  7. The paper discusses the development of web, browser / server mode conception and the content and mechanism of network security based on web, and also describes the basic conception and system of cipher theory, symmetric - based data encryption standard and advanced encryption standard and asymmetric - based rsa. it presents a detailed design of secrecy net of digital government, and advances a des - and - rsa - based security model of information exchange, which makes use of symmetric cryptographic algorithm to encrypt plaintext, and introduces public - key algorithm rsa to encrypt session key to compose digital envelope and to realize digital signature

    本文論述了web的發展及其browser / server模式概念，以及基於web的網路安全的內容與機制；闡述了密碼學的基本概念、分類，對稱密鑰密碼體制des與aes以及公開密鑰密碼體制rsa ；最後，利用一種基於des和rsa的信息交換安全模型，詳細地給出了一個數字政府的保密網系統設計方案。

    分組密碼（ block cipher ）將明文分成塊然後依次加密它們的一種對稱密碼。
  13. A measure of the number of bits in a given key ; note that although increasing the key length gives added security, it s not appropriate to compare the lengths used with one cipher with those in another and, in general, that key lengths in symmetric ciphers do not equate directly with key lengths in asymmetric ciphers

    給定密鑰中位數的度量；注：雖然密鑰長度越長，安全性越強，但將一個密碼使用的長度與另一個的長度進行比較是不合適的，通常，對稱密碼中的密鑰長度與非對稱密碼中的密鑰長度不是直接相等的。
