In the specific implementation process, due to safety certification means common in the market have static password authentication, finger print identifying,
The modes such as iris authentication.Product on the market is simple RFID anti-counterfeiting system, is easily attacked, and data have the wind being stolen
Danger is based on the RFID authentication techniques domestic market blank of " chip finger print ".And the PUF skill that the present invention is added on this basis
The unclonable technology of art physics is utilized the random process deviation injected in chip manufacturing proces with processes such as illumination, generates core
Unique " fingerprint " information of piece can be used as the unique identification information of chip after special technique extracts.The unique identification is due to being
It is voluntarily generated in manufacturing process, designer, producer, the producer of chip can not control it, and ensure that anti-fake core
The physics of piece can not duplication characteristic.
Inherent physical structure based on physical entity realizes effective certification thinking uniquely to identify single physical entity,
Propose based on PUF(physics unclonable function) RFID certificate scheme, PUF has robustness, nonclonability and not
Predictability feature can be widely used in field of authentication.
This system has following innovative point: the innovation on protocol algorithm (software): protecting compared to other RFID privacies
Protect for algorithm, in the present invention the maximum advantage of RFID indentification protocol based on PUF that uses be without searching for database, i.e., without
It need to identify label, not search for difficulty, therefore the present invention can be used for large-scale RFID network.Our agreement theoretically may be used
All impersonation attacks are resisted, there is high safety.In addition, the agreement of our company's product is stateless protocol, label is not necessarily to
Synchronous with database holding, therefore, desynchronization attack is also invalid to this agreement.
Innovation on chip manufacturing (hardware): existing RFID chip safety is bad in the market, can easily be attacked
It is broken；If but additional encryption algorithm or circuit, cost, volume etc. can all increase.And PUF (Physical Unclonable
Function) the random process deviation injected in chip manufacturing proces with processes such as illumination is utilized in the unclonable technology of physics,
Unique " fingerprint " information for generating chip can be used as the unique identification information of chip after special technique extracts.The mark be
Spontaneous generation in manufacturing process, designer, producer, the producer of chip can not control it, ensure that anti-fake
The physics of chip can not duplication characteristic." fingerprint " information that PUF technology is extracted, is utilized physics generally existing in natural environment
There is preferable stochastic behaviour can produce random PUF KEY using the stochastic behaviour, combine with cryptographic algorithm for disturbance, can
It is obviously improved the attack tolerant energy and security level of cryptographic algorithm.
Innovation on chip memory capacity: nonvolatile memory applied by common RFID, the information of storage
Amount and required hardware number are linear, and therefore, the information content of its general storage is less, are not able to satisfy the informationization in epoch
Demand.But it is proposed that the information content that is stored of PUF and hardware number exponentially relation with increase.For example, to store
The information of 128bit needs nonvolatile memory 128.And for PUF, any 2 groups of ring oscillators can generate
1bit.Theoretically, N number of oscillator can generate log2 (N!) a independent bit.Meanwhile we will be using phase inverter multiplexing
Method increases the quantity of oscillator on unit area, so that information storage volume be made to reach maximization.
(farther distance of reaction, lower cost price are wider to be more easily applicable in for improvement in terms of life practicability
Range): the present invention optimizes conventional ultra high frequency RFID transmission circuit, improves reader receiving sensitivity, stablizes and reads
Distance reaches 25m, improves about 20%-30% than common ultrahigh frequency RFID reader on the market.In research and development using special filtering
Device and isolated from power design, enable other electronic equipments to be preferably minimized the interference of instrument so that ultrahigh frequency readers obtain it is super
The identification and communication sensitivity of similar products at home and abroad are crossed, the reading under equal-wattage is apart from further expansion.
RFID technique based on PUF mainly reduces cost at two aspects, and one is reduction of the requirement of external environment, second is that
Reduce small product size.
Information is stored in nonvolatile memory by common RFID, such as EEPROM/Flash ROM.These memories
Production needs additional process.Their write-in environmental requirement is harsh, for example needs high voltage, ultraviolet light irradiation etc., and PUF institute
Component mostly uses greatly CMOS technology, it is only necessary to which normal voltage, external environment require to substantially reduce.In addition, this production
Product have used completely new Technical Architecture.Traditional software and hardware product is all the module splicing exploitation ready-made using market, Hen Duomo
Miscellaneous function in block not using and waste.In research and development using the customized type technology frame closer to actual user's demand
Structure abandons all unwanted parts, maximizes and reduces small product size, and save the cost reaches the two-win of performance and profit.
