在无线网络中，攻击者可以调整接收器并窃取两个节点之间的通信。是否通过无线连接获得一些有意义的信息取决于传输方案。本文将信息论方法与密码学方法相结合，设计了一些安全的网络编码。它保证了无论窃听多少条信道，窃听者都无法获得任何有意义的信息。此外，如果在每个源数据包中增加一个哈希符号，该哈希符号是由数据符号的简单非线性多项式函数计算得到的，那么检测到修改的概率就很高。
In wireless networks, an attacker can tune a receiver and tap the communication between two nodes. Whether or not some meaningful information is obtained by tapping a wireless connection depends on the transmission scheme. In this paper, we design some secure network coding by combining information-theoretic approaches with cryptographic approaches. It ensures that the wiretapper cannot get any meaningful information no matter how many channels are wiretapped. In addition, if each source packet is augmented with a hash symbol which is computed from a simple nonlinear polynomial function of the data symbols, then the probability of detecting the modification is very high.
