Abstract
An electronic device includes a processor and one or more secure elements. The processor executes a first high-level operating system and a first application. The one or more secure elements execute a first low-level operating system to verify a reliability, an authenticity, or a reliability and an authenticity of the first high-level operating system, and execute a second low-level operating system to execute a second application and to perform wireless communication with the first application. At each booting of the electronic device, the first low-level operating system performs a verification of the reliability, of the authenticity, or of the reliability and the authenticity of the first high-level operating system. In response to a request from the first application to the second application, the second low-level operating system requests a result of the verification from the first low-level operating system, and transmits the result to the second application.
