Cipher message database on financial management system based on this dissertation is an important sub - system of financial management system. it ' s of simple construction, and implement method is convenience. resolving the security problem of financial information, and it worth some reference value to developing database security and secret system in mis
基於本文設計的財政密文數據庫系統是財政管理系統的一個重要子系統，結構簡單，實現方便，解決了財政信息的安全問題，對在mis中開發數據庫安全保密系統具有一定的參考價值。 -
As regards cryptographic algorithm, according to database encryption requirement for cryptosystem, we adopt block cipher, which is high intensity and fast, based on analysing and comparing several popular cryptographic algorithm ; and resolve cipher message expansion problem through making improvement of block cipher with " cipher message whmovement "
在數據的加密演算法上，本文在分析比較目前常用的加密演算法的基礎上，依據數據庫加密對密碼系統的要求，採用了保密強度大且速度快的分組密碼；並用「密文挪用法」對分組密碼進行改進，解決了加密后數據擴張的問題。 -
Macs. 1 : information technology - security techniques - message authentication codes - part 1 : mechanisms using a block cipher
信息技術.安全技術.文電鑒別碼 -
The first key technique : using plain - text cipher and md5 message - digest algorithm to ensure stb and dhcp server ' s certificate and secure the stb and server ' s communications - the second key technique : using hmac algorithm to realize the safe functions - the third key technique : using ipsec to realize safe functions o those three methods " complexity increases in turn and the degree of the security increases as well which depend on the frame of the methods and the complexity of the algorithm. all theose three methods use the unique serial - number or a special slip - window to defend replay attack
主要採用三種安全方案實現：第一種：利用約定的明文密碼驗證機頂盒與dhcp服務器的合法身份， md5驗證信息合法性：第二種：利用hmac演算法驗證機頂盒與服務器身份，信息合法性；第三種：利用ipsec驗證機頂盒與dhcp服務器身份與信息合法性。每一種方案中皆採用包序號唯一法或者滑動窗口法保證重放攻擊。此三種方案復雜度依次增加，安全度依次升高，主要取決于演算法的復雜度與架構的搭建。 -
In cryptography, the additional characters added to a plaintext message, to ensure that its length is an integral number of blocks for encryption by a block cipher
在密碼學中，為了使明文信息的長度為分組密碼加密中所用的塊的整數倍，而在明文中添加的附加字元。 -
They wanted to issue a series of strong security cipher standards, including not only block cipher, but also stream cipher, hash function, message authentication code, digital signature, public key cipher and so on
緊接著， 2001年1月，歐洲啟動了規模更大的nessie工程，希望推出一套不僅包括分組密碼，還包括流密碼、 hash函數、消息認證碼、數字簽名和公鑰加密等在內的強安全性的密碼標準。 -
Also known as the vernam cipher and considered unbreakable although not easy to manage ; the key consists of a random selection of bits exactly as long as the message itself and with which it is xored
也稱為vernam密碼，它雖然難以管理卻被認為是不可破解的；密鑰由完全與消息本身等長的隨機選擇的位構成，並將它與消息進行xor運算進行加密。 -
Finally, the result is xored with the cipher text to reveal the message
最後，將結果與密文進行xor運算，以顯示消息。
