Abstract: A terminal includes a security subsystem, a baseband processor, and a first bidirectional bus coupled between the security subsystem and the baseband processor. The security subsystem is configured to manage at least one of data related to a user identity or data related to network security in wireless communication, and exchange the data with the baseband processor by using the first bidirectional bus. The baseband processor is configured to exchange the data with the security subsystem by using the first bidirectional bus, and implement wireless communication by using the data. The security subsystem and the baseband processor are in the same hierarchy. The security subsystem may proactively perform data transmission by using the first bidirectional bus.

Abstract: A system on chip is integrated on a first semiconductor chip, and includes: a system bus, at least one processor coupled to the system bus, and a security processor system coupled to the system bus. The security processor system includes a security processor, a first memory, multiple interfaces, and a security bus, where the security processor, the first memory, and the multiple interfaces are coupled to the security bus, and the security bus is coupled to the system bus. The security processor is configured to execute security operating system software and at least one security software application based on the security operating system software, where the at least one security software application includes mobile payment software used to implement mobile payment. The multiple interfaces include a near field communication (NFC) interface and a biometric recognition input interface.
