Description
Technical field
The present invention relates to identity authorization systems, and in particular to a kind of Verification System based on vibration mirror scanning imaging belongs to peace
Full authentication techniques field.
Background technology
Based on physics unclonable function（PUF）Verification System there is extraordinary safety, recognize in next-generation safety
Have broad application prospects in card technology.Boris Skoric etc. propose QR-PUF on the basis of PUF, it is to utilize quantum
State reads PUF, and due to the nonclonability of quantum state, being authenticated using QR-PUF will be than traditional optical PUF key
With higher safety.S. A. Goorden etc. are devised on the working foundation of Boris Skoric based on speckle wavefront
The Verification System of detection, the system need to use two sets of entirely different light path systems in registration and certification, more complicated, limit
Its functionization is made.Therefore, designing a kind of can be carried out at the same time registration and the simple authentication system of certification is necessary.
Invention content
In order to overcome the problems, such as that existing quantum authentication system light path needs different registrations and certification light path, the present invention to devise
Based on the Verification System of vibration mirror scanning imaging, which irradiates optics PUF using higher-dimension quantum light and directly acquires speckle
The method and system that light intensity is authenticated, it is only necessary to which a light path can be realized as registration and two kinds of functions of certification.
Technical scheme is as follows：
Based on the Verification System of vibration mirror scanning imaging, include at least：Pulsed laser light source for sending out light pulse and along pulse
Attenuator group that laser light source direction of illumination is set gradually, beam expanding lens, Amici prism one, attenuator group are used for optical pulse energy
Decaying, beam expanding lens is for changing beam diameter, and Amici prism one is for being split light beam；By Amici prism one along direct projection
Light exit direction is provided with the spatial light modulator for being spatially encoded to light beam, goes out along refraction light by Amici prism one
It penetrates direction and is provided with Amici prism two, optics PUF keys are placed along direct light exit direction by Amici prism two, by light splitting
Prism two is provided with two-dimensional scanning mirrors along refraction light exit direction, and narrowband is set gradually on the light direction of two-dimensional scanning mirrors
Bandpass filter, photon counter, two-dimensional scanning mirrors and photon counter cooperation are for speckle scanning imagery, narrow-band bandpass
Optical filter is filtered ambient light used in photon counter inlet.
The two-dimensional scanning mirrors, photon counter are all connected with Control ＆ data acquisition module, Control ＆ data acquisition mould
The computer that block connection user uses.
Optical shutter is set on light beam exposure pathways between the beam expanding lens and Amici prism one.
It is provided with for light absorbing light shelves or ligh trap on the negative direction of the refraction light light extraction of the Amici prism one.
The Verification System includes registration and two implementation processes of certification when implementing.
When registration, identity marks first are carried out to optics PUF keys, process is：
First, the light pulse that pulsed laser light source is sent out is decayed, obtains weak coherent light light beam；The weak coherent light is by expanding
Shu Jinghou improves beam diameter and listened spatial light modulator to weak phase after Amici prism then by Amici prism one
Dry light is encoded；Light after coding is irradiated to optics PUF after Amici prism two and generates scattering light on the key, scatters light
Two-dimensional scanning mirrors are irradiated to by Amici prism two, are irradiated on photon counter after two-dimensional scanning mirrors；Use control
The movement of system and data acquisition module control two-dimensional scanning mirrors makes scattering light deflect, while using photon counter to not
Scattering light with deflection direction carries out photon counting, the count value of position signal and photon counter to two-dimensional scanning mirrors into
The operations such as row interpolation obtain the speckle pattern at photon counter.Coding mode due to changing spatial light modulator can obtain
Different speckle patterns, they are one-to-one, can form code-excited-response pair.Therefore, to optics PUF keys
Before being registered, optics PUF keys are irradiated using a kind of unification and fixed coding mode first, records and stores this fixation
Speckle under coding is corresponding, using it as the identity marks of this optics PUF keys；After completing identity marks record, change empty
Between optical modulator coding mode, record and store the excitation-response pair under different coding, these excitation-response pairs will recognized
It is spare when card, the registration to optics PUF keys is thereby realized, the PUF keys after registration can be distributed to user, user
Authentication is carried out using the PUF keys of distribution.
When user is authenticated using optics PUF keys, the load label optics PUF keys first in spatial light modulator
When the unified regular coding that uses, acquire speckle, judge whether optics PUF keys have by registering and distinguishing using the speckle
The not identity information of optics PUF keys；If there is no the speckle information in database, illustrate optics PUF keys without
Registration, cannot pass through authentication；If there is the speckle information in database, illustrate that optics PUF keys have passed through registration, so
It uses the excitation-response pair information of optics PUF keys to change the coding mode of spatial light modulator afterwards, acquires speckle pattern,
Whether consistent with the excitation-response pair of storage speckle is observed, if unanimously, authentication passes through, if it is inconsistent, identity
Authentification failure.
The number of photons of single pulse should be much smaller than spatial light in the weak coherent light obtained after the decaying of attenuator group
The pixel number of modulator.
The invention has the advantages that：
1. the present invention, which has used same set of system simultaneously, realizes registration and two kinds of functions of certification, light path is simple, easy to use.
2. the present invention acquires quantum speckle in such a way that photon counter cooperation galvanometer is scanned, improves quantum and dissipate
The collecting efficiency of spot, shortens acquisition time, facilitates and carries out fast registration and certification.
3. being filtered to ambient light using narrow band pass filter, influence of the ambient light to Verification System is reduced.
