In the research of secure communication, the thesis analyzes some shortcomings of diffie - hellman ' s crypt key exchanging protocol, presenting a new exchanging method based on the " station to station " protocol and cookie mechanism, realizing the software of crypt key exchanging and secure communication of ip datagram on router
在對安全通信的研究中，本文分析了diffie - hellman密鑰交換協議中易受攻擊的地方，提出了基於端對端協議及cookie機制的密鑰交換新方法，並在路由器上實現了密鑰交換和ip報文的安全通信。 -
Transparent model realization built in ip rebuilding, one course of rebuild, check and forward of ip data gram base mac frame and under united structure, and the method to realize stream filter base tcp datagram assorting management and special protocol rebuilding, and tcp datagram rebuilding have nothing to do with application protocol completely transparent for application have some innovations
保留mac地址，同一數據結構下的ip報文重組、檢查、轉發過程一氣呵成，將透明模式融合在ip重建過程中實現；在對tcp報文採取分類處理的指導思想下，通過重建專用tcp來實現流過濾；這些均為本文創新之處。 -
Subnet, in which case the sending host will forward the datagram to a gateway - an ip host that connects two subnets - which will then try to deliver the datagram to the destination host if the destination host is in one of the subnets connected to the gateway
子網，這種情況下發送主機將把數據報轉發到網關（連接兩個子網的ip主機） ，然後，如果目的地主機在一個與網關相連的子網中，則網關會嘗試將數據報傳遞到目的地主機。 -
Ip provides the most basic form of datagram delivery across the boundaries of the underlying physical networks
Ip在底層物理網路的邊界之間提供最基本的數據報傳遞形式。 -
For example, the attacker could send a datagram from host a to host b, but use the ip address of host c in the datagram header s source address field
例如，攻擊者可以從主機a向主機b發送數據報，但在該數據報頭的源地址欄位使用主機c的ip地址。 -
The icmp echo request failed because the destination ip address cannot receive icmp echo requests or should never appear in the destination address field of any ip datagram
由於目標ip地址無法收到icmp回送請求或者永遠都不應當出現在任何ip數據報的目標地址欄位中， icmp回送請求失敗。 -
Class holds the data contained in an ip datagram packet
類保存了ip數據報包中包含的數據。 -
For protecting the safety of ip datagram, ipsec is present the mainstream network layer ' s safe mechanism
對于保護ip數據報的安全而言， ipsec是目前主流的網路層安全機制。 -
Like the ip datagram, the tcp segment consists of a header portion, an optional options section, and the data portion
與ip數據報類似， tcp段包含頭部分、可選（選項）部分和數據部分。 -
The ietf s security additions specifications providing for authentication, integrity, and privacy services at the ip datagram layer
為ip數據報層上的認證、完整性和保密性服務提供的ietf （ tm ）安全性附加規范。 -
Every ip datagram contains a field in its header - called a " time to live field " - which indicates how much longer the datagram is to remain on the internet before it is discarded
每個ip數據報頭中都包含一個欄位稱為「生存時間欄位」它指出數據報在被丟棄之前還能在因特網上保持多久。 -
Section one, we illuminate the conception of multicast. ip multicasting is the transmission of an ip datagram to a " host group ", the datagram is not guaranteed to arrive intact at all members of the destination group or in the same order relative to other datagrams
第一部分介紹組播相關概念。組播是基於udp數據報方式的，非面向連接的一種網路數據發送方式，組播是rtp rtcp數據傳輸的基礎。 -
Finally we analized the aes algorithm and its application in ipsec protocol. ( 2 ) because the communication of ip datagram has charaisteristics of itself, we analized the influence that ip datagram communication does on encryption modes, and put forward some design rules
（ 2 ）加密技術的安全性不但和演算法有關，而且和密碼模式也有關，一種模式在這個環境中是安全的，在另外一個環境可能容易受到攻擊。 -
Designed as a replacement of udp, wdp provides the same wap datagram service interface as udp. it can use the short message platform when there is no ip traffic
Wdp設計為udp的替代，像udp一樣提供相同的wap數據報服務介面，它在下層沒有ip承載時可使用簡訊平臺。 -
If the gateway processing a datagram determines that the time to live field in the datagram s ip header is 0, it discards the datagram and notifies the sending host with a
如果處理數據報的網關測定該數據報ip頭中的生存時間欄位為0 ，則丟棄該數據報並用 -
However, ip multicast make use of udp protocol to deliver datagram on the transport layer, which only provides a " best effort delivery " service, so this protocol ca n ' t sure the reliability of data transmission
然而ip多播使用的傳輸層協議是udp協議，提供的數據傳輸只是「盡力交付」 ，不能保證數據傳輸的可靠性。
