查询词典 cryptanalyst

This leaves the cryptanalyst with a file that contains only the two original files XORed against each other.

这就只剩下了一个文件，只包含对彼此异或两个原始文件密码分析。

Only a cryptanalyst, if anybody, can judge the security of a cryptosystem.

只有密码分析者才能评判一个密码系统的好坏。

This, like message splitting, does force the cryptanalyst to work on two separately keyed blocks at once, and thus it has some value, but I am not sure of exactly how much value.

这一点，像信息分裂，并迫使cryptanalyst工作，对两个单独键控块一次，因此，它具有一些价值，但我不知道到底有多少价值。

Additionally, the cryptanalyst can use plain text attacks.

此外，密码分析可以使用纯文本攻击。

In these attacks, if the cryptanalyst knows the file type, then he can use knowledge of header formats to guess at the key stream used to encode the file.

在这些袭击中，如果知道密码分析的文件类型，那么他可以使用头格式的知识来猜测用于编码文件的密钥流。

The messages sent in both directions are enciphered random data, impossible to break individually, but now it is also not possible for the cryptanalyst to determine which three messages to attempt to correlate with one another, or at what starting points.

发出的两个方向是加密的随机数据，就不可能打破个别的，但现在它也不可能为cryptanalyst ，以决定哪三个信息，以试图与关联，又或在什么起点。

If a cryptanalyst thinks that a user has used the same key to encrypt two different files, he can XOR the two files together and cancel out the output from the PRNG.

如果密码分析认为，在用户使用相同的密钥来加密两个不同的文件，他可以异或两个文件一起，并取消了从PRNG输出。

We show that unless a cryptanalyst can completely break the RSA encryption ,any heuristic oracle he uses to determine the least significant bit of the cleartext must have an error probability greater than 1/2-ε.

证明了，对于任意用于确定RSA明文的最后一个有效位的启示，必须有大于1/2-ε的出错概率，否则密码分析人员能够完全破译RSA。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
