ipsec services 中文意思是什麼
-
Then the second chapter researches the principle of the ipsec, which provide security services through ah and esp protocols. both ah and esp can work under two working mode : transferring mode and tunnel mode
Ipsec主要通過ah和esp來提供安全服務， ah和esp又分別可以工作在傳輸模式或隧道模式下，通過不同的配置可以滿足不同的安全需求。 -
Ipsec offers security services including connectionless integrity, data origin authentication, protection against replays, confidentiality and limited traffic flow confidentiality for ip and upper layer protocols
Ipsec為ip及上層協議提供了無連接完整性、數據源身份認證、抗重播攻擊、數據內容的機密性和有限的通信流量機密性等安全服務。 -
Fortunately, ipsec provides us security services for ip layer and higher layers, such as access control, connectionless integrity, data origin authentication, rejection of replayed packets ( a form of partial sequence integrity ), confidentiality ( encryption ), limited traffic flow confidentiality, and so on. the thesis gives a type of network security architecture based on ipsec system, it includes the following contents : 1 analyzing the security problem in tcp / ip protocol stack, current main network attack methods and regular defense methods. 2 studing the overall architecture, main security protocols, application environments, and working mechanism of ipsec
本文所提出的新一代網路安全體制就是建立在ipsec體系基礎上的，在本文的撰寫過程中，我主要進行了如下一些工作： 1深入分析了由tcp ip協議棧本身帶來的安全問題、當前主要的網路攻擊方法以及常採用的防範對策； 2研究了ipsec標準的總體結構、主要安全協議、應用場合以及其工作機制； 3研究了當前常用的各種數據加解密機制以及密碼演算法，深入分析了它們各自的特性和具體的使用方式； 4閱讀了大量關于混沌密碼的文獻資料，了解目前混沌密碼的研究動態和成果，研究混沌密碼體制的工作機理，然後利用vc + + 6 . 0作為開發平臺對一類混沌密碼體制進行了實現，並為它編寫測試代碼評估其性能。 -
In tcp / ip protocol suite, the ipsec protocol provide interoperable, high quality, cryptographically - based security for ipv4 and ipv6. the set of security services offered includes access control, connectionless integrity, data origin authentication, protection against replays ( a form of partial sequence integrity ), confidentiality ( encryption ), and limited traffic flow confidentiality
在tcp ip協議族中， ipsec （ internetprotocolsecurity ）協議提供的安全服務保證數據在網路傳輸過程中的機密性、完整性和抗重放保護，以及對網路通信中的通信流分析攻擊提供有限的保護， ipsec協議還提供對網路的訪問控制能力。 -
Ipsec provides these security services at the ip layer. it protects and authenticates ip packets transferring between ipsec devices
其目標是為ipv4和ipv6提供具有較強的互操作能力、高質量和基於密碼的安全。
