Abstract: Disclosed herein are a decoy apparatus and a method for expanding a fake attack surface using a deception network. The method includes determining, by a protected server, whether a packet is a target to be processed when the packet is received; converting, by the protected server, the packet and transmitting, by the protected server, the converted packet to the decoy apparatus of the deception network when the packet is determined not to be such a target; receiving, by the protected server, a response packet from a decoy virtual machine included in the decoy apparatus as a reply to the converted packet; and modifying, by the protected server, the response packet and transmitting, by the protected server, the modified response packet to the source from which the packet was transmitted, in order to expand the fake attack surface.

Abstract: Disclosed herein are a server apparatus, a client apparatus, and a method for communication based on network address mutation. The method for communication based on network address mutation, performed by the server apparatus and the client apparatus, includes setting the external address of a network interface for receiving a packet from the client apparatus; setting the internal address of a hidden interface in order to forward the packet received through the network interface to the hidden interface; modifying the external address based on a preset network address mutation rule; and communicating with the client apparatus by forwarding the packet, received from the client apparatus based on the modified external address, to the hidden interface.

Abstract: Disclosed herein are a network environment synchronization apparatus and method. The network environment synchronization apparatus includes one or more processors, and execution memory for storing at least one program that is executed by the one or more processors, wherein the at least one program is configured to collect data from a network environment and generate a management structure in which collected data is distributed into preset respective group units, generate data discriminators for respective group units using a preset hash function, determine whether data of the management structure has changed with reference to data newly collected from the network environment based on the data discriminators, and when it is determined whether data of the management structure has changed, update the data of the management structure with the newly collected data.

Abstract: Disclosed herein are a reward apparatus and method for blockchain-based blockchain-based Reconfigurable Intelligent Surface (RIS) infrastructure sharing. The reward apparatus for blockchain-based RIS infrastructure sharing may provide a service to a service user terminal through an RIS node, verify a contribution of the RIS node to provision of the service quantified by the RIS node using a first blockchain network, and provide a reward to the RIS node depending on the contribution.
