Embodiment Construction

[0028] A secure partition storage device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] The invention discloses a storage device for secure partitions, such as figure 1 As shown, in this embodiment, the device is an SD card, including an SDIO module 11, a control module 12 and a storage module 13, and the three are connected through a hardware circuit and packaged into a standard SD card. Described storage module 13 is divided into:

[0030] The public partition 131 is used to store public data, and carry out data communication according to an ordinary SD memory card;

[0031] The private partition 132 is used to store private data. First, verify the preset personal application PIN. If the verification is passed, the storage partition will be identified by the operating system, and the startup address of the device will be changed from the starting address of the public partition 131 ...

Abstract

The embodiment of the invention discloses a storing device of safety partitions, and belongs to the field of data storage. A storing module of the storing device is divided into a public partition, a private partition, a read-only partition, a write-only partition and a conceal partition, wherein the private partition is used for storing private data, the read-only partition is used for storing solidified read-only data, the write-only partition is used for storing written-in write-only data, the conceal partition is used for storing invisible data, and special commands are used for conducting reading and writing, so that storage and read-write control are respectively carried out on input data through the storing device according to different access permissions, and the safety performance of the storing device is accordingly improved.

Description

technical field [0001] The present invention relates to the field of data storage, in particular to a secure partition storage device. Background technique [0002] SD card (Secure Digital Memory Card) Chinese translation is a safe digital card, which is a new generation memory device based on semiconductor flash memory, which is widely used in portable devices, such as digital cameras, personal digital assistants (PDA) and multimedia players, etc. SD card (Secure Digital Memory Card) is a memory card based on semiconductor flash memory technology, and has become the most widely used memory card in consumer digital devices. SD card is a multi-functional memory card with many features such as large capacity, high performance, and security. Compared with MMC card, it has a password authentication function (SDMI specification) for data copyright protection, and its read and write speed is 4 times faster than that of MMC card. , up to 2M / sec. [0003] The structure of the SD ...
