Abstract
The present invention relates to a safe electronic mail system with booked mail characteristics, user can used said system pattern to trace the state of document delivered by means of system to make mail and document possess safety, security, completeness and non-denying property. Said invention uses public very mechanism on the mail server to make document undergo the processes of encryption, signature and digital postmark treatment, at the same time it can provide third party proof function.
Description
The present invention relates to the secure email transmissions system.
What present e-mail system was used is that the digital certificate mode is carried out, encrypted and signs, wherein the document of Chuan Songing also is the form that converts Email to, part as Email is handled, transmission speed is slow, the recipient can deny receiving, two be end-to-end alternately, do not have third-party notarization function, limit for above-mentioned reasons, using in the high place of security requirement has a lot of weak points.
Task of the present invention provides a kind of safe, effective, simple safety E-mail, document transmission system.And have third party notarization and a undeniable sexual function.
The purpose that the present invention reaches is achieved in that after server is received the document that the sender uploads server uses the private key key of oneself to sign to it, produces digital postmark.Send the email notification recipient of envelope notice usefulness then.Document is removed to download to server in address on recipient's Email as per advice.After downloading, the time of recipient's identifying file and integrality.Guarantee correct, the effective and safety of document.After the recipient downloaded, server sent an envelope receipt and notifies the sender with Email, the designated user's download of document.The document that sends can the person of being sent out uses recipient's public-key cryptographic keys and the private key key of oneself is encrypted, signature operation.
The present invention writes and understands that set of systems becomes execution pattern, data flow.Can be easy to realize, can in present ecommerce, E-Government, enterprise's office etc., be applied.The present invention is in the enterprising line number signature operations of server and send notification of document and receipt document, clear in structure, advantages of simple.Do not influence user's operation.The use public key technique is carried out strong protection support to integrality, fail safe, the non-repudiation of document.Use pattern in real system is:
1. the sender downloads electronic post office's certificate (PKI) and addressee's certificate (PKI).
2. the sender reads the file that will send, and produces expressly.
3. the sender signs to plaintext with the private key of oneself
4. the plain text encryption after the sender will sign with recipient's PKI.
5. ciphertext is uploaded to the electronic post office that registers.
6. the response piece mailpiece of electronic post office's hair band numeral postmark is given the sender, and documentary evidence passes
To electronic post office.
7. sign to transmitting time with the private key of oneself in the post office, is file and adds a cover ELECTRONIC POSTMARK.
8. mail is sent out public notice to the recipient in the post office.
9. the recipient lands the post office and fills in and receives receipt (using private key signature).
10. the recipient downloads ciphertext.
11. the sender is notified in the post office, the addressee has received file.
12. the recipient uses the public key verifications numeral postmark of post office.
13. the recipient uses the private key of oneself to file decryption.
14. the recipient signs with sender's public key verifications.Native system adopts open technical standard; adopt digital certificate that the user is carried out authentication; guarantee the legitimacy of user identity and the authenticity of information transmitter identity, the electronic mail and the document that adopt Digital Envelope Technology to protect the user to send are not stolen or are distorted by other people.Provide the ELECTRONIC POSTMARK service that the delivery time of document is carried out safeguard protection.The notarization of the file that is provided by reliable third party is provided.The numeral response piece services has guaranteed electronic mail and document accuracy and the reliability in transport process.Take secure communication protocols to finish the foundation of secured communication channel.System adopts powerful mail server to provide standard, mail and document transmitting-receiving service reliably, multiple transmitting-receiving modes such as the transmitting-receiving of support standard, WEB transmitting-receiving for the user.
Claims (1)
- A kind of new type of safe e-mail system transceiver mode, it is characterized in that: the sender signs, encrypts document, is sent to server, and server uses private key to sign to it and produces digital postmark, and the send Email notification receiver receives.Recipient's logon server is downloaded protected electronic document, behind the certifying signature, and deciphering.After the download, the server send Email notifies sender's document to be received.
