Abstract

The invention provides an electronic signature for an endorsement of an external safety component on an electronic component, comprising a safety component and a electronic signature body; wherein the safety component obtains cipher-text information through carrying out an encrypted operation on signature information by an encrypted operation module taking private key information of an endorser and public key information of an endorsee as a password and sends the cipher-text information to an information processing component through an interface component, and the information processing component converts the cipher-text into signature data written by a read-write module to the electronic component. By adopting the technology, the uniqueness and the non-imitability of the signature information are improved and electronic bills are safer to be used. Because the invention realizes effective signatures of the electronic bills by adopting an easy identification and use method, risks of using the electronic bills are remarkably reduced, and the development of modern financial industry is promoted.

Description

External safety component is to the Electronic Signature of electronic unit endorsement signature

Technical field

The present invention relates to the Electronic Signature of external safety component, particularly relate to the Electronic Signature that passes to the external safety component that the electronic unit that is embedded in the medium such as radio electronic label be used for bill identification after the endorsement signing messages encrypted electronic unit endorsement signature.

Background technology

Along with the development of modern economy, the health of financial circles, orderly, safe development are significant for current economic development.In the financial circles development, popularize to the comprehensive of various financial documents gradually from money transaction, become the main means of payment that miscellaneous service is carried out in the modern economy like the letter of credit, cashier's cheque, check etc.

But because the value of financial document itself and circulation receive very big challenge for the security of financial document.Report is arranged when forging case that the letter of credit, cashier's cheque, check carry out financial swindling all over the world.And owing to the circulation of the letter of credit, cashier's cheque, check can repeatedly be transferred the possession of, and wherein any once transfer appearance forgery all possibly bring massive losses to the related side.

With regard to the antifalsification of the present employed letter of credit, cashier's cheque, check normally based on some anti-false signs on concession manufacturing and the ticket; The validation of the letter of credit, cashier's cheque, check is based on the person's that provides the bill signature or endorsement.And based on the reason of cost with technology, the anti-false sign of the letter of credit, cashier's cheque, check is also uncomplicated, is easy to by the fake producer imitated.And there are two problems in the signature or the endorsement that are used for the validation of the letter of credit, cashier's cheque, check: be that signature or the endorsement that same individual carries out in decentraction situation attitude, different time points can not guarantee in full accord on the one hand; Cause effective signature or endorsement to be rejected acceptance; Be because signature that requires to carry out or endorsement must be basic identical at every turn on the other hand, for the fake producer provides the chance of faking.Signer or endorsement person's signature or endorsement information is no matter how unique, in case seen signature or endorsement information by illegal person, the exercise through certain hour can realize the imitation for signature or endorsement information fully.And be to compare by human eye to judge for the validation of the letter of credit, cashier's cheque, check now.The safety technique that obvious existing ticket adopted can not provide safeguard for the Secure Transaction function that realizes bill.

Use the replacement signature that carves a seal for many years in China, though guaranteed the consistance of each signature, owing to carve a seal too easily by imitated, so and dangerous.Even through the administrative intervention of government, take the administrative authorization mode to specify and have only professional could carry out the business of carving a seal, but can not stop illegal person's imitated behavior owing to the technical not high of itself through authorizing.

Though extensively popularizing of the development of modern network technology and internet is for the development of financial circles brings new opportunity.Like Internet-based banking services and for the electronic key authentication techniques that guarantee Internet-based banking services safety are just becoming the important directions that modern finance already develops, but the safety that also greatly threatening Web bank such as network hacker, virus, fishing program simultaneously.Be still the major transaction instrument of modern finance industry based on the business transaction of financial document.

Summary of the invention

Technical matters to be solved by this invention is how to strengthen the safety of electronic bill and how to guarantee the signing messages of electronic bill and/or the security and the validity of endorsement information; And realize effective circulation of electronic bill with the mode of a kind of easy identification and use; To reduce the risk in the electronic bill use, promote the development of modern finance industry.

Embodiment:

Further describe specific embodiments of the present invention below in conjunction with accompanying drawing.

Fig. 1 is that Electronic Signature of the present invention is realized synoptic diagram for first kind.Electronic Signature 100 comprises information processing apparatus 101 and print module 102, and print module 102 is connected with said information processing apparatus 101, and print module 102 can print information on medium.Print module 102 have one print that surface of contact 110 contacts with medium or near.When signing electronically, the printing surface of contact 110 of print module 102 contacts with the specific region, and signing messages is printed on specific region 2302.Said information processing apparatus 101 comprises the rivest, shamir, adelman module and has stored the private key information of signing messages, signature owner; By said rivest, shamir, adelman module said signing messages, said private key information are carried out calculation process and obtain output information, convert said output information into signed data that said print module 102 prints by said information processing apparatus 101.The signed data of printing can be rendered as a string data usually and be convenient to the human eye perception.But the automatic identification of the inconvenient machine of a string data; Therefore the signed data of printing preferably is with modes such as bar code or two-dimensional bar codes and can adopts now corresponding bar code scanner or two-dimensional bar code reader to carry out automatic reading easily, can realize the automatic identification of signing messages.In this scheme, the public key information of signer is a public information, and can decipher this information with the public key information of signer and obtain raw information.Therefore can differentiate the true and false of the signing messages that Electronic Signature signs automatically through machinery and equipment.

Fig. 2 is that Electronic Signature of the present invention is realized synoptic diagram for second kind.Implementation than Fig. 1; In the implementation of Fig. 2; Electronic Signature 200 has increased by first fixed support 202 and second fixed support 203, and the Electronic Signature main body that comprises information processing apparatus 101 and print module 102 can be slided on first fixed support 202 and second fixed support 203.When not only printing the Electronic Signature main body, said first fixed support 202 and second fixed support 203, but also be convenient to aiming at and the location of print module 102 and specific region as the supporting & stablizing effect.Such as, on electronic bill, set a position reference point, through confirming the relative position of RP and first fixed support 202 and/or second fixed support 203, can both signing messages be printed to specific region 2302 in the time of just can guaranteeing to sign at every turn.
