    Abstract: An attack analysis device includes: an obtainer that obtains in-vehicle network information indicating a configuration of an in-vehicle network including a plurality of external communication interfaces and a plurality of control Electronic Control Units (ECUs), and anomaly detection information indicating a result of detecting an anomaly in at least one node in the in-vehicle network; an attack path estimator that, based on the in-vehicle network information and the anomaly detection information, estimates an attack path in an attack on the in-vehicle network, the attack path including an entry point indicating an external communication interface that is a point of intrusion into the in-vehicle network in the attack and an attack target indicating a control ECU that is a target of the attack; and an outputter that outputs the attack path.

    Abstract: A reception device includes: a receiver that receives a multiplexed signal; a first demapper that demaps the multiplexed signal, with a second modulated symbol stream being included in the multiplexed signal as an undetermined signal component, to generate a first bit likelihood stream; a second demapper that demaps the multiplexed signal, with a first modulated symbol stream being included in the multiplexed signal as an undetermined signal component, to generate a second bit likelihood stream; a first decoder that performs error control decoding on the first bit likelihood stream; and a second decoder that performs error control decoding on the second bit likelihood stream. The multiplexed signal is a signal on which the first modulated symbol stream and the second modulated symbol stream are superposed, the second modulated symbol stream being subjected to conversion in accordance with the first modulated symbol stream in only a first direction.
