Data encryption standard cipher block chaining packet encryption
數據加密標準密碼分組鏈接分組加密 -
It includes chip selection, schematic circuit design, cpu selection and configuration, startup of the system, selection and configuration of embedded operation system, selection and configuration of tcp / ip software. it also describes some driver programming techniques of network controller. part 3 ( chapter 5 and 6 ) briefly introduces encryption technology and the ipsec protocol system, including architecture, mode, security association, security policy, implementation mode, processing of in / out packet, esp ( encapsulation security payload ), ah ( authentication header ), ike ( internet key exchange ) etc. the security requirements of embedded - networking is also analyzed
本文首先探討了嵌入式網路的原理和設計要求，接著介紹了本文所開發的嵌入式系統的硬體平臺的設計（包括處理器的選擇與配置、存儲器的選擇和io設備的選用等） ，系統的啟動（包括bios和dos的啟動以及嵌入式操作系統vrtx的配置和引導） ，網路及其安全服務的實現（包括嵌入式協議棧usnet的選取、底層驅動程序的設計和安全協議ipsec的分析與實施） 。 -
Because packet encryption devices do not require a one - to - one relationship with the links or circuits they encrypt, network managers can more readily implement redundant devices to avoid a single point of failure
由於包加密裝置不需要與它們加密的鏈路或線路有一對一的關系，所以網路管理員可以更容易地設置冗餘裝置，以避免單一點的失效。 -
The globalization of business also should boost the popularity of packet encryption because it allows a variety of different algorithms to be used for domestic and offshore links
業務的全球化也應加快包加密的流行，因為包加密允許使用各種不同的演算法用於國內和海外的鏈路。 -
Unlike link encryption, where one key is applied to all data traversing a given connection, packet encryption allows keys to be applied selectively to designated packets
與鏈路加密不同，一個密鑰加在了給定連接上通過的所有數據，而包加密可使多個密鑰有選擇地加在指定的包上。 -
As corporations depend more on increasingly dynamic networks - - and as it becomes more critical to protect the data traversing those networks - - packet encryption likely will become an important tool in corporate security strategies
隨著各公司越來越多地依賴于動態網? ?以及隨著保護跨越這些網路的數據變得更為緊要，包加密很可能成為公司安全策略中的重要工具。 -
Functioning at the network layer of the open systems interconnection model, the packet - encryption device at the originating site encrypts the entire packet, including the ip header, and provides it with a new header
由於是在「開放系統互連」模型的網路層上起作用的，始發站上的包加密裝置對整個包加密，包括ip報頭，都提供一個擁有新報頭的包。 -
Firstly, it narrates processing of in / out packet, constructing spd ( security policy database ) and sadb ( security association database ), studying ike, realizing the module of encryption algorithm by modifying usnet. secondly, it introduces some ways to improve the capability of the whole system that has implemented ipsec
最後作者論述了自己對系統為實施安全協議所做的調整與優化；同時筆者也對進一步提高系統的可靠性和實時性提出了自己的建議，並在操作系統與協議棧的無縫連接方面進行了初步探討。 -
Decryption generates the identical keystream used for encryption using the transmitted - with - the - packet iv and the shared secret key
解密通過使用帶信息包傳輸的iv和共享密鑰來生成用於加密的等同密鑰流。 -
Freedom from synchronization issues also is important in case of dropped connections. while intermittent network problems can seriously disrupt link encryption, packet - encryption devices can tolerate temporary signal loss
萬一連接中斷時，不依賴于同步的問題也是很重要，間歇性的網路問題可以嚴重地破壞鏈路加密，而包加密裝置可以容忍暫時的信號丟失。
