Abstract
The object of the present invention is to provide a kind of wireless networking communications methods for preventing beacon from attacking, which comprises the following steps: step S1: regulation beacon transmission interval<T1, T2>, T2>T1；Step S2: next beacon is randomly selected in<T1, T2>section and sends interval Tx；Step S3: containing the transmission interval Tx of next beacon in each frame beacon content, i.e., next beacon will emit after the Tx time, T1 < Tx < T2；Step S4: the part at least including next beacon transmission interval information to beacon encrypts；Step S5: when node inquires beacon message to adjacent node, at least to the Partial encryption in adjacent node return information including beacon transmission interval information；Step S6: in wireless self-networking, network node carries out the transmission of networked beacons, broadcast according to step S1-S5.The present invention by by beacon is random and encrypted transmission, will so that beacon to send rule unpredictable, thus avoid beacon attack.
Description
Technical field
The invention belongs to fields of communication technology, and in particular to the wireless networking communications method that one kind can prevent beacon from attacking.
Background technique
Communication beacons are key messages in wireless networking communications, and the synchronization, coordination and pipe of wireless group network may be implemented
Reason.In conventional wireless networking communications, beacon uses and regularly sends mechanism；And network attack person receives beacon just by repeatedly tracking
It can be found that the transmission rule of beacon.Network attack person only needs by interfering beacon emissions --- in networked beacons broadcast moments
Issue interference signal or emit pseudo- beacon --- thus make wireless networking network node that can not be normally received beacon, it cannot be normal
It works and is paralysed.
Summary of the invention
In view of this, the present invention provides a kind of wireless networking communications method that can prevent beacon from attacking, when sending beacon
Between can not predict the attacks such as can not be tracked, be intercepted, forged.
The present invention is implemented with the following technical solutions: a kind of wireless networking communications method for preventing beacon from attacking, feature
It is, comprising the following steps: step S1: regulation beacon transmission interval<T1, T2>, T2>T1；Step S2: in<T1, T2>area
It is interior to randomly select next beacon transmission interval Tx；Step S3: the transmission of next beacon is all contained in each frame beacon content
It is spaced Tx, i.e., next beacon will emit after the Tx time, T1 < Tx < T2；Step S4: at least beacon is sent comprising next beacon
The part of interval information is encrypted；Step S5: when node inquires beacon message to adjacent node, at least adjacent node is returned
It writes in reply and sends the Partial encryption of interval information in ceasing comprising beacon；Step S6: in wireless self-networking, network node is according to step
S1-S5 carries out the transmission of networked beacons, broadcast.
Further, the method that randomly selects in step S2 is white Gaussian noise distribution or pseudo-random distribution.
In an embodiment of the present invention, node is sent out by broadcasting beacon querying command to adjacent node to obtain next beacon
Send interval information.
In an embodiment of the present invention, the encryption method of step S4 is AES, 3DS or DES.
Compared with prior art, the invention has the following advantages that step is simple, it is easily operated；It crosses beacon is random and adds
Close transmission is incited somebody to action so that beacon transmission rule is unpredictable, thus avoids beacon attack.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
The present invention provides a kind of wireless networking communications method for preventing beacon from attacking, which comprises the following steps:
Step S1: regulation beacon transmission interval<T1, T2>, T2>T1；Step S2: next letter is randomly selected in<T1, T2>section
Mark sends interval Tx；Step S3: containing the transmission interval Tx of next beacon in each frame beacon content, i.e., next beacon will
Emit after the Tx time, T1 < Tx < T2；Step S4: the part at least including next beacon transmission interval information to beacon adds
It is close；Step S5: it when node inquires beacon message to adjacent node, is at least sent in adjacent node return information comprising beacon
The Partial encryption of interval information；Step S6: in wireless self-networking, network node carries out the hair of networked beacons according to step S1-S5
It send, broadcast.Flow chart is referring to Fig. 1.It, can also be with except to including that next beacon sends the part of interval information and encrypts to beacon
Beacon other information is encrypted according to user's specific requirements.
Further, the method that randomly selects in step S2 is white Gaussian noise distribution or pseudo-random distribution.
In an embodiment of the present invention, node can obtain next letter by broadcasting beacon querying command to adjacent node
Mark sends interval information.
In an embodiment of the present invention, the encryption method of step S4 is AES, 3DS or DES.Also other encryptions be can choose
Mode.
In conventional wireless ad hoc network, beacon generallys use and can predict mode and send, and can multiply it to network attack person in this way
Machine, network attack person can obtain beacon transmission rule by monitoring, and then when beacon is sent, by blocking, interfering
Implement network attack with modes such as forgeries.Using technical solution provided by the invention by beacon is random and encrypted transmission, will so that
It is unpredictable that beacon sends rule, thus avoids beacon attack.
Those skilled in the art can do this specific embodiment under the premise of without prejudice to the principle and substance of the present invention
It various modifications or supplement or is substituted in a similar manner out, but these changes each fall within protection scope of the present invention.Cause
This technology of the present invention range is not limited to the above embodiment.
