Abstract: The analysis unit generates one or more pairs of a start point fact which is a fact representing possibility of attack in a device that is a start point and an end point fact which is a fact representing possibility of attack in a device that is an end point. The analysis unit analyzes, for each pair, whether or not it is possible to derive the end point fact from the start point fact. The analysis unit generates an attack pattern that includes at least an attack condition, an attack result, and an attack means, in a case where it is possible to derive the end point fact from the start point fact.

Abstract: Provided are a communication terminal device and the like that enable efficient transmission and reception of information among a plurality of communication terminal devices, even in an environment with no communication management device that manages and controls the communication terminal devices in a centralized manner. The communication terminal device includes a reception control unit for determining a reception port number on the basis of a first identifier that can identify a first application; a filtering unit for setting the reception port number as a reception port number for the first application; and a transmission control unit for determining, on the basis of a second identifier that can identify a second application, a destination port number indicating a destination in a specific communication terminal device.

Abstract: A node device has a delivery predictability management part, a DTN communication part, and a user interface part. The delivery predictability management part stores, for each destination node, delivery predictabilities including a delivery predictability for the destination node calculated by a local node and a delivery predictability for the destination node calculated by a neighboring node. The DTN communication part refers to the delivery predictabilities for each destination node and selects a next hop node in transferring transfer data from the local node to the destination node. The user interface part allows selection of a destination node for DTN communication with the local node as a source node on a basis of the delivery predictabilities for each destination node.
