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
5 magnetic clasp, decoder, detector and precaution device terminals realize the covering of total space solid, monitor in real time within whole day 24 hours, 5 ends

The purpose of detection is covered, as shown in Figure 1, Figure 2, Figure 3 shows, following setting structures is especially used: being provided with and believed between 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 area anti-theft magnetic snap send encryption antitheft information, the range
If anti-theft magnetic snap listens to broadcast singal and by just entering next listening period after Encryption Algorithm verifying correctly；The signal
If the continuous 2 monitorings failure in source receives error signal, it is judged as illegal operation, alarm is prompted at once；
The decoder is realized by the decoded signal that anti-theft magnetic snap sends encryption into broadcast singal coverage area to anti-
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 prompt；
The detector realizes lossless blind detection by sending the detection signal of encryption into broadcast singal coverage area；
Specifically, the detector can anti-theft magnetic snap into broadcast singal coverage area send the detection signal of encryption and realize to luggage
Internal lossless blind detection, avoids legal dispute；
The precaution device realizes warning function by sending the alarm signal of encryption into broadcast singal coverage area；
When the anti-theft magnetic snap is destroyed by unlawful violence, will be triggered alarm；
The function expression of the Encryption Algorithm is as follows:
Y=f (x1,x2,x3)；
Wherein independent variable x1, x2, x3Three user name, user password and MAC Address vectors are respectively corresponded, and dependent variable y is then
Corresponding broadcast vector.
In design in use, the indicator light is according to the display modes of different colours or different frequency, standby signal source or
Decoder or sensors work are in what state；
The present invention realizes signal source, decoder, detector and antitheft using the mode of terminal to multiple anti-theft magnetic snaps
Bluetooth communication between magnetic clasp.
The present invention can not realize related letter by point-to-point connection due to needing to handle numerous anti-theft fastener terminals
The transmitting of breath, therefore the transmitting of confidential information can only be realized by broadcasting, to reach antitheft purpose.
In specific implementation, the difficult point of real-time intelligent anti-theft magnetic snap system, which is how to distinguish, forges terminal sending similarly
Broadcast, because any data are gone out by plain text transmit after processing, is easily read and forges, and information is by anti-theft fastener
It is decrypted again with same method after receiving, is that true and false terminal (signal source, decoder, precaution device, detection cannot be distinguished in this way
Device).
Solve annual reporting law there are several types of:
1, launch terminal passes through the pseudo-random function changed over time and encrypts data A, and then anti-theft magnetic snap receives number
According to it is rear by same functions carry out inverse process, but due to anti-theft magnetic snap to power consumption requirements height, and when and work, when and suspend mode, when
Clock can not be accomplished synchronous with terminal, therefore such algorithm is unworkable.
2, the MAC Address of terminal is globally unique, can not be forged, therefore anti-theft magnetic snap can pass through the identification to MAC
Distinguish the true and false, but on condition that each anti-theft magnetic snap requires the MAC of all terminals non-volatile deposit is being written using preceding
Reservoir, and midway one terminal of every increase, require all anti-theft fasteners carrying out write operation, otherwise anti-theft magnetic snap will be considered to
The new terminal that is added is to forge terminal；Therefore there is a situation where that process is extremely complex, it is same unworkable.
3, be to the external world due to user information it is concealed, MAC is unique again, if therefore carrying out user information and MAC
Data after related operation ensure that the uniqueness of broadcast data, each different MAC Address is corresponding as broadcast data
Unique broadcast, accordingly even when forged broadcast, anti-theft magnetic snap after receiving relevant broadcasts, MAC corresponding with signal into
The broadcast obtained after the processing of the same operation of row be also it is inconsistent, that is, demonstrating is pseudo-terminal.
User name and password are all concealed to the external world in user information, therefore the two can be all used as to variable, are improved
Safety.
Its workflow is as follows:
True terminal procedures such as Fig. 4, forges terminal procedures such as Fig. 5；
From Fig. 4 and Fig. 5 it will be evident that even if forged broadcast, but since MAC can not be forged, receive
Broadcast and anti-theft magnetic snap according to the broadcast that data calculate are unequal.
By being described above, the Encryption Algorithm can be summarized as follows:
Broadcasting format is set first are as follows:
| Data length | Broadcast type | Terminal type | Operation result | Other information |
Wherein, 1. data length: the byte length that description is entirely broadcasted.
2. broadcast type: being shielded incoherent equipment by setting specific type.
3. terminal type: differentiate that broadcast is signal source, decoder, precaution device or detector by setting specific type,
And whether corresponding operating is correctly executed according to operation result.
The function expression of Encryption Algorithm is as follows:
Y=f (x1,x2,x3)
Wherein independent variable x1, x2, x3Three user name, user password and MAC Address vectors are respectively corresponded, and dependent variable y is then
Corresponding broadcast vector.
When user name and user password vector determine, it is assumed that broadcast vector y should be obtained by real MAC address1；If at this time
There is the address MAC1 (being not aware that whether received MAC is true for anti-theft magnetic snap, it is therefore assumed that being different address MAC1) to exist
Broadcast vector y1, when anti-theft magnetic snap receives MAC1 vector 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 being to be unable to get correct broadcast only according to MAC Address under user name and user password vector unknown situation
Vector, 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 demonstrating, it is assumed that n > 6 (length of MAC).Therefore settable:
User name vector x1(being all binary system): 8n total:
A=(A01A02A03A04A05A06A07A08A11A12A13A14A15A16A17A18........An1An2An3An4An5An6An7An8)
Crypto vector x2(being all binary system): 8n total, the benefit 0 more than 8m:
B=(B01B02B03B04B05B06B07B08B11B12B13B14B15B16B17B18........00000000)
MAC vector x3(being all two progress): 8n total, the benefit 0 more than 48:
C=(C01C02C03C04C05C06C07C08C11C12C13C14C15C16C17C18........00000000)；
Operation result y1=f (x1,x2,x3)=f (A, B, C)=A*B*C=(A01A02A03A04A05A06A07A08*

In have calculated result spilling, then automatically interception most least-significant byte as the entry value；For convenience, tri- vectors of ABC can take same solid
Measured length facilitates the determination of broadcast length.
Verifying broadcasts process:
If the operation result that anti-theft magnetic snap is extracted from the signal received is y1, broadcasting corresponding terminal address is C1
(in order to distinguish C, being temporarily set as C1), then the result that anti-theft magnetic snap uses same algorithm to obtain by terminal address C1:
y2=f (x1,x2,x3)=f (A, B, C1)=A*B*C1=(A01A02A03A04A05A06A07A08*

If y1=y2, then it is true terminal；
If y1！=y2, then it is forgery terminal.
