Problems solved by technology

[0003] With the continuous development of Internet technology, the network security situation is becoming more and more serious. The home gateway is the first checkpoint connecting the Internet and end users. Rapid recovery and removal of viruses will cause very serious information security problems for home gateway users
[0004] Since home gateway devices usually use fixed remote control channels and upgrade protocols, they are easily blocked by virus programs, causing operators to lose remote control rights to gateway devices, unable to quickly and effectively remove virus programs, and can only go door-to-door Upgrading offline one by one is not only inefficient but also consumes a lot of manpower and financial resources
The more serious problem is that the virus program has been lurking in the home gateway equipment for a long time, which will cause very serious information security problems for users

Embodiment 1

[0056] refer to figure 1 , the recovery method of the present embodiment includes the following steps:

[0057] Step 101: Determine the recovery image and the identity feature code of the gateway device to which the recovery image is applicable.

[0058] In practical application scenarios, after a certain gateway device is attacked by a virus, the server will lose remote control of the gateway device. The controlled device is marked as the attacked gateway device, and obtains the identity feature code of the attacked gateway device, wherein the identity feature code includes but not limited to the chip identification code (chip ID) of the main chip of the gateway device, the MAC address of the network card , public network IP address or SN serial number burned at the factory. Among them, in the actual application scenario, the public network IP address can be static or dynamic. When the public network IP address is dynamic, the server end stores a dynamic change table of the...

Embodiment 2

[0118] Embodiment 1 describes the implementation process of the recovery method from the perspective of the server, focusing on the way of customizing the recovery image, performing data processing such as segmentation / encryption on the recovery image, the method of generating the recovery descriptor, and how to set each sub-recovery The target download domain name of the image. This embodiment focuses on describing how to obtain a recovery descriptor through a domain name request, and download a recovery image according to the recovery descriptor, and then perform system recovery on the gateway device.

[0119] refer to image 3 and Figure 4 , the restoration method includes the steps of:

[0120] Step 301: Request the record set corresponding to the target request domain name, and obtain the recovery descriptor associated with the target request domain name.

[0121] Specifically, combined with Figure 4 , step 301 specifically includes the following steps:

[0122] St...

Embodiment 3

[0160] see Figure 5 , Figure 5 It is a schematic structural diagram of a gateway device provided by an embodiment of the present invention. The gateway device in this embodiment includes one or more processors 51 and a memory 52 . in, Figure 5 A processor 51 is taken as an example.

[0161] Processor 51 and memory 52 can be connected by bus or other means, Figure 5 Take connection via bus as an example.

[0162] As a non-volatile computer-readable storage medium, the memory 52 can be used to store non-volatile software programs, non-volatile computer-executable programs and modules, such as the recovery method and corresponding program instructions in Embodiment 2. The processor 51 executes various functional applications and data processing of the recovery method in the second embodiment by running the non-volatile software programs, instructions and modules stored in the memory 52 to realize the function of the recovery method in the second embodiment.

Abstract

The invention discloses a recovery method and a recovery system for gateway equipment. The recovery method comprises the following steps of: determining a recovery mirror image and an identity featurecode of the gateway equipment suitable for the recovery mirror image; updating the recovery mirror image to a record set corresponding to the target downloading domain name; generating a recovery descriptor based on the identity feature code and the target download domain name, and updating the recovery descriptor to a record set corresponding to the target request domain name; and distributing the recovery mirror image and the recovery descriptor through the domain name distributed database so that the gateway equipment downloads the recovery mirror image through the recovery descriptor, andthen carrying out system recovery. According to the recovery method and the recovery system of the invention, through a mode of storing and publishing the recovery mirror image by using the DNS system, under the condition of not needing a special server, the recovery mirror image is safely transmitted in the whole Internet, and the purpose of quickly recovering the gateway equipment is achieved.

Description

technical field [0001] The invention belongs to the field of computer communication, and more specifically relates to a recovery method and system for gateway equipment. Background technique [0002] The Domain Name System (DNS for short) is a core service of the Internet. As a distributed database that can map domain names and IP addresses to each other, it can make people access the Internet more conveniently. [0003] With the continuous development of Internet technology, the network security situation is becoming more and more serious. The home gateway is the first checkpoint connecting the Internet and end users. Rapid recovery and removal of viruses will cause very serious information security problems for home gateway users. [0004] Since home gateway devices usually use fixed remote control channels and upgrade protocols, they are easily blocked by virus programs, causing operators to lose remote control rights to gateway devices, unable to quickly and effectively...
