Embodiment
The invention provides a kind of retransmission technique scheme that realizes content without the information of change, can guarantee the authenticity of institute's forwarding information.Core concept of the present invention is, in the address field of forwarding information or the information content, add one " trust field ", information centre is after detecting this trust field, the received all information of information transmitting terminal that the information of same of this forwarding is stored in the information centre is mated, the information content unanimity of the two, information centre is when issuing this trust information, with a predefined idiosyncrasy credit number as information transmitter, and identify the direct sender of information and indirect sender, the content that information receiving end can be judged this information according to this special number is without change, and can know the true source of this forwarding information.
Fig. 1 has represented the composition of information centre in the information repeater system of the present invention, comprises information receiving module, message processing module, memory module and information sending module.
Information receiving module is used to receive the information that information transmitting terminal is transmitted, and described forwarding information is passed to message processing module.
Core component when message processing module is information centre's process information forwarding, main analysis, the processing that realizes the forwarding information content, and all information that canned data transmitting terminal in the information transmitted and the memory module is received mate, and whether the content of judging the two unanimity.
Memory module is used for when message processing module matches the identical information content of the information content with this forwarding information, preservation information, the information number, the information content, information source label, information transmitter and the information receiver that preserve this forwarding information.
Information sending module is used for when message processing module matches the identical information content of the information content with this forwarding information, the information content of described forwarding information with the source set of tags is synthetic issues content, is handed down to described information receiving end.
Information centre's structure chart of contrast Fig. 1, and with reference to the data handling procedure of Fig. 2 information centre, when the virgin information of forwarding information content, comprise the steps:
In the process of forwarding information content without transition information, information transmitting terminal encapsulates recipient's address, making information centre can tell this is the request that an information content is transmitted without the information of changing, in encapsulation process, add one " trust field " in the information receiving end address field earlier, then " trust field " and recipient address are encapsulated, transmit to be different from general information.
After the information receiving module in the information centre receives this forwarding information, send this forwarding information to message processing module, handle by message processing module.
Message processing module is at first unpacked to recipient's address field of the forwarding information that receives, if do not include " trust field " in the discovery address field, then transfer general information to and transmit processing procedure, as include " trust field ", then the information that receives is carried out matching treatment, judge whether the content of this forwarding information has change.Message processing module calls all received information of direct sender of this forwarding information to memory module, and carry out content match with this forwarding information one by one, if can find and the identical match information of this forwarding information content, show that then the direct sender of this forwarding information does not make amendment to this information; Otherwise just show it is common forwarding, transfer general information to and transmit processing procedure.
The content of confirming this forwarding information is without after changing, and information centre produces a unique information number, registers to the memory module corresponding field, shows that this is the new information of bar.The information content of this forwarding information is registered to the memory module corresponding field, and, register to the memory module corresponding field pairing indirect sender of match information and the source label of direct sender as information.Wherein, separate with special symbol between sender and the direct sender indirectly, separator is set by information centre.While can mark indirect sender and direct sender in order to distinguish indirect sender and direct sender, and concrete mark is set by information centre, distinguishes indirect sender and is also set by information centre with direct sender's mark.
Because the content of this forwarding information is without change, therefore, information centre has defined special " a trust number " and has registered to the corresponding field of memory module as information transmitter, is trusty to represent this information, and the source is real.Having defined 86xxx as information centre is the sender that content is transmitted without the information of changing, in case information receiving end receives that when information transmitter was the information of 86xxx, the content that can judge this information was without change.
Message processing module is unpacked without recipient's address field of the forwarding information of changing to the information content that receives, and will trust field and peel off, and the residue field registers to the storage module corresponding field as the recipient of information.
So far, flow chart of data processing finishes, and then carries out the flow process that issues of information.
Issue in the flow process in information, whether the source label field of at first judging corresponding information is empty, if empty, then with the information content as issuing content; Otherwise,, wherein separate with special separator between the information content and the source label the information content and the synthetic content that issues of source set of tags, separator is set by information centre, next be exactly the process that issues of information, this issues the process unanimity with existing information, no longer describes at this.
