Description
Technical field
The present invention relates to seals, especially a kind of to synchronize to the synchronous progress CA certificate label of the body of an instrument or photo of signing
The intelligent seal of word.
Background technique
During legal relation occurs with the external world, seal plays the work for representing personal or unit will in form
With.No matter daily contacts or law court assert that the effect of relevant document is true in turn in the censorship of dispute, foundation is affixed one's seal
Fixed jural ownership has become a common sense.Enterprise's seal represents enterprise's whole or the will in terms of certain, no
It is proper use of that huge loss may be brought to enterprise.E-seal technology is with simulation with digital technique transmission seal material object print
Chapter, management and usage mode meet the habit of seal in kind, and the electronic document covered has as traditional chapter in kind
Appearance and the same validity.In order to increase the safety of E-seal, also to sign electronically to electronic seal data,
There are many kinds of the methods for realizing electronic signature, current e-commerce, the application of E-Government kind is most universal, technology is most mature,
The strongest electric endorsement method of operability is exactly " digital signature ".Asymmetric encryption techniques are a kind of currently used number label
Name method, that is, use PKI (abbreviation of PublicKeyInfrastructure, referred to as Public Key Infrastructure) system, and counts
Word certificate is exactly a kind of key management medium of PKI system.It is the electronic document of authority a kind of, just as one in network environment
Kind identity card, for proving the identity of some main body (such as people, server etc.) and the legitimacy of its public-key cryptography, also known as
Digital ID.Digital certificate by a pair of secret keys and user information and third party's digital certification authority (CertificateAuthority,
Hereinafter referred to as CA) the data such as digital signature collectively constitute, and be written in certain storage medium, it is ensured that user information is not non-
Method reads and distorts.Digital certificate (digital certificates) is usually the third party's digital certification authority (i.e. CA) trusted jointly by everybody
It issues.Any one trusts one side of communication of CA, can be set up by the CA signature on verifying other side's digital certificate
With the trust of other side, and obtain other side public key in case use.However above-mentioned digital certificate, it is all using one when in use
It is realized as the USBKEY of USB flash disk, such product when in use can be inconvenient.
