Step 2, Bluetooth encryption, concretely comprise the following steps:
Step 2.1, the storing path of file after the load path of stamped signature file to be encrypted and encryption is set by mobile client, utilize the user encryption CertPubKey in bluetooth KEY that the stamped signature file selected under load path is encrypted, and the cryptographic signature file after encryption is stored to storing path；
Step 2.2, is selected the cryptographic signature file under storing path by mobile client, and is one ID numbering of this cryptographic signature document creation, then this cryptographic signature file and ID numbering thereof are uploaded to Electronic Signature server；
Step 3, bluetooth deciphering, concretely comprise the following steps:
Step 3.1, is nearby searched matched bluetooth KEY by mobile client, and sets up bluetooth with bluetooth KEY of coupling and be connected；
Step 3.2, the ID numbering of cryptographic signature file to be decrypted is inputted in mobile client, downloaded or from the cryptographic signature file of this locality loading coupling from Electronic Signature server according to the ID numbering of input by mobile client, and utilize the user encryption certificate private key in bluetooth KEY that the cryptographic signature file of coupling is decrypted, if successful decryption, then to user feedback successful decryption information, if deciphering unsuccessfully, then decipher failure information to user feedback.
Use bluetooth KEY and mobile client carry out with the use of, make user just can be realized the making of Electronic Signature by portable mobile client, and without carrying with PC, be effectively increased the convenience of Electronic Signature；Bluetooth KEY is used to carry out encryption and decryption, it is possible to effectively to enhance the safety of Electronic Signature encryption and decryption；Use ID numbering can search the encryption file of coupling conveniently and efficiently, effectively enhance the efficiency of Electronic Signature.
As the scheme that limits further of the present invention, bluetooth KEY is provided with user certificate, user certificate be use administrator's password key sign in the application of third party's ca authentication center by after be stored in bluetooth KEY, for applicant is carried out identity verification.Use and user certificate is set in bluetooth KEY, it is possible to for applicant is carried out identity verification, further enhancing the safety of Electronic Signature encryption and decryption.
The beneficial effects of the present invention is: (1) use bluetooth KEY and mobile client carry out with the use of, make user just can be realized the making of Electronic Signature by portable mobile client, and without carrying with PC, it is effectively increased the convenience of Electronic Signature；(2) bluetooth KEY is used to carry out encryption and decryption, it is possible to effectively to enhance the safety of Electronic Signature encryption and decryption；(3) use ID numbering can search the encryption file of coupling conveniently and efficiently, effectively enhance the efficiency of Electronic Signature.

Detailed description of the invention
As it is shown in figure 1, this kind of based on the wireless encryption and decryption of bluetooth electronic signature method, comprise the steps:
Step 1, Electronic Signature makes, concretely comprises the following steps:
Step 1.1, is sent the solicited message of Electronic Signature application, and identity information and the documentation of identity of applicant is uploaded to Electronic Signature server simultaneously by signature client to Electronic Signature server；
Step 1.2, according to identity information and the documentation of identity of applicant, applicant is carried out identity verification by Electronic Signature server, if identity verification is correct, then administrator's password key and bluetooth KEY are connected to Electronic Signature server, and carried out Electronic Signature making by Electronic Signature server according to the user's stamped signature in bluetooth KEY, final acquisition stamped signature file, if identity verification mistake, then feeds back identity verification error message to signature client；
Step 2, Bluetooth encryption, concretely comprise the following steps:
Step 2.1, the storing path of file after the load path of stamped signature file to be encrypted and encryption is set by mobile client, utilize the user encryption CertPubKey in bluetooth KEY that the stamped signature file selected under load path is encrypted, and the cryptographic signature file after encryption is stored to storing path；
Step 2.2, is selected the cryptographic signature file under storing path by mobile client, and is one ID numbering of this cryptographic signature document creation, then this cryptographic signature file and ID numbering thereof are uploaded to Electronic Signature server；
Step 3, bluetooth deciphering, concretely comprise the following steps:
Step 3.1, is nearby searched matched bluetooth KEY by mobile client, and sets up bluetooth with bluetooth KEY of coupling and be connected；
