 note = {無線通信における盗聴対策として,陸上移動通信におけるビット誤り率変動に基づく秘密鍵共有方式を提案する.提案方式では,正規局間における秘密鍵生成の共有情報として,ビット誤り率を用いて秘密鍵を生成する.ビット誤り率を用いることで,伝搬路における振幅位相変動などの劣化要因に基づいた秘密鍵を生成し,共有することが可能となる.提案方式の有効性を確認するため,無線LANを想定したモデルを用いてシミュレーションを行ったところ,信号電力対雑音電力比15dB以上の環境で秘密鍵の一致が可能であり,提案方式の有効性が確認できた., This paper proposes a private key agreement scheme using the fluctuations of BER (Bit Error Rate). In the proposed scheme, the received BER at both authorized users is used as the common information for key generation between them. BER is an appropriate indicator to characterize the wireless channel because it includes all factors to generate bit errors such as fluctuations of amplitude and phase, effect of delayed waves etc. In order to evaluate the performance of the proposed scheme, numerical simulations are carried out assuming the configurations and the parameters of wireless LAN system. The results of the simulations show that the proposed scheme successfully achieves the key agreement at SN ratio of 15dB when it is combined with data deletion and error correction schemes., application/pdf},
