<p>The present invention relates to user equipment, a locking method thereof, and a secure service system supporting the same, which make the cancellation of a locking function difficult by using an isolation structure of the user equipment in which a non-security area operated by a non-security operating system is physically separated from a security area operated by a security operating system. When the user equipment having the isolation structure where the security area and the non-security area are physically separated from each other sequentially performs booting of the security operating system and the non-security operating system, the user equipment activates a security locking mode operated on the basis of the security operating system while booting the security operating system to request an input of unlocking information to a user, and cancels the security locking mode according to the input unlocking information.</p> |
