Embodiment 1

[0017] Embodiment 1. A method for safely online upgrading tax control equipment software, the process of which is as follows figure 1 shown.

[0018] figure 1 In S100, the tax control equipment software upgrade terminal encrypts the tax control equipment identification with the first key, and sends a tax control equipment verification request carrying the encrypted tax control equipment identification to the tax control equipment software upgrade network terminal.

[0019] Specifically, the tax control device software upgrade terminal in this embodiment may be a tax control device, or may be a tax control device and an intelligent electronic device (such as a computer or a smart phone, etc.) connected to it. The tax control equipment software upgrade terminal (that is, the terminal in the following description) can use a wired method (such as a serial interface or a USB interface) or a wireless method (such as WIFI mode) to upgrade the network terminal of the tax control equi...

Embodiment 2

[0047] Embodiment 2. A method for safely online upgrading tax control equipment software, the process of which is as follows figure 2 shown.

[0048] figure 2In S201, the network side (such as the server of the tax department) performs software upgrade authorization for the terminal (such as the user's tax control equipment), that is, the network side will authorize the authorization information for the terminal software upgrade (such as the number of upgrades and the deadline for upgrading, etc.) It is transmitted to the terminal so that the authority information can be configured in the terminal. In practical applications, the network side can use its stored terminal public key to encrypt the permission information, and transmit the encrypted permission information to the terminal, and the terminal uses its terminal private key to decrypt the permission information and store the decrypted permission information. information.

[0049] S202. The terminal uses the locally ...

Embodiment 3

[0061] Embodiment three, tax control equipment software safety online upgrade system, the system is as follows image 3 shown.

[0062] image 3 Among them, the tax control equipment software security online upgrade system mainly includes: tax control equipment software upgrade network terminal and multiple tax control equipment software upgrade terminals. The tax control equipment software upgrade terminal here may be the tax control equipment, or the tax control equipment and the intelligent electronic equipment connected thereto. Here, the tax control equipment software upgrade network end can be a server.

[0063] The tax control equipment software upgrade network mainly includes: a first decryption module 300 , a software upgrade control module 310 , a first communication module 320 and a rights management module 380 .

[0064] The tax control equipment software upgrade terminal includes: a second communication module 330 , an identity authentication request module 340...

Abstract

The invention provides a secure online upgrade method and system for tax control equipment software. The secure online upgrade method comprises the steps that: a terminal sends a tax control equipment identifier that is encrypted based on a first key to a network end; the network end decrypts the tax control equipment identifier via a second key, and sends a communication key that is encrypted based on a third key, an upgrade data packet that is encrypted based on the communication key and a digital signature to the terminal, when determining that the tax control equipment identifier is a credible tax control equipment identifier and that the terminal has software upgrade authority; the terminal decrypts the communication key via a fourth key, obtains an upgrade data packet plaintext via the communication key, obtains a first abstract corresponding to the digital signature via the communication key and the first key, and executes an upgrade operation of the tax control equipment software, when determining that the upgrade data packet plaintext is a complete and effective upgrade data packet plaintext according to the first abstract and a second abstract that is calculated based on the upgrade data packet plaintext. The secure online upgrade method provided by the invention is used for guaranteeing the security and integrity of data transmission in an upgrade process and reducing the upgrade cost of the tax control equipment software.

Description

technical field [0001] The present invention relates to tax control equipment software upgrade technology, in particular to a tax control equipment software safe online upgrade method and system. Background technique [0002] With the adjustment of the national tax policy, the software of tax control equipment usually needs to change accordingly. Therefore, the software of tax control equipment should be upgraded in time to meet the requirements of the current tax policy. [0003] In the case that the tax control equipment has been delivered to the user, there are usually two ways to upgrade the tax control equipment software: method 1, the user goes to the local tax department to replace the tax control equipment with the new version of the software; method 2, the user will tax The tax control equipment is provided to the corresponding after-sales service unit, and the professionals of the after-sales service unit will upgrade the software of the tax control equipment.
