Abstract: Provided are an electronic apparatus in which a normal operating system (OS) and a secure OS are installed and a method for controlling the electronic apparatus. The method for controlling the electronic apparatus includes searching for at least one external terminal in which a secure OS is installed, selecting a first terminal from among the at least one external terminal in which a secure OS is installed, in response to a first terminal being selected from the retrieved at least one external terminal, performing communication connection with the first terminal, searching for at least one terminal in which only a normal OS is installed, from among at least one external terminal that is capable of being communication-connected to the first terminal, and performing communication with a second terminal of the at least one terminal in which only the normal OS is installed, through the first terminal.
