Figure 1A shows the stream of the method realizing Electronic Signature according to one example embodiment of the present invention
Journey schematic diagram, Figure 1B shows the schematic diagram of the Electronic Signature according to one example embodiment of the present invention,
Fig. 1 C shows the schematic diagram of the digital certificate according to one example embodiment of the present invention；Can apply
On stamped signature server.As shown in Figure 1A, the method realizing Electronic Signature comprises the steps：
Step 101, determines the cryptographic Hash of the electronic document treating stamped signature；
Step 102, is encrypted using the private key corresponding with the public key in digital certificate to cryptographic Hash；
Step 103, the picture of cryptographic Hash, digital certificate and Electronic Signature after encryption is synthesized to electronics
In document.
In a step 101, in one embodiment, electronic document can be local file (for example it was demonstrated that
File, electronic receipt etc.)；In another embodiment, electronic document can come from the first business platform,
First business platform can be for paying type of financial business platform (for example, Alipay), accordingly, electronics
Document can prove for assets, bill, electronic receipt；In another embodiment, electronic document can come
From the second business platform, the second business platform can be deposit type of financial business platform (for example, wealth bringing in is precious),
Accordingly, electronic document can be loaning bill and interest proves；In another embodiment, electronic document is permissible
From the 3rd business platform, the 3rd business platform (for example, can net business for the Internet financial business platform
Bank), accordingly, electronic document can be electronic certificate of terminal use's application etc., it follows that
The application is not limited to the source of electronic document.
In one embodiment, Electronic Signature can be the corresponding enterprise of the first business platform Electronic Signature,
The Electronic Signature of the corresponding enterprise of the second business platform, the Electronic Signature of the corresponding enterprise of the 3rd business platform.
In one embodiment, the cryptographic Hash of electronic document can be extracted by Hash (Hash) algorithm.
In a step 102, in one embodiment, can be determined to cryptographic Hash according to the source of electronic document
Cipher mode, for example, if electronic document be derived from the first business platform, can be in stamped signature server
Setting encryption equipment, to be encrypted by first key (alternatively referred to as main key, MainKey) of encryption equipment
Private key in digital certificate；Again for example, if electronic document is derived from the second business platform, can be by the
Cryptographic Hash is sent to Third Party Authentication center (for example, CA center) by one dedicated network, by third party
Authentication center is encrypted by using the private key pair cryptographic Hash corresponding with the public key in digital certificate, it
Afterwards the cryptographic Hash after encrypting is returned to by stamped signature server by the first dedicated network；Again for example, if electric
Subdocument be derived from the 3rd business platform, can by cryptographic Hash, stamped signature server and third party's financial platform it
Between the second key of setting be sent to the encryption equipment of the 3rd business platform by the second dedicated network, by the 3rd
Business platform is encrypted using the second secret key pair cryptographic Hash that both sides set by encryption equipment, afterwards, the
Cryptographic Hash after encryption is returned to stamped signature server by three business platforms again.By the electronics to separate sources
Document is encrypted to cryptographic Hash using different cipher modes, can also meet the business demand of personalization.
In step 103, in one embodiment, can from corresponding business platform (the first business platform,
Second business platform, the 3rd business platform) obtain the picture of corresponding Electronic Signature, by the Kazakhstan after encryption
The synthesis mode that the picture of uncommon value, digital certificate and Electronic Signature is synthesized in electronic document may refer to existing
There is the associated description of technology, will not be described in detail herein.
As shown in Figure 1B, synthesis Electronic Signature on the electronic document is " AB company ", when listening to
During click event on the Electronic Signature of " AB company ", the correlation of the digital certificate shown in display Fig. 1 C
Information, because digital certificate is got by Third Party Authentication center, therefore can make user pass through
The true or false of digital certificate authentication Electronic Signature.
Seen from the above description, the embodiment of the present invention achieves the Internet stamped signature by step S101-S103
Pattern, solve the problems, such as that U-shield stamped signature scheme implementation cost of the prior art is high, reduce user
Cost, is synthesized to electronic document by cryptographic Hash encryption and by the cryptographic Hash after encryption and digital certificate
On, improve safety and the public credibility of Electronic Signature.
