The Information Security of tooth frequency hopping mechanics of communication.
As a specific example, it is to be realized by the frequency hopping of 0~79 channel this 80 channels, still in Bluetooth system
During frequency hopping, data both sides can communicate update frequency hopping table in real time, the selection and update of that frequency hopping frequency point can will also be sent out
Send in the air give other side execute.
The frequency hopping table structure being shown referring to Fig. 6, Fig. 6 after increasing frequency-hopping encryption scrambling unit, wherein frequency-hopping encryption
Scrambling unit is used to, by preset algorithm (i.e. preset-key), be ranked up frequency hopping table, generates frequency hop sequence table.
The preset algorithm when two wireless devices link for the first time, system interrogation whether secure link.The calculation after determination
The frequency hop sequence that method mechanism can be directed to the available channel inside the frequency hopping table of real-time update variation is encrypted, and the algorithm is as secret
The presence of key is supplied to pairing both sides, subsequent data transmitting and receiving all to transfer the Secret key arithmetic and carry out data encryption and decryption.
The secret key can be as a kind of Encryption Algorithm of bluetooth frequency hopping table real-time update, then the next Frequency point that will be skipped to of bluetooth, only
There is the user for possessing the secret key that can obtain, the possibility that remaining back door obtains correct frequency point is 1/80.That is, meeting
So that the physical layer data for illegally obtaining taker basis is all difficult to get to, less with the violence demodulation for proceeding to session layer data
In.Namely the frequency hopping table of bluetooth is encrypted, the possibility of user data is obtained to reduce illegal person from physical layer.Such as
Shown in Fig. 7, Fig. 7 is the Bluetooth transmission model after increasing frequency-hopping encryption scrambling unit, wherein in band spectrum modulation and despreading
In jump frequency synthesizer in the process, frequency hop sequence encryption key is respectively set, to obtain identical frequency hop sequence.
Below with two equipment, for bluetooth A and bluetooth B are respectively as main control end and controlled terminal, introduce the present invention and implement
The Bluetooth connecting method that example provides；Referring to Fig. 8, Fig. 8 is when establishing bluetooth connection for the first time, and preset-key is sent to indigo plant by bluetooth A
Tooth B, the two store preset-key respectively.
Fig. 9 is the two interactive process schematic diagram：
What 901, bluetooth A received bluetooth B establishes Bluetooth connection request.
902, bluetooth A determine whether bluetooth B meets default security requirement：
If not satisfied, 903 are thened follow the steps, the connection request of refusal respond bluetooth B.
If satisfied, then executing 904, the encryption key generation unit of bluetooth A stores preset-key, and executes 905, by preset-key
It is sent to bluetooth B.
Bluetooth B executes 906, stores preset-key.
In above-mentioned example, from the bottom of Bluetooth wireless transmission data, i.e. physical layer has carried out data encryption, allows illegal nothing
Line number can not obtain the frequency point of bluetooth frequency hopping according to winner, to prevent the illegal acquisition of wireless data from physical layer.
