Description

Electronic contract managing system operation platform
Technical field
The present invention relates to a kind of operation platform, specifically, relate to a kind of operation platform of electronic contract management system.
Background technology
Along with developing rapidly of ecommerce, the signing of traditionally on paper contract and the more and more progress of influence commercial affairs of management, people begin to use in a large number electronic document, e-file and electronic data to replace the file and the exchanges data of papery, and this has become a kind of inevitable development trend.But safety problem wherein also becomes increasingly conspicuous, and how to solve the problem of signing and sealing of e-file, and how to guarantee that the problems such as authenticity, integrality, reliability and non repudiation of various e-files become the bottleneck that the restriction e-file uses comprehensively.
Many countries have all formulated the electronic signature method, and the prelude that China Electronics's contract is used has been drawn back in the enforcement of " People's Republic of China's law of electronic signature " of China.The application of electronic contract is the phase one that digital paper is expanded its application, and it makes the digital paper technology tentatively show its powerful influence power in information-based field.
Electronic signature is not to be the digital pictureization of written signature.It is a kind of electronic code in fact, utilizes it, and the addressee just can easily verify sender's identity and signature on the net.It has realized the confidentiality of information transmission, the integrality of exchanges data, the non-repudiation that sends information, the determinacy of dealer's identity.
At present, can realize electronic signature by the multiple technologies means, but comparative maturity, easy to use have an operability, and the electronic signature technology that generally uses in advanced country in the world and China also is based on the digital signature technology of PKI (Public Key Infrastructure Public Key Infrastructure).
Electronic signature based on PKI (Public Key Infrastructure) is known as " digital signature ".Have person " electronic signature " be exactly " digital signature " be wrong.Digital signature is a kind of particular form of electronic signature just.Because though electronic signature has obtained the technology neutrality, but also bring the inconvenience of use, again further regulation has been made in electronic signature legally, just stipulated " reliable electronic signature " and " advanced electronic signature " in " instruction of electronic signature common frame " as " the electronic signature method of demonstration " of above-mentioned UNCTAD and European Union.In fact be exactly the function of having stipulated digital signature, this regulation makes digital signature obtain better application security and operability.At present, the electronic signature with practical significance has only the public key cryptography theory.So, at present both at home and abroad generally that use, technology maturation, can the actual digital signature technology that also is based on PKI that uses.Can provide multiple internet safe service as Public Key Infrastructure PKI, as authentication, data security, data integrity and non-repudiation.Wherein all used digital signature technology.
The core topworks of PKI is the digital certificate ISP, promptly is referred to as the CA of certification authority (Certificate Authority), and the central factor of PKI signature is the digital certificate of being signed and issued by CA.The PKI service that it provided is exactly authentication, data integrity, data security and non-repudiation.Its practice is exactly that certificate of utility PKI and corresponding with it private key carry out enciphering/deciphering, and produces signature and certifying signature to digital message.Digital signature is to utilize public key cryptography technology and other cryptographic algorithms generation series of sign and code to form electronic cipher to sign, to replace writing signature and seal; The signature of this electronic type also can carry out technical identification, and the accuracy of its checking is incomparable to the checking of manual signature and seal.This endorsement method can authenticate in very big credible PKI territory crowd, or carries out cross-certification in a plurality of believable PKI territory, and it is specially adapted to safety certification and transmission on internet and the wide area network.
Because the technology of Internet net (internet) e-commerce system makes the client of shopping on the net can extremely make things convenient for the information that obtains businessman and enterprise like a cork, but also increased simultaneously some risk responsive or valuable data are abused.The buyer and the seller must be true and reliable for operating in all financial transactions of carrying out on the Internet, and make transaction each side such as client, businessman and enterprise all have absolute confidence, thereby internet (Internet) e-commerce system must guarantee to have very reliable safe and secret technology, that is to say, must guarantee the elemental of network security, i.e. the integrality of the confidentiality of information transmission, exchanges data, the non-repudiation that sends information, the determinacy of dealer's identity.
Commercial matters information in the transaction all has secret requirement.Account number and user name as credit card are known that by the people just possibility is stolen, and the information of order and payment is learned by the rival, just may lose business opportunity.The requirement of encryption is generally all arranged during therefore the information in electronic transaction process is propagated.
The both sides of online transaction have never met before probably, a thousand li of being separated by.Make Transaction Success at first want to confirm the other side's identity, will consider that to businessman client can not be the cheat, and the client can worry that also online shop is an inn by brigands of playing with swindle.Therefore can confirm easily and reliably that the other side's identity is the prerequisite of transaction.For being bank, credit card company and the sale shop that client or user carry out service,, all to carry out the work of authentication in order to accomplish safety, maintain secrecy, to carry out service activity reliably.Concerning relevant sale shop, they are ignorant to the number of the used credit card of client, and the shop can only be given bank the affirmation work of credit card fully and be finished.Bank and credit card company can adopt various maintaining secrecy and recognition methods, confirm whether client's identity is legal, also will prevent simultaneously to refuse to pay the money problem and confirm order and order receipt information etc.
Because market conditions is ever-changing, transaction is in case reach and can not be denied.Otherwise will inevitably damage a side interests.Can for example order gold, price of gold be lower during order, but after receiving order, price of gold has gone up, acknowledge receipt of the real time of order as the acquirer, even denies receiving the fact of order, and then order party will sustain a loss.Therefore each link of electronic transaction communication process all must be undeniable.
The transaction file can not be modified, as above for example-order gold.Supply unit finds that price of gold has sharp risen after receiving order, can change file content as it, will order several 1 ton and change 1 gram into, then can significantly be benefited, and therefore the unit of order may sustain a loss so.Therefore the electronic transaction file is also wanted can accomplish and can not revise, to ensure the serious and just of transaction.