Table 1 is the information format of information centre.
| Information number | The information content | The source label | The sender | The recipient |
Table 1
Table 2 is the virgin forwarding instance of the information content.
Table 2
As shown in table 2, information number, the information content, source label, sender and recipient are the fields in the memory module.First row refer to the transmit operation of information in the table, and virgin forwarding of the information content and common forwarding two classes are arranged.If common information is transmitted, then its source label field is empty, and sender's field is common station address; If the virgin forwarding of the information content, then its source label field is not empty, and the information transmitter field is special number, as " 86xxx " of supposition in the table, this sender's field is the specific information number that information centre sets, and the information content of representing this forwarding information is without change.
When information receiving end was received forwarding information, colon was the separator of the information content and source label, and comma is the inside separator of source label, and separator all is that information centre is predefined, is not limited to colon and comma.Colon is divided into two parts to the content that issues that the recipient receives, the front is the information content, and the back is the source label, is exactly the source of information, i.e. sender and directly sender indirectly.In table, add special marking " T " before the direct sender, add special marking " F " before the sender indirectly, concrete mark is set by information centre, and it is just in order to distinguish direct sender and indirect sender.Certainly, the front and back position of the information content and source label can exchange, and directly sender and indirect sender's position also can exchange.
By table as seen, issue and carry specific separator or directly sender, sender's mark indirectly in the content even information receiving end is received, still can not confirm that this information is (for example * * * 3 information) trusty, must check also whether the information transmitter that receiving terminal shows is the idiosyncrasy credit number that information centre sets.So information receiving end is received issues and contain separator and directly sender, sender's mark indirectly in the content, the content that can not determine this forwarding information is without change.
, except the address to the recipient encapsulates, also can the information content that send be encapsulated during without the information of changing in the forwarding information content, making information centre can differentiate this is the request of a forwarding information content without the information of changing.
, the content that sends is encapsulated during without the information of changing in the forwarding information content, making information centre can tell this is the request of a forwarding information content without the information of changing.In encapsulation process, add one " trust field " in information content field earlier, then " trust field " and the information content are encapsulated, to be different from common forwarding.
The information format that is stored in information centre is as shown in table 1, and information centre's data handling procedure as shown in Figure 2.
After information receiving module receives information, with regard to the flow process of start information processing module deal with data.
Message processing module is at first unpacked to the content of the information of receiving, if find to contain " trust field " in the content field, show then that the sender asks be the forwarding information content without the information of changing, and will trust the fractionation of the field and the information content simultaneously.Otherwise just show it is common forwarding, transfer to and carry out the general information processing procedure.
Message processing module carries out matching treatment with regard to the information content that receives, and judges whether the content of this forwarding information has change.Message processing module calls all received information of direct sender of this forwarding information to memory module, and carry out content match with this forwarding information one by one, (here be meant if in memory module, can inquire through unpacking process with this forwarding information content, peel off the content field after " trust field ") identical match information, show that then the direct sender of this forwarding information does not make amendment to this information; Otherwise just show it is common forwarding, transfer general information to and transmit processing procedure.
Information centre produces a unique information number to this forwarding information, registers to the memory module corresponding field, shows that this is the new information of bar, and will be through the process of unpacking and the information content peeled off after " trust field " register to the memory module corresponding field.
Information centre registers to the memory module corresponding field with pairing indirect sender of match information and the source label of direct sender as information.Wherein, separate with special symbol between sender and the direct sender indirectly, separator is set by information centre, distinguishes indirect sender and direct sender's mark and is also set by information centre.
Special " trust number " of information centre definition registers to the corresponding field of memory module as information transmitter, is trusty to represent this information, and the source is real.Having defined 86xxx as information centre is the sender that the information content is transmitted without the information of changing, in case information receiving end receives when information transmitter is the information of 86xxx that the content that can judge this information can be trusted without change.
Information centre is directly with the address registration of the information receiving end corresponding field to memory module.
So far, information centre's flow chart of data processing finishes, and carries out the flow process that issues of information with that, and technical scheme is same as above, omits at this.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
