Description
Technical field
This disclosure relates to which a kind of method and system and servomechanism of guard digit stamped signature mechanism, especially a kind of using random
The method and system and servomechanism of the guard digit stamped signature mechanism of code.
Background technique
In the program of some numerical digit stamped signatures (Digital Signature, DS), transmission end calculates information by hash
Method obtains a Hash Value (hash value) after calculating, and the private key of transmission end is recycled to become a numerical digit to Hash Value encryption
Stamped signature.Then, then numerical digit stamped signature is attached to behind information and is sent out together.After receiving end receives information, transmission is utilized
The public key at end decrypts numerical digit stamped signature to obtain the Hash Value of transmission end, due to confirmed the pairing relationship of public key and private key, and energy
Determine received information " non-repudiation ".Then, receiving end calculates Hash Value with the calculation of same hash, and compares
Two Hash Values can determine " integrality " of the information if identical.

In example, random code inventory L4It is received from the random code generation device 1, and includes one or more random codes being randomly generated
R4, in the present embodiment, random code inventory L4It is uniquely corresponding to the client and is identical to random code inventory L2.The random code
R4A part be not labeled, the random code R4Another part be labeled.In the present embodiment, random code R4It is labeled
Mode can be and be marked as having used.In the present embodiment, the second part P of numerical digit private key data4And the numerical digit private key
The first part P of data2A private key for being uniquely corresponding to the client can be collectively constituted, in other words, the of numerical digit private key data
Two part P4It can be the first part P for being different from the numerical digit private key data for the private key for being uniquely corresponding to the client2It is another
Part.
In the present embodiment, the first part P of the numerical digit private key data2It can be and the client is sent to by the servomechanism 2
End device 4.In other embodiments, client dress can be sent to by other electronic devices for being different from the servomechanism 2
4 are set, such as belongs to third-party electronic device.
43 data connection of the processing unit communication module 41 and the storage unit 42.The processing unit 43 may include fortune
Calculate module 431 and stamped signature module 432.The computing module 431 and stamped signature module 432 respectively may include one or more hardwares,
The electronic module of software or firmware.The computing module 431 and stamped signature module 432 can be the same hardware.
The computing module 431 of the processing unit 43 assembles to be stored in not marked for the storage unit 42 determining
It is denoted as used random code R2Quantity less than a predetermined value when, transmission one random code request to the random code generation device 1,
And it receives from the random code generation device 1 by the communication module 41 in response to should be with caused by random code request
When machine code inventory, store the random code inventory, will before receiving the random code inventory stored random code (such as random code
R4) be labeled as having used.
The computing module 431 of the processing unit 43 also assembles to transmit a stamped signature by the communication module 41 and request to this
Servomechanism 2.The computing module 431 of the processing unit 43 also assembles to receive by the communication module 41 from the servo
When the stamped signature of device 2 is replied, according to the coding, random code R used in the servomechanism 2 is calculated2, the numerical digit of the encryption it is private
The second part P of key data2, the coding generation time and the Hash Value, and the random code R according to used in the servomechanism 22、
The second part P of the numerical digit private key data of the encryption2, the coding generation time calculate one with reference to Hash Value.
The computing module 431 of the processing unit 43 also assembles determining the random code used in the servomechanism 2
R2Be matched be stored in the storage unit 42 be not labeled as used random code R4One of them, and determine the reference
Hash Value is identical to the Hash Value, and when determining current time within an effective time according to the coding generation time, utilizes
Random code R used in the servomechanism 22To the second part P of the numerical digit private key data2Decryption.The stamped signature of the processing unit 43
Module 432 and second part P according to the numerical digit private key data2With the first part P of the numerical digit private key data4Generate a private key
To carry out numerical digit stamped signature to a target data.The time interval that effective time can calculate backward for coding generation time, can also
To be the period of designated date.For example, in a situation, coding generation time is 3 days 15: 30 April in 2019
Point, effective time be on the same day 15 points 40 minutes, in this case, effective time be encode generation time calculate backward 10
Minute.
It is worth noting that by determining that this is identical to the Hash Value with reference to Hash Value, can be confirmed coding generation time,
Random code R used in the servomechanism 21And the second part P of the numerical digit private key data of the encryption1It is complete and is not altered
Change.By the timeliness for confirming that the current time can ensure that data within an effective time.
In the present embodiment, the computing module 431 of the processing unit 43 also assembles to be made determining the servomechanism 2
Random code R2Be matched be stored in the storage unit 42 be not labeled as used random code R4When, it will be stored in
The matched random code R of the storage unit 424Labeled as having used.
It is worth noting that through by used random code R2And random code R4Labeled as having used, once it is previously used
Random code R2It outflows and is comprised in the stamped signature emitted by puppet a reply, which is receiving the pseudo- label emitted
When Zhang Huifu, numerical digit stamped signature can not be also executed, in this way, can lifting system safety.
It is worth noting that in the present embodiment servomechanism 2 using be stored in the servomechanism 2 random code inventory L2 and
Not labeled random code R2It is to use in order, and the client terminal device 4 is also to compare to be stored in order when one of them
The not labeled random code R of the storage unit 424It is to be matched with the random code used in the servomechanism 2 with the presence or absence of one
R2, and all random code R of entire random code inventory L4 need not be compared4, in this way, calculation resources can be saved effectively.Other real
It applies in aspect, servomechanism 2 is using the random code inventory L2 for being stored in the servomechanism 2 and labeled random code R2Wherein one
When person, it can be and randomly use.
In other state sample implementations, stamped signature reply can be stored in the servomechanism 2 according to used in the servomechanism 2
And it is not labeled as used random code R2The second part P of one of them and numerical digit private key data1It generates.The then processing
The computing module 431 of unit 43 is being sentenced when receiving the stamped signature reply from the servomechanism 2 by the communication module 41
Make random code R used in the servomechanism 22Be matched be stored in the storage unit 42 be not labeled as it is used with
Machine code R4It, can be directly according to the second part P of the numerical digit private key data when one of them2With the number for being stored in the storage device 42
