In the traditional cryptography , there is one sender , one receiver and an active or a passive eavesdropper who is an opponent 在传统保密通信中，有一个发送方、一个接收方和一个敌方，敌方可能是主动攻击者也可能是被动窃听者。
Trouble is , the design of wep allows eavesdroppers to decode the wep - encrypted messages fairly simply , and thus gain access to networks and data 问题是， wep的设计使窃听者能够相当简单地译码wep加密的消息，从而获得对网络和数据的访问。
To help protect the data transferred between clients and servers from eavesdroppers , you should encrypt it by using digital certificate technology 为了帮助保护客户端和服务器之间传输的数据免于被窃听者窃取，您应该使用数字证书技术对数据进行加密。
So sure was salomon that rivals were out to nab its trading secrets that it had the curtains of its boardroom treated to shield it from electronic eavesdroppers 萨洛蒙如此安全可靠，极力保守他的交易秘密，以至于他们的会议室的窗帘被处理成屏蔽电子窃听器的。
Heisenberg " s uncertainty principle guarantees that no eavesdropper can escape detection because of the fact that the eavesdropper cannot measure the signals without disturbing them 根据海森堡测不准原理，任何窃听者无法窃听量子密码通信中的信息而不被发现。
Otherwise , a malicious eavesdropper on any router between your server and the end user can very easily sniff the sensitive information out of the network packets 否则，恶意的监听者就可以在你的应用程序与最终用户之间的任何路由器上通过数据包探嗅到那些敏感的信息。
At last , a maximum disturbance bound is derived for a given mean photon number and transmission length . eavesdropper can be detected with the bound . 2 采用了分束与breidbart基相结合的窃听策略讨论了窃听问题并给出了合法用户在筛选后的密钥中所能容忍的误码率上限公式。
The information gained by the eavesdropper through interception is a very important criterion for judging the success of the key transmission and a necessary parameter for the privacy amplification 窃听者通过窃听所获取的信息量是决定密钥传输是否成功的重要指标，同时也是保密增强这一技术环节的必要参数。
Natasha blushed at these recollections , and tried as it were to excuse herself , as though there were something to be ashamed of in the emotion to which prince andrey had unwittingly played the eavesdropper 一提起这些往事，她满面通红，极力地为她自己的举动辩护，在安德烈公爵意识到他无意中偷听了她的话时，心中仿佛有点儿不好意思。