The RFID Verification System for chip finger print of the high encryption mainly prevents chip information from copying and preventing
The big function of product counterfeiting two.
Prevent information copy: existing RFID is that identification information or code key are stored in non-volatile type memorizer, example
Such as EPROM, FLASH ROM.But hacker easily can be stored in the ID in non-volatile type memorizer by physics extraction RFID
Information, and copy to inside another RFID label tag.RFID and original RFID after duplication are not different.Simultaneously because RFID
Label need not be contacted directly with transceiver, and user can read the information that tag memory stores up, structure by other people without knowing it
At hidden trouble in safety.
If the RFID of additional encryption function is designed, although can be improved the safety of label, label and read-write equipment
Cost and internal complicated agreement will improve cost, greatly limit the application range of label.
And PUF technology just seems " fingerprint " of chip, using the variation in the physical characteristic and IC manufacturing process of silicon come only
The one each chip of mark.Because the variation of IC manufacturing process can not mathematically establish model, it is can not to answer
It makes or controls." clone " chip and original chip necessarily have the difference in structure, then when input stimulus, the phase of generation
The ID answered is centainly different, and then effectively prevents the clone's problem and information stealth problem of RFID.
Prevent product counterfeiting: by " fingerprint " chip in the embedded present invention of each product, when client user obtains product
Afterwards, it uses handheld device (mobile phone or computer) as reader, opens corresponding App and chip id is read out, after then authenticating
Platform can match ID data with the data in our database.If successful match, then it is assumed that chip is effective, and product is true.
The core of the RFID Verification System for chip finger print of high encryption is chip body in the present invention, and one piece complete
RFID chip is by RFID label tag, RFID reader, RFID antenna three parts composition.
RFID label tag: the RFID label tag in the present invention is otherwise known as electronic tag, can be attached to the surface of purpose object,
Such as the bar code in supermarket, it can also independently place, such as in the ETC card used on highway.
Label both can receive signal, and signal can also be issued to reader, these signals include a unique ID, with
And it is stored in the data (such as inventory number, article No., date of manufacture etc.) in reservoir before.It shows in the present invention, is one
The corresponding ID uniquely determined of product, stores in reservoir in the present invention.
System in the present invention uses passive type electronic tag, internal not have power supply power supply, by the electromagnetism received
Wave is driven (radio energy of reader transmission).
The operating mode of RFID can be it is read-only, can also be with read/write.Based on this characteristic, can be persistently written with the later period
Algorithm upgrades product.
RFID is by an integrated circuit, an antenna and a reservoir.Integrated circuit is for storing and processing information tune
System, while demodulating radio frequency (RF) signal.Namely one is used to adjustment signal and extracts the circuit of signal；It
Line is then for receiving and sending signal；Reservoir is for storing internal information.
RFID reader: RFID reader utilizes Radio Frequency Identification Technology, is read out to FRID label information, typical raw
Reader that we use in work such as Pos machine etc..
RFID reader is to carry out inquiry to RFID label tag by sending the radio signal of a string encoding.When RFID is marked
Label receive radio signal, can be responded with its sequence number (ID) and other information.Since each label has individually
Sequence number (ID), RFID system can distinguish different labels, and multiple labels are incuded within the scope of RFID reader
And them are read simultaneously.That is, can be scanned again with a mobile phone to multiple labels in this system, commodity are completed
Visit pseudo- and certification.
The identification range of RFID reader is also very wide, farthest up to 1500 meters.Its inside uses unique operation method
It is then identified with intermediate frequency, enhances the anti-interference of machine, even if guaranteeing reader in high-intensitive noisy environment and High-frequency Interference
Under, it can also complete to identify.It, not only can be with the peace of guarantor and testee using RFID when the occasion in some bad environments
Full distance, while the completeness identified can also be guaranteed, this is the advantage place of RFID identification.
RFID reader is divided into fixed and hand-held, using mobile phone as a kind of reader of hand-held in the present invention,
It is provided a great convenience for user, improves the portability of whole system.
RFID antenna: RFID antenna is the transponder of electronic tag, and transmitting radio frequency letter is played between label and reader
Number effect, be of great significance to RFID identification system.
