Embodiment Construction

[0036] The present invention provides a mobile terminal security information storage method and system based on an EMMC chip. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The mobile terminal security information storage method and system based on the EMMC chip of the present invention, by writing the key at the PC end in advance, when the RPMB information of the mobile terminal EMMC chip needs to be modified, the key needs to be written from the PC end, because it is controlled by the PC This key avoids the possibility that other people crack the code of the mobile terminal to obtain the key and modify the RPMB information of the mobile terminal, thus greatly improving the security of the EMMC c...

Abstract

Disclosed are a mobile terminal security information storage method and system on the basis of an EMMC chip. According to the present invention, a key is set in a PC terminal, and if intending to modify RPMB information, a user needs to download the key in the PC terminal through a mobile terminal, so that the security of a related security information document in the mobile terminal is greatly improved. The present invention is simple and easy to operate and has high practicality.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an EMMC chip-based mobile terminal security information storage method and system. Background technique [0002] With the rapid development of mobile terminal industries such as mobile phones and PDAs, the market is flooded with a large number of flash memory chips of different specifications, and these memory chips do not have a fixed standard, which leads to problems in the project development process. Memory chip, hardware must be redesigned wiring (layout), thus bringing development costs and development efficiency to the project in many ways. [0003] The birth of the EMMC (Embedded MultiMediaCard) chip made up for this defect. The EMMC chip refers to an embedded multimedia file storage device, which has gradually become the mainstream solution in the current smart phone market. The EMMC chip is an embedded storage standard specification established by the MMC Associat...
