  • Method and an integrated circuit for executing a trusted application within a trusted runtime environment
    Patent number: 9927995
    Abstract: A method and an integrated circuit (100) for executing a trusted application within a trusted runtime environment (103) of the integrated circuit (100) are disclosed. The integrated circuit (100) comprises an internal memory (101) and the integrated circuit (100) is connected to an external memory (102). The trusted runtime environment (103) is restricted to use the internal memory (101) and the external memory (102). The integrated circuit (100) identifies (201) a call, by the trusted application, to a command of the trusted runtime environment (103). The trusted runtime environment (103) allows the command to be executed when the trusted application resides in the internal memory (101) only. Next, the integrated circuit (100) executes (204) the command while using the internal memory (101) only.
