the system securely communicated according to the preferred embodiment of the invention to comprise:
First step S1: store the first dispatch list 12 in the first memory 11 of first communication device 10, and in the second memory 21 of secondary communication device 20, store the second dispatch list 22, wherein the first dispatch list 12 and the second dispatch list 22 all store multiple channel information (the first channel 110 such as shown in Fig. 1, the channel information of second channel 120 and the 3rd channel 130), encode with each the corresponding signal segment in described multiple channel information, and with each the corresponding enciphered message in described multiple channel information, and described enciphered message represent corresponding to described multiple channel information signal in the encrypted and another part unencryption of a part,
Preferably, the first dispatch list 12 is identical with the second dispatch list 22.
Such as, the first dispatch list 12 and the second dispatch list 22 are as shown in table 1 below:
Table 1
When the example of table 1, first channel information (corresponding to the first channel 110) is corresponding to signal segment coding " 1 ", second channel information (corresponding to second channel 120) is corresponding to signal segment coding " 3 ", and the 3rd channel information (corresponding to the 3rd channel 130) is corresponding to signal segment coding " 2 "; Wherein, enciphered message represents that only having second channel information to have employed WEP (Wired Equivalent Privacy) technology has carried out encryption.
Second step S2: first communication device 10 is divided into multiple signal segment the signal that will send and is followed successively by described multiple signal segment distributing signal section coding, the quantity of wherein said multiple signal segment corresponds to the quantity of described multiple channel information, and the length of wherein said multiple signal segment to account for the percentage of the whole length of the described signal that will send incomplete same; Such as, when the signal that will send be divided into the first signal segment, secondary signal section and the 3rd signal segment, the length of the first signal segment, secondary signal section and the 3rd signal segment accounts for that the percentage of the whole length of the described signal that will send is incomplete same can be respectively 30%, 30% and 40%.
Third step S3: described multiple signal segment is passed to secondary communication device 20 by mode that first communication device 10 utilizes the channel corresponding to described multiple channel information to encrypt with local channel based on the first dispatch list 12 according to enciphered message respectively, wherein the signal segment coding of the signal segment that transmits of each channel is encoded consistent with the corresponding signal section of the described multiple channel information corresponding to this channel in the first dispatch list 12;
When the example of table 1, the first channel 110 transmission of signal section is encoded to the signal segment of " 1 ", and second channel 120 transmission of signal section is encoded to the signal segment of " 3 ", and the 3rd channel 130 transmission of signal section is encoded to the signal segment of " 2 "; And only second channel information have employed WEP technology and carries out signal transmission.
4th step S4: receive described multiple signal segment at secondary communication device 20, according to the second dispatch list 22, the signal segment received from the channel carrying out signal segment transmission in the mode of encryption is carried out corresponding decryption processing, and encode for the signal segment received from the channel corresponding to each channel information distributes the signal segment corresponding in the second dispatch list 22 with this channel information;
When the example of table 1, secondary communication device 20 is signal segment distributing signal section coding " 1 " received from the first channel 110, for signal segment distributing signal section coding " 3 " section received from second channel 120, it is signal segment distributing signal section coding " 2 " received from the 3rd channel 130.
5th step S 5: the described multiple signal segment received according to distributed signal segment coding assembling secondary communication device 20 at secondary communication device 20.
Thus, encrypted in the system securely communicated according to the preferred embodiment of the invention by random segment, by signal being split into the different multiple signal segments of length, and the different signal segment after utilizing different channels transmission to break, and receiving terminal according to preset schedule information carry out signal assembling and deciphering with restore information, thus even if signal is intercepted in transmittance process, because how the side of intercepting cannot know in order and signal Length Ratio is assembled and decrypted signal thus recovering signal, thus still leakage of information can not be caused; Should encrypt by random segment the system securely communicated thus and realize secure communication with simple means and low cost.
In addition, it should be noted that, unless stated otherwise or point out, otherwise the term " first " in specification, " second ", " the 3rd " etc. describe only for distinguishing each assembly, element, step etc. in specification, instead of for representing logical relation between each assembly, element, step or ordinal relation etc.
