Abstract: An electronic device and a trusted application calling method are provided. After a client application initiates call information, a trusted application development platform receives the call information, determines a native trusted application corresponding to first identification information of the electronic device carried by the calling information from native trusted applications corresponding to at least two (or more) TEE OSs connected to the trusted application development platform, and sends the calling information to the native trusted applications corresponding to the first identification information. The native trusted application corresponding to the first identification information receives the calling information, determines a bytecode trusted application corresponding to the second identification information from at least one bytecode trusted application installed in the native trusted application according to the second identification information carried by the calling information, and calls the bytecode trusted application corresponding to the second identification information.

Abstract: 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.
