An electronic device, a trusted application calling method and apparatus, a device, and a medium are disclosed. Because a trusted application development platform is linked with native trusted applications respectively corresponding to multiple trusted execution environment operating systems (TEE OS), based on the trusted application development platform, a bytecode trusted application can be applicable to any TEE OS, and for different TEE OS hardware platforms, only one corresponding bytecode trusted application needs to be developed for one application. Moreover, the trusted application development platform and the byte code trusted application can be applied to electronic devices (terminals) of different TEE OSs.

Electronic device, trusted application calling method and apparatus, device, and medium

A non-contact communication method and a communication device are presented. The communication device includes a trusted execution environment (TEE). A first security application and a second security application are provided in a security element of the communication device. The first security application and an application in the trusted execution environment are communicationally connected by means of a first communication channel. The second security application and a near-field communication (NFC) module provided in the communication device are communicationally connected by means of a second communication channel. The first security application and the second security application are communicationally connected by means of a security channel. Using the non-contact communication method and the communication device, a security channel may be established between NFC and a TEE, which may enable NFC non-contact card reading for a TEE application.

Non-contact communication method and communication device

The invention discloses a method for realizing virtual secure element (VSE), which comprises the following steps: a secure element manager (SEM) generates a request which comprises virtualized configuration information; and a virtual machine monitor in a hypervisor allocates an address space for the VSE according to the above request.

Method for implementing virtual secure element

The invention relates to management of programs on a mobile device, and in particular, to a method for activating application programs on a mobile device, and a mobile device based on this method. The method for activating application programs on a mobile device according to an embodiment of the invention comprises the following steps: receiving an application request from a device which is located outside the mobile device; identifying a transmission protocol associated with the application request; and if there are a plurality of safety entities in the mobile device which support the transmission protocol and store application programs associated with the application request, activating an application program associated with the application request in a default safety entity.

Starting an application on a mobile device

The invention proposes a security information interaction system, apparatus and method based on security carrier's active command. The method comprises: an information interaction terminal, based on a user's command, establishes a security dialog channel between the information interaction terminal and a security carrier so as to perform a security information interaction process, wherein the user's command indicates a target application associated with the security information interaction process; and the security carrier activates the target application during the establishment of the security dialog channel and then executes the security information interaction process based on the security dialog channel. In the security information interaction system, apparatus and method based on security carrier active command disclosed in the invention, the security carrier can initiate an active command to the information interaction terminal.

Security information interaction system, device and method based on active command of secure carrier

The invention relates to communication technology, and in particular, to a method of establishing communication connection between a mobile device and a secure element as well as a mobile device for implementing the method. The method comprises the following steps: when the mobile device detects that there is a secure element which establishes a physical connection with it, the mobile device performs a secure authentication on the secure element; if the secure authentication passes, the mobile device determines whether there is configuration information inside it which is required for establishing the communication connection between the mobile device and the secure element; and if there is the required configuration information inside the mobile device, the mobile device uses the configuration information to establish the communication connection with the secure element; otherwise, the mobile device obtains required configuration information from the secure element to establish the communication connection with the secure element.

Establishment of communication connection between mobile device and secure element

The invention provides an apparatus used for security information interaction comprising a first system management device for providing an operational environment for routine applications and a second system management device for providing an operational environment in a safe mode for security applications so as to perform a security information interaction process. The apparatus used for security information interaction disclosed by the invention has a high safety and a wide applicability and is low in cost.
