A method and a system for writing a Keybox parameter into Android equipment

Abstract

The invention relates to a method and a system for writing a Keybox parameter into Android equipment. The method comprises the following steps: analyzing an Attestation Keybox file and a Widevine Keybox file which are obtained in advance; Combining the analyzed contents of the Attestation Keybox file and the Widevine Keybox file into a plurality of combined Keybox files named by the Devine Keyboxfile, wherein the combined Keybox files are named by the Devine Keybox; pushing The combined Keybox file into an Android device; And writing the combined Keybox file from the push to the Android device into the Android device. According to the method, the research and development difficulty of the parameter writing tool and the complexity of operating the parameter writing tool by an operator arereduced, the Keybox writing efficiency is improved, the production yield is improved, and the phenomenon of reworking and rewriting the Keybox is reduced.

Description

technical field [0001] The invention relates to the technical field of Android device parameter setting, in particular to a method and system for writing Keybox parameters in an Android device. Background technique [0002] Android Keybox mainly refers to Attestation Keybox for Google authentication service and Widevine Keybox for digital copyright DRM service. It uses the device id to establish an association, that is, the Attestation Keybox and Widevine Keybox with the same device id need to be written to the same device. Both of these Keyboxes need to be applied to Google in batches before the project is produced and written to Android devices before leaving the factory. The storage location and usage method of the Keybox data are determined by the chip manufacturer used by the Android device, which is implemented in accordance with Google standards. Only after correctly writing to the Keybox can it pass Google's CTS certification. [0003] The existing Keybox manageme...

Problems solved by technology

[0004] Since the Attestation Keybox and Widevine Keybox applied for in batches from Google are both large file data in xml format, when writing Keybox, you must first query the corresponding Keybox data from the large xml file according to the device id, and then write it in. The other two Keybox needs to execute two queries and two writes. This query and write has the defects of high time cost and difficult design and development when writing parameter tools.
