论文摘要
我们考虑了通过嘈杂的多路径网络安全可靠的通信问题。以前的工作考虑了我们问题的无声版本，提出了混合通用网络编码加密系统（HUNCC）。通过将信息从理论上的安全编码器与部分加密结合在一起，Huncc即使在有全面的窃听器的情况下，Huncc也能够获得安全保证。在本文中，我们提出了HUNCC的嘈杂频道（N-Huncc）的版本。这种修改需要四个主要新颖性。首先，我们提出一个网络编码构建，该构建具有共同的，单独的安全和错误纠正。其次，我们介绍了一个新的安全定义，该定义是个人安全性的计算类似物，我们称其为单独的Ciphertext攻击（单个Ind-CCA1），并表明NHUNCC满足了它。第三，我们提出了基于噪声的解码器，该解码器允许解码编码的thenencypted数据。最后，我们讨论如何选择N-Huncc及其错误校正功能的参数。
We consider the problem of secure and reliable communication over a noisy multipath network. Previous work considering a noiseless version of our problem proposed a hybrid universal network coding cryptosystem (HUNCC). By combining an information-theoretically secure encoder together with partial encryption, HUNCC is able to obtain security guarantees, even in the presence of an all-observing eavesdropper. In this paper, we propose a version of HUNCC for noisy channels (N-HUNCC). This modification requires four main novelties. First, we present a network coding construction which is jointly, individually secure and error-correcting. Second, we introduce a new security definition which is a computational analogue of individual security, which we call individual indistinguishability under chosen ciphertext attack (individual IND-CCA1), and show that NHUNCC satisfies it. Third, we present a noise based decoder for N-HUNCC, which permits the decoding of the encoded-thenencrypted data. Finally, we discuss how to select parameters for N-HUNCC and its error-correcting capabilities.
