PURPOSE: A system and a method for controlling entrance and exit are provided to control entrance and exit of a mobile terminal. CONSTITUTION: An entrance/exit management server(50) generates an authentication security key using a card sharing key associated with a smart card electrically connected to a mobile terminal. The entrance/exit management server transmits a one time used card password to the mobile terminal. A reader device(30) primarily authenticates the smart card using the authentication security key and a card security key received from the smart card. If the primary authentication succeeds, the reader device secondarily authenticates the smart card using the one time used card password and a one time used device password. |
