Abstract

The invention relates to control technology for a storage card, in particular to a controller special for the storage card and a control system for the storage card and a relevant control method applying the same. The controller special for the storage card comprises a card reader controller which is installed with a software program, and the software program is saved in a storage of the card reader controller and runs in a CPU of the card reader controller, so that the controller special for the storage card has the functions of mutual authentication of the controller special for the storage card and the storage card and encryption of data in the storage card, can save operation log data in a storage area of the card reader controller and is convenient for tracking the data. According to the technical proposal, compared with the card reader of the storage card in the prior art, the invention has higher safety and stronger calculation function.

Description

technical field [0001] The invention relates to memory card control technology, in particular to a dedicated memory card controller, a memory card control system using the controller and a related control method. Background technique [0002] Driven by the multimedia application of portable electronic products such as digital products and mobile phones, the mobile storage market is booming. Authenticated data access. Therefore, dedicated memory cards with secure computing functions emerge as the times require. The dedicated memory card at least includes a CPU (processing unit), FLASH memory, I / O interface (including USB interface and UART interface), and application programs. The I / O interface of the dedicated memory card not only has a memory card communication interface, such as an SD or MMC interface, but also at least has an ISO / IEC 7816 communication interface and a USB communication interface. There are control modules for each interface in the card, and various inte...
