Abstract: A host controller, a secure element, and a serial peripheral interface communications system are provided. The host controller is configured to connect to a secure element via a serial peripheral interface and includes: a resume signal generator configured to generate a first resume signal indicating a start of communication with the secure element; a transmitter configured to transmit the first resume signal to the secure element; a slave select line activator configured to activate a slave select line after the first resume signal is transmitted; and a clock controller configured to transmit a first clock signal to the secure element over a clock line based on the slave select line being activated, and the transmitter is further configured to transmit a first signal containing first data to the secure element over a master-out slave-in line (an MOSI line) while the first clock signal is being transmitted.

Abstract: A remote control method between mobile devices and a system thereof are provided. The system includes a server including a control command list for controlling a help-requesting device. The server authenticates a remote control authorization of a control device and relays a data packet communication between the help-requesting device and the control device. The help-requesting device transmits a help request message to the control device through the server. The control device acquires the authorization to remotely control the help-requesting device from the server and then transmits a control command for controlling the help-requesting device to the help-requesting device through the server. The help-requesting device executes the received control command and then transmits execution result data to the control device through the server. The control device outputs the execution result data received from the help-requesting device.
