Specific embodiment
Apply the present invention to during tourist group points out, tourist group's automatic roll-calling system (R-AUCA system) based on RFID from
Dynamic to find out whether each member of tourist group is on the scene, tour guide no longer needs oral roll-call, and roll-call need to be only looked over when needing to call the roll
Device can.
R-AUCA system is made of RFID member's card and hand-held roll-call device, as shown in Figure 1.
Active RFID tag is packaged in RFID member's card, the identity ID storage of each member is in the label.In member's card
Control module execute system protocol in certification response.It is recommended that setting 10 meters to 20 for the operating distance of active RFID tag
The range of rice.
Hand-held roll-call device includes three RFID module, management module and man-machine interface modules.RFID module is in management mould
It being communicated under the control of block with RFID tag, management module executes certification initiation and authentication result judgement in system protocol,
Man-machine interface supports human-computer interaction.Management module completes the poll to all members within each roll-call period, and certification passes through view
For call the roll successfully (on the scene), failure (absence) of otherwise calling the roll；Counted after roll-call end cycle number on the scene and absent number and
It is shown in man-machine interface, if absent number is not 0, warning reminding tour guide pays attention to.
The mode of alarm can be sent directly to show in man-machine interface, can also increase by one in hand-held roll-call device and report
Alert module realizes the function of reminding tour guide by driving alarm mode in the form of sound, light or vibration.
In tourism is called the roll, everyone is packaged with the card of RFID tag with one, is stored with person identifier in label
Information.Because personnel's distribution is at several meters to more than ten meters in tourism, only active RFID is just able to satisfy its requirement of calling the roll.When certain
People is then " on the scene " in tour guide's active RFID sphere of action, is otherwise " absence " (far from tourist group).
System protocol is that the certification that hand-held roll-call device blocks RFID member is as follows:
In R-AUCA system, member's card and roll-call device shared key K.System is realized using cryptographic algorithm 3DES or AES
Two-way authentication, Encryption Algorithm are EK (), and decipherment algorithm is DK ().
A. system initialization specifically includes:
A1. membership table is pre-established in roll-call device, each single item of table is containing 4 fields: member's serial number, member name, at
Member card ID, member condition.Member condition is predisposed to sky.Membership table is mapped to man-machine interface.
A2. three parameters: total number of persons, number on the scene, absent number are arranged in roll-call device.It is total that " total number of persons " is predisposed to tourist group
Number, " number on the scene " and " absent number " are predisposed to 0.Parameter is mapped to man-machine interface.
A3. roll-call device carries out cycle polling roll-call to member using time T as the period.Cycle T can be selected between 5~60 seconds
It selects.
B. the poll roll-call algorithm in a cycle: roll-call device is called the roll by membership table from first to last one one by one.
It is as follows to the roll-call program of ith member:
B1. roll-call device takes the member identification code ID from membership tablei, a random number r is generated, C=EK (r ‖ ID is calculatedi),
Send C.‖ is string-concatenation symbol.
B2. all members, which are clamped, receives C.
B3. each member's calorimeter calculates D=DK (C), and ID is extracted from D；If ID is not equal to the ID of oneself, abandon；
If ID is equal to the ID of oneself, roll-call response message A=EK (r ‖ ID ‖ " I am here ") is calculated, A is sent to roll-call device.
B4. roll-call device receives and calculates B=DK (A) after A, and r and ID is extracted from B, if r is effectively and ID=IDi, then connect
By being completed to the roll-call of ith member, setting the member condition is " on the scene ", updates the man-machine interface member condition.If r without
Effect or ID ≠ IDi, then abandon.
B5. i+1 member call the roll the moment arrive when roll-call device receive ith member not yet and call the roll response, then i-th
The roll-call of a member fails, and setting the member condition is " absence ", updates the man-machine interface member condition.
C. after a roll-call end cycle, roll-call device counts calculating parameter " number on the scene " and " absent number ", more new person
The machine interface two parameter.If absent number is not equal to 0, signal an alert.
Realize that the automatic roll-calling in tourism can mitigate the working strength of tour guide significantly using RFID.R-AUCA system is real
When system, the whereabouts of each tourist group member can be tracked at any time, the discovery of system one has member's " absence " (to exceed active RFID
Operating distance) it alarms immediately, prevent member to wander away accident.Information security be it is extremely important, in order to prevent to roll-call
Interference and Replay Attack realize certification of the roll-call device to RFID tag using computer cryptography technology, guarantee the safety called the roll.
