Fig. 2 is the relation of character bit in the packet of duplicate contents and real data byte sequence.
Embodiment
Technical scheme of the present invention is further described below in conjunction with accompanying drawing embodiment, but described in claimed scope is not limited to.
Based on an information coding transmission method for the UPD network transmission protocol, it comprises following steps:
(1), definition data transmitting terminal A, data transmitting terminal A are the equipment of the WLAN (wireless local area network) having accessed encryption and adopt the connectionless UDP network transmission protocol to other network addresss transmission information;
(2), definition data transmitting terminal B, data transmitting terminal B are that the while of not accessing aforementioned WLAN but have the equipment of radio network functions, data transmitting terminal A and data transmitting terminal B is in identical wireless network signal coverage;
(3), data transmitting terminal A and data transmitting terminal B makes an appointment: preset a time span section n, preset the information of the byte length sent in this time span section n, the different characteristic value m of the s position of each byte of the data byte sequence of data transmitting terminal B is mail to according to the different length s definition of the real data byte sequence mailing to data transmitting terminal B, m is 0 or 1, the length such as mailing to the data in a packet of data transmitting terminal B is 6, the 6th that then can define the first character joint of the data byte sequence mailing to data transmitting terminal B is 1, or also can be expressed as 0 according to making an appointment, then the length mailing to the data in a packet of data transmitting terminal B is 5, the 5th that can define the first character joint of the data byte sequence mailing to data transmitting terminal B is distinguish the characteristic value that length is the byte information of 6,
(4), set up the mapping relations of transmitting terminal A and data transmitting terminal B: according to characteristic value m, data transmitting terminal A repeatedly sends the data of equal length s to data transmitting terminal B in predetermined time section n, complete the transmission communication of UPD data, as Fig. 1, in packet and real data byte sequence, character bit hints obliquely at relation schematic diagram, packet A, B, C, duplicate contents is not had between D, packet A repeatedly sends the data of equal length S1 in predetermined time section n according to byte length S1, packet B repeatedly sends the data of equal length S2 in predetermined time section n according to byte length S2, as Fig. 2, packet A, duplicate contents is had between B, packet A is equal with packet B byte length, repeatedly sends packet A and the packet B of equal length in predetermined time section n.
The described real data byte length mailing to data transmitting terminal B is less than the byte length presetting and send in this time span section n.
When existing data transmitting terminal A needs to send information to data transmitting terminal B, data transmitting terminal A adopts the connectionless UDP network transmission protocol to send information to data transmitting terminal B, as: 255.255.255.255, data transmitting terminal B is because be in wireless network signal coverage so can listen to the information mailing to aforementioned network address, because data transmitting terminal A is in the wireless network of encryption so its all information sent are all encrypted just sends afterwards, therefore the information mailing to aforementioned network address that data transmitting terminal B obtains is encrypted information, again because data transmitting terminal B does not add the encrypted wireless network identical with data transmitting terminal A, the key of encryption wireless network is not known in advance yet, therefore data transmitting terminal B is not by decrypted the information that data transmitting terminal A sends.
And the equipment in the wireless network of encryption that the invention enables can adopt connectionless mode to send information directly to the equipment beyond network, the cipher mode of Dynamic data exchange in the network information of actual transmission is made by implication data mode, relation of hinting obliquely between the data simultaneously sent and actual data content is preset by data transmitting terminal A and data transmitting terminal B, therefore this method has stronger confidentiality, even if third party has intercepted and captured packet, and know it is adopt this coding and transmission method, also the content that data transmitting terminal A sends to data transmitting terminal B cannot be understood.
In this method, when recipient receives the data of identical numerical value, only the reliability that can resolve to increase transmission repeats the data of transmission, can not because of the information analysis of identical numerical value being different information thus producing to obscure, comparatively simple method is used to connect in nothing, nonreply, exist in the network environment of packet loss and reliably carry out information transmission, without any need for special device or special software on the data transmitting terminal A of transmission information, as long as it can send UDP message bag to particular address, and this requires that all Wireless Communication Equipment all possess, without any need for special device on the data transmitting terminal B received information, as long as it can be intercepted the packet that mails to particular network address and can content in resolution data bag.Therefore the scope of application of this method widely.
