Countering Eavesdroppers with Meta-learning-based Cooperative Ambient Backscatter Communications
, 2023 This article introduces a novel lightweight framework using ambient backscattering communications to counter eavesdroppers. In particular, our framework divides an original message into two parts: (i) the active-transmit message transmitted by the ...

Improvement of anti-eavesdropping performance of spatially selective modulation by transmitting antenna selection [PDF]
空間選択性変調方式(SSM)の盗聴耐性の改善について検討する。SSMはマルチパスフェージングチャネルの可逆性と場所依存性を利用することで、盗聴局での受信を回避し、正規受信局にのみ秘密情報送信を実現する。本論文では、SSMの盗聴耐性を向上させるために送信アンテナのランダム選択を提案する。本方式では、複数の送信アンテナをランダムに選択し、その組み合わせを時間的に変化させる。本方式は、常に正規受信局と相関の高いチャネルを有する盗聴局位置の発生を抑制する ...

Auditory risk recognition is socially transmitted across territory borders in wild birds
Animal CognitionPrey species commonly assess predation risk based on acoustic signals, such as predator vocalizations or heterospecific alarm calls. The resulting risk-sensitive decision-making affects not only the behavior and life-history of individual prey, but also ...
