摘　　要：论述了嵌入式安全网卡的结构、功能,分析了网络监听原理、检测手段和防范措施,提出了把嵌入式安全网卡应用到网络监听中的方案。在嵌入式安全网卡中有一个重要部件加密机,它能采用不同加解密算法对数据进行加解密,还能解决加密运算的瓶颈。安装了这种网卡的电脑,在进行数据传输中,即使通信内容被监听到,所得到的也是被加了密的内容,不能被破译,从而实现了数据在网络传输过程中的安全。This paper discusses the structure and function of embedded sate network card and analyses the principle, the detecting methods and defending measures of network sniffing. It proposes a scheme about putting embedded safe network card to network sniffing. There is an encryptor which is important part in the embedded safe network card. It can encrypt data and decrypt data through different encrypt algorithms and decrypt algorithms, and it can settle the bottleneck of encrypted operation. When the computer that is set such network card transfer data, the data which are sniffed are encrypted. It realizes the security of data in the course of network transmission.
