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.
