Description
Technical field
The present invention is related with a kind of truly random password generation device, especially a kind of truly random password optics of down-sampling multidigit
Generation device is suitable for the fields such as cryptography, information security.
Background technique
Information network security is directly related to numerous aspects such as national security, trade secret, individual privacy.The U.S. in 2013
The exposure of " prism plan ", other country's vital strategic secrets can be stolen by communication network technology by having exposed；Meanwhile it is each also to expose the world
Technology short slab of the state in terms of safety information product.
Password is the last barrier to ensure information safety.It is raw to generally use the pseudorandom cipher based on algorithm in the world at present
At technology, high speed pseudorandom cipher equipment is manufactured.But as its name, it be it is pseudorandom, not can guarantee being perfectly safe for communication,
It is the root that extensive password takes place frequently according to leakage event in recent years.It is different from pseudo random techniques, using physical accidental process as
Entropy source can produce the truly random password that can not be cracked, and fundamentally prevent the generation of information leakage event.However, it is existing very with
Secret code product mainly extracts truly random password from thermal noise, oscillator jitter etc., is limited to entropy source bandwidth bottleneck, code rate
In Mb/s magnitude, it is unable to satisfy the requirement of present information high-speed transfer.
Chaotic laser light signal is with substantially random fluctuation characteristic, bandwidth may be up to GHz magnitude.Use laser chaos for physics

The weight for the ultrashort light pulse sequence that finally code rate of obtained truly random keying sequence is exported by Mode-locked laser device 1
Complex frequencyfIt determines and whole digits 64 of 64 analog-digital converters 9 determines, be equal to 640 Gb/s=64 × 10 Gb/s.Attached drawing 5
It is the two-dimentional point diagram of the real-time truly random keying sequence of the high speed.By attached drawing as it can be seen that generated truly random keying sequence 0,1 is distributed
Uniformly and be free of any periodicity.
In order to examine the random quality of truly random password caused by the present invention, inventor uses American National Standard and skill
Art research institute (NIST) provide 800-22 random cipher testing standard of Special Publication to it is generated with
Machine keying sequence is tested.NIST random cipher testing standard is general international standard, is tested altogether comprising 15, each
Test result is usedPValue indicates.IfPValue is greater than level of signifiance valueαWhen=0.01, then show that surveyed random cipher sequence passes through
Corresponding test.Further, the percent of pass of each test is calculated further to verify the validity and just of sequence stochastic behaviour
True property.When the percent of pass of each test is greater thanWhen, it is believed that surveyed random cipher has good randomness.This
In,p = 1- α。
Specifically, the real random code sequence that inventor acquires that 1000 pool-sizes are 1 Mbit respectively carries out NIST survey
Examination.At this moment, it is desirable that the percent of pass of each test is greater than 0. 9806.The test result of inventor shows each caused by the present invention
The truly random password of full light under kind rate all has the stochastic behaviour of high quality, can all successfully pass NIST random cipher test mark
It is quasi-.Subordinate list 1 gives the worst test result that NIST test is carried out to truly random password produced by the present invention, but each
Item testPValue is still all larger than 0.01, and items test percent of pass is all larger than 0.9806, has reached random cipher testing standard, has demonstrate,proved
The real random code randomness that the bright present invention generates is good.
It can see by discussed above, the truly random password optics generation device of a kind of down-sampling multidigit of the invention is entire
It in signal processing, does not need electric clock and participates in, to effectively prevent electronics ADC rate limit caused by being shaken by electronic clock
Problem.Specifically, the present invention using all-optical switch using ultralow shake ultrashort light pulse in full area of light to chaotic signal into
The ultralow shake sampling of row, using the parallel output type multi-bit ADC clock-driven, without sample-hold circuit without electricity to mixed
Ignorant pulse carries out quantification treatment, generates the real random code sequence of hundred Gb/s magnitudes, the code rate of the prior art is improved at least two
A order of magnitude.
In addition, it is necessary to which it is emphasized that the code rate of truly random password caused by the present invention is by Mode-locked laser device
Repetition rate and multi-bit ADC whole number of significant digit determine.Real random code generator of the invention is due to using self-dalay
Quantification technique, so that whole significance bits can be retained in quantizing process, the direct truly random password of outputting high quality, without existing similar
Many and diverse subsequent processes necessary to technology and the technological deficiency for abandoning most significant bit (MSB), effectively prevent subsequent place
Synchronization challenges during reason between high-speed electronic component.
