Abstract

The present invention relates to computer technology, especially to the implementation of a switching method between an untrusted environment and a trusted environment in a mobile device and the mobile device which implements the method. According to an embodiment of the present invention, the method comprises the following steps: detecting whether a first switching command is received from an external device to indicate the mobile device to switch from the untrusted environment to the trusted environment; if the first switching command being detected, the first switching operation, which comprises saving the context of the untrusted environment, being operated from the untrusted environment to the trusted environment; and the mobile device executing the security application indicated by the external device in the trusted environment to execute business process.

Description

technical field [0001] The invention relates to computer technology, in particular to a method for switching between an untrusted environment and a trusted environment in a mobile device and the mobile device for realizing the method. Background technique [0002] With the rapid development of broadband wireless access technology and mobile terminal technology, the mobile Internet has emerged as the times require and has become the fastest growing market with the greatest potential and the most attractive prospects. Businesses based on the mobile Internet are penetrating into every aspect of people's daily life, such as socializing, shopping, financial transactions and life information acquisition. Many mobile Internet services involve the storage, reading, and transmission of sensitive information (such as user privacy, login identities, and passwords, etc.), so security mechanisms need to be provided for protection. [0003] In existing mobile devices, security applicatio...
