Method and apparatus for accessing storage space

Abstract

The present invention discloses a method and apparatus for accessing a storage space, so as to improve the storage security of private data on a terminal. The method is applied to the terminal configured with the storage space, and a running environment of an operating system of the terminal comprises a secure environment and an insecure environment. The method comprises: according to indication information pre-stored in a storage space, determining that the storage space is a secure storage space, wherein the indication information is used for indicating a secure attribute of the storage space; prohibiting registering the secure storage space in a device registry in an insecure environment; and accessing the secure storage space according to an access request sent by a trusted application TA running in a secure environment. The apparatus comprises a determining module, a registration module, and an access module. The determining module, the registration module, and the access module are used for carrying out the method described above.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, to a method and device for accessing storage space. Background technique [0002] With the development of mobile terminals such as mobile phones and tablet computers, the storage of private data such as fingerprints and Alipay has become an important issue that people care about. In the mobile terminal, the storage area used to store security information is exposed in the device table of the mobile terminal. Therefore, the access to this storage area is carried out in an unsafe operating environment. Keys and accessed private data are easily stolen or destroyed by attackers, resulting in the leakage of user private data and causing great losses to users. [0003] Therefore, in current mobile terminals, the security of the storage space needs to be improved urgently. Contents of the invention [0004] Embodiments of the present invention provide a method a...
