(6) by using the log, information related to the transaction and error information during operation and communication are recorded, so that debugging and error detection are facilitated.
The safety technical principle in the electronic payment process of the invention is as follows:
(1) asymmetric encryption technology: asymmetric encryption, also known as public key encryption, means that a key is broken down into a pair, i.e. a public key (encryption key) and a private key (decryption key). Either one of the pair of keys may be made public to others in an unsecured manner as a public key (encryption key), while the other is kept as a private key (decryption key). The public key is used to encrypt the confidential information, and the private key is used to decrypt the encrypted information. Anyone can encrypt information using a public key, but only the owner of the private key that matches the public key can decrypt the information. At present, the commonly used asymmetric encryption algorithm is the RSA algorithm, which has been recommended by the SIO/TC data encryption technical division committee s 0 as the asymmetric key data encryption standard. .
(2) The security authentication technology comprises the following steps: authentication technology is an effective method for preventing information from being falsified, deleted, reproduced, and forged, and provides a transmitted message with the ability to be verified, enabling a recipient to recognize and confirm the authenticity of the message. Its implementation includes techniques such as digital signatures, digital certificates, etc.; the digital signature technology adopts an encryption and decryption algorithm system of an encryption technology to realize digital signature on the message. The digital signature can realize the following functions that the receiver can verify that the sender can not deny the sent message after the real identity of the sender, and the receiver or an illegal person can not forge or falsify the message. When two parties dispute about the authenticity of the signature, the third party can solve the dispute Sichuan digital certificate between the two parties, and the identity of a user and the access authority to the network resource are verified by an electronic means. A set of strict identity authentication system is established by using a digital certificate and by applying cryptographic technologies such as a symmetric cryptosystem and an asymmetric cryptosystem, so that information is not stolen by other people except a sender and a receiver; the information is not tampered in the transmission process; the sender can confirm the identity of the receiver through the digital certificate; the sender cannot repudiate the own information, etc.
(3) Secure sockets, which may be referred to as cryptographic communication protocols for short. The communication (including E-mail) content can be encrypted with high intensity by using SL to prevent hackers from monitoring the communication content and even the user password; the SLs protocol is a data security protocol between TCP/PI and various application layer protocols, and can be divided into two layers. The SSL recording protocol of the lower layer is established on a reliable transmission protocol (such as CTP), and provides support for basic functions of data encapsulation, compression, MA C (MA C) and encryption and the like for a higher layer protocol; the services provided by the SSL protocol can be summarized into three aspects of legality authentication of the user and the server, encryption of data, and protection of the integrity of the data z [ ]. sLs is independent of the application protocol, and a higher layer protocol can be transparently located on top of the SL protocol.
The electronic payment system of the invention is an important component and bottleneck mouth of an electronic commerce system, which means that consumers, merchants, financial institutions and the like exchange goods or services by using a safe electronic means, namely, payment information of a novel payment means (comprising electronic cash, credit cards, debit cards, intelligent cards and the like) is safely transmitted to banks or corresponding processing mechanisms through a network to realize electronic payment.
The invention designs and realizes an available payment interface by using security technologies and communication technologies such as an SL protocol, a digital certificate, a digital signature and the like, overcomes the defect that password is easy to steal in the traditional authentication mode of teller number + password, and has the characteristics of less resource occupation, simple implementation and maintenance, strong system stability and the like.
The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present invention are included in the scope of the present invention.
