Abstract: An electronic device and a control method thereof are provided. The electronic device includes a memory configured to include a non-secure region operating in a normal world and a secure region operating in a secure world, and a processor configured to selectively operate in one of the normal world and the secure world, check integrity of a plurality of code blocks loaded on a first area of the non-secure region while operating in the secure world, and when one of the plurality of code blocks is compromised, change a memory region corresponding to a compromised code block to a secure region, and load an original code block of the compromised code block on a second area of the non-secure region.

Abstract: A security network system is disclosed. The security network system includes a processor selectively operable in either a normal world or a secure world, wherein the processor receives, from an external network, a packet by using a network driver module of the secure world, extracts data of the packet by using a TCP/IP module of the secure world if the packet received from the external network is used in the secure world, uses the data of the packet in the secure world, and extracts the data of the packet by using the TCP/IP module of the secure world so as to transmit the data of the packet to the normal world if the packet is not used in the secure world.

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.
