A secret key device (100), a data switching apparatus (300), a data interaction component, a data interaction system and a device starting method. The secret key device (100) comprises a built-in power supply (110) and an external interface (120), wherein the external interface (120) comprises an electric power output pin (121) configured to be communicated with the built-in power supply (110) so as to output the electric power; and an electric power input pin (122) configured to be communicated with the electric power output pin (121) through external control so as to start the built-in power supply (110) to power the secret key device (100). The data switching apparatus (300) is correspondingly configured to match the secret key device (100) to work, thereby providing a corresponding data interaction component, a data interaction system and a device starting method on the basis of the secret key device (100) and the data switching apparatus (300). |