RFID system antenna can be divided into traditional thread binding antenna and planar antenna two major classes according to shape.If passing through material and system
Technique is made to classify, metal etch antenna, printed antenna, copper facing antenna etc. can also be divided into.The shape of label antenna, antenna
Impedance, the RF characteristic being applied on article are all an important factor for having an impact to RFID system.
Antenna is usually passive device, it can't amplify electromagnetic signal.The gain of so-called antenna is the electricity for radiating it
After magnetic wave carries out pack, compared with ideal reference antenna, receive the ratio of power under conditions of identical input power.And it is high
It is cost that gain, which is by the poly- range of penetrating for reducing antenna beam,.
Therefore, the present invention is based on the RFID systems of PUF design to have the advantage that
(1) structure is simple, at low cost, and private information is stored in nonvolatile memory by common RFID, such as EEPROM/
Flash ROM.The production of these memories needs additional process.Their write-in environmental requirement is harsh, for example needs high electricity
Pressure, ultraviolet light irradiation etc..And component used in PUF production process is all the CMOS technology of standard；Applied voltage is all standard
Voltage.
(2) storage information capacity is big, nonvolatile memory applied by common RFID, the information content of storage and institute
The hardware number needed is linear.But the information content that is stored of PUF and hardware number exponentially relation with increase.
(3) highly-safe, basic RFID does not have safety, and PUF utilizes the physical characteristic and IC manufacturing process of silicon
In variation, carry out each silicon chip of unique identification.Because the variation of the manufacturing process of IC is mathematically that impossible establish mould
Type, at the same be also can not replicate or control, PUF not only can be with identification chip, but also itself is also unclonable.It utilizes
Intrinsic variation in IC manufacturing process, PUF provide a safety, robust, and cheap mechanism carrys out the silicon chip for verifying.
Therefore, market will have the application prospect become better and better to the RFID authentication techniques based on " chip finger print " at home.
Different authentication modes respectively has thousand on the market, and authentication mode of the invention has the following advantages that.
Cost: for cost, static password authentication is the cheapest, can depend on equipment itself.Fingerprint and iris are recognized
Demonstrate,prove more demanding to authenticating device, need accurate algorithm, while being also required to the acquisition of data early period, manpower and material resources consumption compared with
Greatly, cost is also corresponding higher.And we release based on PUF, depend on RFID chip itself, cost is relatively low, is also not required to very important person
To input a large amount of user information, spending is saved, cost is saved.
Applicability: static password needs user to directly input password, lower to environmental requirement, but recognizing in this way
Card has often required that the equipment such as keyboard, screen, volume are larger, it is difficult to which completion depends on requirement to product.Have one with password authentication
The problem of sample, iris recognition are also difficult to minimize image acquisition equipment, poor to the dependency of product, while iris equipment pair
Required distance is higher, and general to require in 20-40cm, the interactivity of user is bad, in certain occasions and is not suitable for.Fingerprint input exists
Also there is limitation in applicability.According to authentic data, about 5% user is difficult to realize finger print identifying, among these includes holding
It easily perspires, the user that finger lines is shallower, further includes some on hand with attachment, such as user of hard cocoon or dirt.As for
The practicability of the technology of public service, fingerprint recognition is obviously limited.For RFID, its applicability is extremely strong.Chip it is small in size,
Mobility is good, can depend on product surface.Meanwhile RFID technique is all lower to user and external demand, in a variety of environment
All there is good applicability.
Safety: static password authentication content, which is easily stolen, to be peeped or is inferred, and safety is poor.Simple password is easy
It is broken, and complicated password user is not easy to remember, practicability is not high.Although fingerprint recognition is using the uniqueness of fingerprint as technology
Basis, but fingerprint has the possibility for being replicated, stealing, and safety is also inadequate.Secure authentication technology PUF novel as one kind,
Safety is high, and the KEY ID of generation has randomness and uniqueness, it is difficult to be replicated, attack tolerant energy and safety all belong to peace
Full technical field front end.
Performance indicator comparison: since the basic blank of application field, the system are realizing security information pair to the technology at home
When than function, internet is uploaded by server and carries out information exchange, strong antijamming capability, and " chip finger print " on RFID
It is easy to client's carrying, can satisfy the demand of different levels user's different directions.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
