公开密钥系统 meaning in English
open key system
public key systems
Examples
- Pkp holds the patents and exclusive licensing rights to all public - key systems on behalf of rsa data security , mit , stanford university , and others
Pkp代表rsa数据安全公司、麻省理工学院、斯坦福大学和其它机构，拥有所有公开密钥系统的专利权和唯一的许可发放权。 - Because , at the bit - length of typical keys , very few numbers are primes , public - key systems must use very large keys to prevent exhaustive searches that try to guess the prime numbers used or to factor the keys
就典型钥匙的位长而言，因为素数的数目是非常少的，故公开密钥系统必须使用非常大的密钥，以防止穷尽研究把使用的素数猜出来或把密钥的因子算出来。 - The agent of kdc according to the picture and individual character information which users input , the base key of producing automatically , make the conversation every side produce the self - same main key , has solved the problem of key distribute ingeniously . and it utilize irreversible hash function produce session key realize one - time key . the thesis has also analysed the application of different situations that the agent of kdc among the conversation modes in many ways
本文提出的个性化kdc代理根据用户输入的图片和个性信息，自动产生基密钥，分别运用公开密钥系统进行交换，使通话各方各自产生完全相同的主密钥，巧妙地解决了密钥分配和加密解密同步的问题，并利用单向散列函数的性质，基于相同的算法产生用于加密解密的一次一密会话密钥。 - Put forward in text that individualized acts as agent to be kinds of simple kdc system , utilize kdc security , can trusting , and some relevant institutional framework , produce and manage the key system according to the individualized information that users offer , session key , public - key and acting for users to converse
本文提出的个性化kdc代理是一种简化了的kdc系统，它是利用kdc系统的安全性、可信赖性，以及一些相关的组织结构，根据用户提供的个性化信息来产生和管理个性化公开密钥系统、个性化会话密钥系统以及代理用户进行通话。 - The thesis depends on cryptography and mathematics , digital watermark , user individual character information hide , public - key and session key ' s production , custody , etc . have analysed about the security of the algorithm , such as attack voluntarily , attack passively , key management
本论文主要运用了计算机密码学及数字图像、数论、数字水印的相关知识，如用户个性信息的隐藏，公开密钥系统和会话密钥系统的生成、保管等。并针对被动攻击、主动攻击、密钥管理、向前和后向保密性对算法的安全性进行了分析。
