Problems solved by technology

[0005] For broadcast-type firmware downloads and upgrades, its business will cover a large area of ​​users, which also means that security risks will increase greatly. For example, hackers or other illegal users can steal or crack the password of the download server. Replace the downloaded firmware with illegal software or implant viruses in it, or set up fake base stations to intercept air firmware information, maliciously tamper with the firmware to be downloaded, and spread it in a large area through air download technology. If the terminal uses maliciously tampered firmware , which will cause immeasurable losses to operators and users
However, there is currently no technology that effectively addresses the security issues of over-the-air firmware downloads

Embodiment 1

[0033] According to an embodiment of the present invention, a firmware download preprocessing method based on an over-the-air technology is provided, which is used for a terminal to perform secure preprocessing on firmware downloaded over the air.

[0034] Such as figure 2 As shown, the firmware download preprocessing method according to the embodiment of the present invention includes:

[0035] Step S202, perform pre-processing (preferably, perform HASH algorithm) on the firmware to be downloaded, and generate summary data;

[0036] Step S204, taking the firmware to be downloaded and summary data as air information for the terminal to download.

[0037] In the above processing, the network side may also encrypt the generated summary data, and use the encrypted summary data and the firmware to be downloaded as air information for the terminal to download.

[0038] It can be seen from the examples given above that by using the summary data and the firmware to be downloaded t...

Embodiment 2

[0040] According to an embodiment of the present invention, a firmware integrity verification method based on an over-the-air technology is provided, which is used for a terminal to verify the integrity of firmware downloaded over the air. image 3 The process of this method is shown:

[0041] Such as image 3 As shown, the firmware integrity verification method according to the embodiment of the present invention includes the following processing:

[0042] Step S302, downloading air information from the network side, wherein the air information includes firmware and first summary data;

[0043] Step S304, perform predetermined processing on the firmware (preferably, execute a hash algorithm, and the hash algorithm is the same as the hash algorithm used by the network side to generate the first summary data), and obtain the second summary data;

[0044] Step S306, comparing the first summary data with the second summary data, and if the two are consistent, it is determined t...

Embodiment 3

[0048] According to an embodiment of the present invention, a method for downloading firmware based on an over-the-air technology is also provided. Figure 4 is a flowchart illustrating the processing of the method.

[0049] Such as Figure 4 As shown, the firmware download method according to the embodiment of the present invention includes the following processing:

[0050] Step S402, transmit the firmware to be downloaded to the firmware download server, perform predetermined processing (preferably, HASH algorithm) on the firmware to be downloaded, and generate first summary data;

[0051] Step S404, using the firmware to be downloaded and the first summary data as air information for terminal download; (the above is the data preparation process on the network side)

[0052] Step S406, the terminal downloads the air information through the wireless channel, and obtains the firmware and the first summary data in the air information;

[0053] Step S408, the terminal execut...

Abstract

The present invention discloses firmware downloading preprocess method based on OTA technology, firmware integrality verification method and firmware downloading method. In mentioned firmware downloading method, executing predefined process for downloading firmware to generate first summarization data; the downloading firmware and first summarization data are taken as aerial information for terminal downloading; terminal downloads aerial information by wireless channel and acquires firmware of aerial information and first summarization data; terminal executes predefined process to firmware for generating second summarization data; terminal judges integrality checking of firmware by comparing consistency between first summarization data and second summarization data when both summarization data are consistent. The present invention can improve safety of aerial downloading firmware.

Description

technical field [0001] The present invention relates to an Over the Air (OTA) technology in the field of wireless communication, in particular to an OTA-based firmware download preprocessing method, a firmware integrity verification method, and a firmware download method. Background technique [0002] Over the Air (OTA for short), as an over-the-air upload and download technology closely related to mobile terminals, is attracting increasing attention, and with the continuous improvement of mobile terminal functions, OTA technology will also become more and more It is widely used in mobile services. [0003] Mobile terminal users can use OTA technology to upload and download data, install various applications, download pictures / ringtones, upgrade firmware and other functions. OTA undoubtedly provides technical support for remote firmware loading and information uploading of mobile terminals, reducing the Operational maintenance and upgrade costs. However, the openness of th...
