Embodiment 1：
The present invention designs a kind of real-time intelligent anti-theft magnetic snap system based on low-power consumption bluetooth, using signal source, antitheft

The purpose of detection is covered, as shown in Figure 1, Figure 2, Figure 3 shows, especially using following setting structures：It is provided with and is believed each other by bluetooth
Number signal source communicated, decoder, anti-theft magnetic snap, detector and precaution device；
The signal source by into broadcast singal coverage anti-theft magnetic snap send encryption antitheft information, the scope
If anti-theft magnetic snap listens to broadcast singal and just enters next listening period after being verified correctly by AES；The signal
If the continuous 2 monitorings failure in source receives error signal, it is judged as illegal operation, alarm at once is pointed out；
The decoder is realized to anti-by the decoded signal of the anti-theft magnetic snap transmission encryption into broadcast singal coverage
Steal the identification of magnetic clasp take-off legitimacy；If the decoder does not receive decoded signal or receives error signal, anti-theft magnetic snap will be reported
Alert prompting；
The detector realizes lossless blind detection by sending the detection signal of encryption into broadcast singal coverage；
Specifically, the detection signal that the detector can send encryption to the anti-theft magnetic snap in broadcast singal coverage is realized to case and bag
Internal lossless blind detection, it is to avoid legal dispute；
The precaution device realizes warning function by sending the alarm signal of encryption into broadcast singal coverage；
When the anti-theft magnetic snap is destroyed by unlawful violence, will be triggered alarm；
The function expression of the AES is as follows：
Y=f (x1,x2,x3)；
Wherein independent variable x1, x2, x3User name, three vectors of user cipher and MAC Address are corresponded to respectively, and dependent variable y is then
Correspondence broadcast vector.
In design in use, the indicator lamp is according to the display modes of different colours or different frequency, cue source or
Decoder or sensors work are in what state；
The present invention realizes signal source, decoder, detector and antitheft using the pattern of the multiple anti-theft magnetic snaps of terminal-pair
Bluetooth communication between magnetic clasp.
The present invention handles numerous anti-theft fastener terminals due to needing, therefore can not realize related letter by point-to-point connection
The transmission of breath, therefore the transmission of confidential information can only be realized by broadcasting, so as to reach antitheft purpose.
In specific implementation, the difficult point of real-time intelligent anti-theft magnetic snap system is that how to distinguish forgery terminal sends same
Broadcast, because any data are passed by plaintext after processing, is easily read and forges, and information is by anti-theft fastener
Decrypted again with same method after receiving, be so that cannot be distinguished by true and false terminal (signal source, decoder, precaution device, detection
Device).
Solution annual reporting law has following several：
1st, launch terminal is encrypted data A by the pseudo-random function changed over time, and then anti-theft magnetic snap receives number
By same functions carry out inverse process according to rear, but because anti-theft magnetic snap is high to power consumption requirements, and when and work, when and dormancy, when
Clock can not accomplish synchronous with terminal, therefore such algorithm is unworkable.
2nd, the MAC Address of terminal is globally unique, it is impossible to forged, therefore anti-theft magnetic snap can pass through the identification to MAC
To distinguish the true and false, but on condition that each anti-theft magnetic snap is required for the MAC of all terminals writing non-volatile deposit using preceding
Reservoir, and midway often increases a terminal, is required for all anti-theft fasteners carrying out write operation, otherwise anti-theft magnetic snap will be considered to
It is new to add terminal to forge terminal；Therefore there is a situation where that process is extremely complex, it is same unworkable.
3rd, because user profile is concealed to external world, MAC is unique again, if therefore carrying out user profile and MAC
Data after related operation ensure that the uniqueness of broadcast data as broadcast data, and each different MAC Address is corresponded to
Unique broadcast, accordingly even when having forged broadcast, anti-theft magnetic snap is after relevant broadcasts are received, and MAC corresponding with signal enters
The broadcast obtained after the processing of the same computing of row is also inconsistent, that is, it is pseudo-terminal to demonstrate.
User name and password are all concealed to external world in user profile, therefore can be improved using the two all as variable
Security.
Its workflow is as follows：
True terminal procedures such as Fig. 4, forges terminal procedures such as Fig. 5；
Even if it will be evident that having forged broadcast from Fig. 4 and Fig. 5, but because MAC can not be forged, therefore receive
It is unequal to broadcast the broadcast calculated with anti-theft magnetic snap according to data.
By being described above, the AES can be summarized as follows：
Set first broadcasting format as：
| Data length | Broadcast type | Terminal type | Operation result | Other information |
Wherein, 1. data length：The byte length entirely broadcasted is described.
2. broadcast type：By setting particular type to be shielded incoherent equipment.
3. terminal type：By setting particular type to differentiate, broadcast is signal source, decoder, precaution device or detector,
And whether corresponding operating is correctly performed according to operation result.
The function expression of AES is as follows：
Y=f (x1,x2,x3)
Wherein independent variable x1, x2, x3User name, three vectors of user cipher and MAC Address are corresponded to respectively, and dependent variable y is then
Correspondence broadcast vector.
When user name and user cipher vector are determined, it is assumed that should be obtained broadcasting vectorial y by real MAC address1；If now
There are MAC1 addresses (whether the MAC for being not aware that reception for anti-theft magnetic snap is true, it is therefore assumed that being different address MAC1) to exist
Broadcast vector y1, when anti-theft magnetic snap receives MAC1 vectors and broadcast vector y1When, y will be obtained with same encryption function2,
If y1=y2, then it is MAC1=MAC；If y1！=y2, then MAC1！=MAC, to forge address.
Therefore, if user name is with being correctly to be broadcasted only according to MAC Address under the vectorial unknown situation of user cipher
Vector, so as to reach encryption purpose.
Specific ciphering process is as follows：
If user name has n, password has m, n>M, and n<=Len-3 (Len is data length), MAC are the ground of terminal
Location, for convenience of demonstration, it is assumed that n>6 (MAC length).Therefore it is settable：
User name vector x1(being all binary system):It is common 8n：
A=(A01A02A03A04A05A06A07A08
A11A12A13A14A15A16A17A18........An1An2An3An4An5An6An7An8)
Crypto vector x2(being all binary system):It is common 8n, the benefit 0 more than 8m：
B=(B01B02B03B04B05B06B07B08B11B12B13B14B15B16B17B18........00000000)
MAC vector x3(being all two progress)：It is common 8n, the benefit 0 more than 48：
C=(C01C02C03C04C05C06C07C08C11C12C13C14C15C16C17C18........00000000)；
Operation result y1=f (x1,x2,x3)=f (A, B, C)=A*B*C=

In have result of calculation spilling, then automatic interception most least-significant byte is used as the entry value；For convenience, tri- vectors of ABC can take same solid
Measured length, the determination of convenient broadcast length.
Verifying broadcasts process：
If the operation result that anti-theft magnetic snap is extracted from the signal received is y1, it is C1 to broadcast corresponding terminal address
(in order to distinguish C, being temporarily set to C1), the then result that anti-theft magnetic snap is obtained by terminal address C1 using same algorithm：
y2=f (x1,x2,x3)=f (A, B, C1)=A*B*C1
