Description
Technical field
The present invention relates to field of communication technology, in particular to a kind of enciphered data transmission method.
Background technique
Currently, higher and higher to the requirement of safety in data transmission procedure.In existing data transmission technology, one
As the safeties of data guaranteed using following two mode, it may be assumed that transmitted again after encrypting clear data, or in transmission number
Authentication is carried out to the both sides of transmission data in advance according to preceding.It can be used alone above-mentioned a certain mode in the prior art, but
Usually two ways is used in combination, i.e., by clear data encrypted transmission after both sides' authentication.By clear data plus
The specific practice transmitted again after close is: transmitting terminal utilizes some key, using security algorithm to key and clear data
It is handled, obtain encryption data and is transferred to receiving end；After receiving end receives encryption data, using identical key and peace
Encryption data is decrypted in full algorithm, restores clear data.In existing data transmission technology, based on the various safety of realization
The approach of purpose and various demands for security are different, produce various security algorithms.According to the height of security level, various encryptions are calculated
The complexity of method is different.But a certain kind is applied, the security algorithm and key that data encryption uses all immobilize
, therefore the safety of data transmission is lower.For transmitting the instruction of a certain item because security algorithm that same instructions use and
Key is fixed and invariable, so if this instruction is cracked in certain primary transmission, cracker obtain security algorithm and
Key, then cracker may be by identical security algorithm and key cracks this finger in transmission each time later
It enables.It can be seen that the security algorithm and key in available data transmission technology immobilize so that data transmission safety compared with
It is low.Especially apply in intelligent security guard field, with the extensive use of smart home, smart home system usually its transmitting terminal and
The data of receiving end transmission mainly pass through DES, AES, RSA, MD5 and carry out encrypted transmission, and data are in single channel transmission, logarithm
According to being encrypted, it is easy to be cracked after being stolen by criminal, such criminal can arbitrarily control intelligent family
Product is occupied, crime of entering the room is carried out, the property and personal safety of user are posed a great threat.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes that a kind of data transmission security is high, reduces data by criminal
The probability of interception, data encryption are difficult to the enciphered data transmission method cracked.
To solve this technical problem, the present invention takes following scheme: a kind of enciphered data transmission method, including following step
It is rapid:
S1, byte number is set as Ni2Message body in Ni4The transmission of a channel unrestricted choice, using timer conter generate one with
Machine number Ni1, the byte number that will be transmitted is Ni2Message body according to random number Ni1It is split as N at randomi3Section message body segment data
Packet, works as random number Ni1≤ message body byte number Ni2When message body split number of segment Ni3=random number Ni1Section, works as random number Ni1>=message
Body byte number Ni2When message body split number of segment Ni3=message body byte number Ni2/ 2 sections, wherein Ni1、Ni2、Ni3And Ni4It is natural number
And Ni4For the natural number greater than 1；
S2, the N for completing the fractionation of previous stepi3Section message body segment data packet carries out random incorrect order arrangement using encoder
Dynamic encryption and random multi-channel transmission are carried out again, which is by the N after the arrangement of random incorrect orderi3Section message body segments
It carries out rolling code encryption and exclusive or encryption respectively according to packet；Random multi-channel transmission refers in Ni4It is randomly selected in a total channel
Ni5A channel, wherein 1≤draw random channels number Ni5≤ total channel number Ni4, Ni5For natural number, by each section of completion dynamic encryption
Ni3Section message body segment data packet is assigned randomly to selected Ni5Data are transmitted in a channel and by packet structure,
In the content of each section of message body segment data packet include: packet serial number rolls serial number, incorrect order queueing discipline, next section of message body point
This segment data split by the channel of segment data packet transmission and message body；
S3, message body reduction, receiving end receive each section of message body segment data packet and store and decrypted by decoder and restore
The true value of data recombinates the segmentation of the message body in each section of message body segment data packet by packet serial number, incorrect order queueing discipline
Data are sequentially spliced into complete message body data.
Further, in the step S1 fractionation of message body random number Ni1It is one generated at random by timer conter
A≤20 natural number, every section of message body segment data include at least the message body data of 1 byte.
Further, it to carry out first looking for net simultaneously in transmitting terminal all channel when random multi-channel transmission is sent for the first time in step S2
And it is in same channel with receiving end, then tell receiving end frequency hopping to next reception channel, receive real message body segmentation
Data packet.
By using preceding solution, the beneficial effects of the present invention are: being torn open at random by the data that will be transmitted
It is divided into multistage message body segment data packet, then multistage message body segment data packet is subjected to random incorrect order arrangement and carries out dynamically adding again
Close and random multi-channel transmission, then each section of message body segment data packet is recombinated by packet serial number, incorrect order queueing discipline in receiving end
Interior message body segment data is sequentially spliced into complete message body data, and data are transmitted using a variety of cipher modes and divided
Section incorrect order is transmitted and is transmitted at random to the message body segment data packet of segmentation using multichannel, so that encryption number of the invention
Have data transmission security is high, reduces data to be difficult to crack by probability that criminal intercepts, data encryption according to transmission method,
The security risk for eliminating the manipulations that are cracked such as the smart home product of intelligent safety and defence system, can wide popularization and application.
Detailed description of the invention
Fig. 1 is the flow diagram of the embodiment of the present invention.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention is further described, is segmented in the present invention to the message body of transmission
Data packet roll code encryption and exclusive or encryption mode be existing cipher mode thus the embodiment of the present invention not to it
