Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, below will be to prior art and enforcement
In example, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only
Some embodiments of the present invention, for those of ordinary skill in the art, are not paying creative work
Under premise, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
The process of a kind of data transmission method for voice over Internet that Fig. 1 provides for the present invention
Flow chart；
A kind of structure for the data transmission system of voice over Internet that Fig. 2 provides for the present invention is shown
It is intended to.
Detailed description of the invention
The core of the present invention is to provide a kind of data transmission method for voice over Internet and system, fall
The danger that in low voice over Internet, signaling information is stolen, distorts or eavesdrops, during raising voice transfer
Safety.
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the present invention
Accompanying drawing in embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that
Described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based in the present invention
Embodiment, those of ordinary skill in the art obtained under not making creative work premise all its
His embodiment, broadly falls into the scope of protection of the invention.
The invention provides a kind of data transmission method for voice over Internet, shown in Figure 1,
The flow process of the process of a kind of data transmission method for voice over Internet that Fig. 1 provides for the present invention
Figure；The method includes:
Step s101: be split as the signaling information produced during voice over Internet sorting by preset order
Several packets；
Step s102: several packets are carried out shift sort operation according to preset displacement parameter；
Step s103: be transmitted by several packets after shift sort, receives for data receiver
After several packets, several packets are carried out shift reverse sorting operation according to preset displacement parameter,
Obtain signaling information.
It is understood that signaling information here is one section of character string, include voice messaging.During transmission
The length of the character string owing to transmitting every time requires, therefore needs to split signaling information, then will move
Several packets after the sequence of position are transmitted successively according to the order sequenced.
Wherein, shift sort operation here is actually a kind of cryptographic operation, by according to preset displacement
The order of the original packet of parameter change, thus upset the order of character string in signaling information, the method energy
Enough security breaches largely taking precautions against general internet voice transfer protocol existence itself, reduce mutually
The probability that in networking voice transfer, subscriber identity information or session content are stolen, distort or eavesdrop, greatly
Improve greatly the safety and reliability of voice transfer.And this cryptographic operation is to pass through with corresponding decryption oprerations
Algorithm realizes, and operand is little, and speed is fast, and is prone to software realization.
It should be noted that the data transmission method of the present invention had both comprised the signaling information sending needs and carried out
The process of encryption, had both also comprised the process being decrypted the packet after the encryption received, i.e. the method
It is applied to data sending terminal during voice transfer, is applied to again data receiver during voice transfer.
It is further known that, shift sort operation here includes SF operation and negatively shifted operation.
Wherein, SF operation refers to: several packets after splitting due to signaling information are according to one
Fixed order arrangement, is then a SF by be in the packet at starting position moving to end position,
The size of preset displacement parameter is the number of times of SF.For example, it is assumed that the packet after Chai Fening is
(one packet of a letter representation, wherein, A is the packet at starting position to ABCDEFGH, H
Packet for end position), if preset displacement parameter is 2, then the packet after SF operates
Order is CDEFGHAB.
Corresponding, negatively shifted operation refers to: move to start bit by being in the packet at end position
Putting then for the most negatively shifted, the size of preset displacement parameter is negatively shifted number of times.For example, it is assumed that
Packet after fractionation is that (one packet of a letter representation, wherein, A is for starting for ABCDEFGH
The packet of position, H is the packet of end position), if preset displacement parameter is 2, then negative sense moves
The order of the packet after bit manipulation is GHABCDEF.
Certainly, the present invention does not limit the mode of shift sort operation, and staff can use SF
Operation or negatively shifted operation or use other displacement modes to realize the purpose of the present invention.
As preferably, it is split as the signaling information produced during voice over Internet sorting by preset order
Several packets before also include:
Signaling information is encoded.
Wherein, internet voice transfer protocol is to be BYTE type by the encoding speech information in signaling information
Process.Certainly, type of coding is not construed as limiting by the present invention.
As preferably, also include before several packets after shift sort are transmitted:
Several packets after shift sort are packaged, if corresponding data receiver is to receiving
A dry packet decapsulates.
Wherein, preset displacement parameter here is 2.
Certainly, preset displacement parameter here is to be preset by service end, and its specific size can work people
Member determines according to practical situation, and this is not construed as limiting by the present invention.
The invention provides a kind of data transmission method for voice over Internet, at transmission signaling information
Time, it is possible to several packets split into signaling information according to preset displacement parameter carry out shift sort behaviour
Making, the purpose of this operation is i.e. to be encrypted signaling information, and corresponding data receiver receives several
Also the decryption oprerations first carrying out correspondence after packet could read signaling information, therefore present invention reduces interconnection
The danger that in net voice transfer, signaling information is stolen, distorts or eavesdrops, improves safety during voice transfer
Property.
Present invention also offers a kind of data transmission system for voice over Internet, see Fig. 2 institute
Show, the structural representation of a kind of data transmission system for voice over Internet that Fig. 2 provides for the present invention
