查询词典 ciphertext

The method of DPA may attack on encrypted FPGA effectively,which does not need complex analysis to encryption arithmetic and obtains ciphertext and information.

差分功率分析方法可有效地对加密的集成电路芯片进行攻击解密，它绕过了加解密算法繁琐的数学分析，从而获取密码和信息。

Present a decipherable ciphertext attack on the optimized NTRU public key cryptosystem, and conclude that there is possibility that partial information leakage of the secret key will happen when we choose N=503 in the parameter advised in optimized NTRU version.

针对于NTRU 改进算法，给出了一种新的可解密密文攻击，当参数N=503时可能会泄漏部分私钥信息； 2。

By introducing the selective identity and selective chosen message attack model, this paper proved unforgeability of the scheme under the hardness of DHI problem and its indistinguishability against selective identity and chosen ciphertext attack under the hardness of DBDHE problem.

通过引入了选择身份和选择消息攻击的安全模型，利用DHI问题的困难性，证明了方案的不可伪造性，同时利用DBDHE问题的困难性，证明了方案在选择身份和选择密文攻击下的不可区分性。

课内教学活动深入理解可证明安全的基本思想和原理，灵活使用可证明安全的方法和工具分析典型的密码方案，培养和锻炼严密的逻辑思维能力和书面表达能力；流利的口头讲解能力和学术辩论能力；强烈的探索创新能力和团队合作能力。

We also prove that the new scheme is not only indistinguishable against chosen-ciphertext attacks but also existentially unforgeable against chosen-message attacks.

可证明新方案在选择密文攻击下不可区分，在选择消息攻击下存在不可伪造。

The proposed scheme was proven secure against indistinguishably in adaptively chosen ciphertext and identity under the decision q-TBDHE assumption.

在判定性：q-TBDHE假设下，证明了所提方案在适应性选择密文和身份攻击下是不可区分的。

Later, figuratively at midnight, the attacker gains access to the unattended terminal and inputs to it the recorded host-terminal traffic, thus masquerading as the host to the terminal. The terminal deciphers the recorded ciphertext,using the recorded encrypted session key.

话路中的内容包括由终端密钥加密的话路密钥，然后，形象的说法是在午夜，窍密者登录到无人注意的终端，将记录下的主机-终端信息流输入给它，冒充是主机输给终端的，终端用记录下的加密的话密钥将记录的密文解密。

The design in the mail client use RSA encryption algorithm on the message content of asymmetric cryptography, causing E-mails in the transmission process are replaced by ciphertext, ensuring the users are not wiretapped by third-part when using the mail client to communicate with others.

本设计在邮件客户端使用 RSA 加密算法对邮件内容进行非对称加密，这样邮件在传输过程中便以密文代替明文显示，保证用户在使用本邮件客户端与他人通信时不被第三方窃听。

First of all, the structure from the message, the message is divided into 3 parts: the first message, at the style, MAC address, so that packet transmission to reach the safety of the international financial sector standards; Secondly, the encryption method from the point of view, this The most prominent of the two systems were encrypted administrator password is encrypted on the card to encrypt passwords, especially for card encryption, the use of soft encryption service interface technology, using the work key, master key, the original password through the ciphertext key algorithm through two different DES encryption key to come up, we can imagine, I want to work at the same time key, master key, the text of the original secret password to a more difficult task, If the re-solution of the two DES, can be said to be completely impossible!

首先从报文结构上来看，报文分为3部分：报文头、报文体、MAC地址，使报文传输的安全性达到了国际金融行业的标准；其次，从加密方式来看，本次系统最突出的两个加密分别是对管理员密码进行加密、对卡密码进行加密，特别是对卡密码的加密，运用的是软加密服务接口技术，运用工作密钥，主密钥，原始密码通过算法得到密钥密文通过两次不同的DES加密才得出的密钥，可想而知，想要同时得到我的工作密钥，主密钥，原始密码密文本来就比较困难了，要是再解两次DES，可以说是完全不可能实现的！

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
