Embodiment 1

[0042] Such as figure 2 As shown, the security device for storing invoices is used to solve the anti-counterfeiting project of Chinese characters in the anti-counterfeiting tax control system:

[0043] 1) First, the tax authority issues a USBkeyS1 to the taxpayer. According to the Chinese character anti-counterfeiting project, the tax control function area needs to be divided and the taxpayer's identity information is written.

[0044] 2) The taxpayer connects the USBkeyS1 to the enterprise system S2. When issuing an invoice, the invoice details and the anti-counterfeit QR code are verified by the authority and stored in the USBkeyS1 invoice area through the COS system, and the printing device S3 is used to print the VAT invoice.

[0045] 3) When copying tax, compare and verify the golden tax card storage authentication data that needs to declare tax invoices with the invoice data and QR code stored in USBkeyS1, generate tax declaration files and error comparison files, and s...

Embodiment 2

[0048] Such as image 3 As shown, the method of applying the security device for storing invoices to the network billing system:

[0049] 1) First, the tax authority issues a USBkeyS1 to the taxpayer, divides the functional area according to the needs of the network billing system, and writes the billing control file, ticket number resource information, taxpayer identity information, certificate and key information, etc.

[0050] 2) The taxpayer connects the USBkeyS1 to the enterprise system S2. When issuing an invoice, it needs to read the invoicing control and ticket number resource information from the USBkeyS1 after passing the authority verification, and then transfer the invoice details to the invoice area of ​​the USBkeyS1. The USBkeyS1 according to the invoice details The data calculation tax control code and invoice signature are returned to the enterprise-side system S2, and the enterprise-side system S2 calls the printing device to print the invoice.

[0051] 3) Wh...

Abstract

An embodiment of the invention provides a security device for storing an invoice. The security device includes a COS system, a file management module, a password service module and a key management module; the COS system manages a memory chip and a security chip, so that the security chip can have the same level of security protection as the internal memory of the memory chip does; the file management module provides functions of creating and deleting a file, reading and writing a binary file, and reading and writing special files such as invoice data; the password service module provides functions of symmetric encryption and decryption, asymmetric encryption and decryption and signature and signature test; and the key management module provides the functions of producing a symmetric key and an asymmetric key, and importing and exporting the symmetric key. The security device for storing the invoice integrates the tax control district function and smart password key function, adopts strict security policies and ensures the security, integrity, availability and non-repudiation of the invoice data, so that the memory chip can have the same level of security protection as the internal memory of the security chip does.

Description

technical field [0001] The invention relates to the field of information security, in particular to a security device for storing invoices. Background technique [0002] In order to further strengthen the management of special value-added tax invoices and effectively prevent criminals from tampering with Chinese character information and falsely issuing special value-added tax invoices, the invoicing subsystem of the value-added tax anti-counterfeit tax control system has been upgraded to a Chinese character anti-counterfeit invoice system. That is, without changing the password system of the existing anti-counterfeiting tax control system, digital passwords and two-dimensional code technology are used to replace the original 84-bit and 108-character ciphertexts with two-dimensional codes that store more information. On the basis of the element information, the functions of encryption, collection of tax returns and decryption of information such as the name of the buyer's co...
