Embodiment Construction

[0008] The generation process of online electronic invoice is as follows: (see Figure 1)

[0009] In the first step, the issuer of the electronic invoice obtains the private key KR used by the issuer for digital signature and the digital certificate used by the recipient for encryption.

[0010] The issuer of the electronic invoice must obtain the private key string KR used to sign the invoice data and the corresponding digital certificate Certificate used to identify the holder before issuing the invoice. The digital certificate contains the public key string KP used to verify the signature of the private key. Digital certificates are generally issued by an authoritative certificate authority (CA) to prove the identity of the certificate holder to a third party. Digital certificates can be downloaded from the download address provided by the certificate authority, or obtained by other means. The private key can be obtained by the issuer using a key generation device (such a...

Abstract

This invention relates to one electro invoice generation and interacting use method based on communication network, wherein, the invoice is for internet transmission electron invoice with similar content to paper invoice with generation process of symmetric and asymmetric code technique; the invoice has connection internet function process device; user can interact with other internet terminal and electron invoice process device; processing electron invoice buying, issuing, canceling, discounting, storing and inquire steps; processing data interacting to national tax department or business ERP system, bank and customs.

Description

technical field [0001] The invention relates to a method for generating and interactively using an electronic invoice based on a communication network. It belongs to the application field of network security technology Background technique [0002] The generation and interaction method of electronic invoices on the Internet is based on the security framework - public key infrastructure (PKI). Public Key Infrastructure (PKI) is the most feasible and effective way to solve information security problems in a large open network environment. PKI is a system that uses public key technology and digital certificates to ensure system information security and is responsible for verifying the identity of digital certificate holders. PKI adopts the trust mechanism that each participant trusts the same CA (certification center), and the CA checks and verifies the identity of each participant. Through public key infrastructure (PKI), the two parties to the transaction (possibly between...
