例句與造句

  1. Frequency analysis is the basic tool for breaking most classical ciphers.
  2. The method is used as an aid to breaking classical ciphers.
  3. Classical ciphers are typically vulnerable to known-plaintext attack.
  4. Some techniques from classical ciphers can be used to strengthen modern ciphers.
  5. CrypTool contains the most classical ciphers as well as modern symmetric and MSS ) are visualized.
  6. It's difficult to find classical ciphers in a sentence. 用classical ciphers造句挺難的
  7. Such classical ciphers still enjoy popularity today, though mostly as puzzles ( see cryptogram ).
  8. Like most classical ciphers, the Playfair cipher can be easily cracked if there is enough text.
  9. Classical ciphers do not satisfy these much stronger criteria and hence are no longer of interest for serious applications.
  10. Many of the classical ciphers, with the exception of the one-time pad, can be cracked using brute force.
  11. Ciphertexts produced by a classical cipher ( and some modern ciphers ) will reveal statistical information about the plaintext, and that information can often be used to break the cipher.
  12. Furthermore, computers allowed for the encryption of any kind of data representable in any binary format, unlike classical ciphers which only encrypted written language texts; this was new and significant.
  13. If a linear congruential generator is seeded with a character and then iterated once, the result is a simple classical cipher called an affine cipher; this cipher is easily broken by standard frequency analysis.
  14. Many classical ciphers arrange the plaintext into particular patterns ( e . g ., squares, rectangles, etc . ) and if the plaintext doesn't exactly fit, it is often necessary to supply additional letters to fill out the pattern.
  15. Nonetheless, good modern ciphers have stayed ahead of cryptanalysis; it is typically the case that use of a quality cipher is very efficient ( i . e ., fast and requiring few resources, such as memory or CPU capability ), while breaking it requires an effort many orders of magnitude larger, and vastly larger than that required for any classical cipher, making cryptanalysis so inefficient and impractical as to be effectively impossible.
