Cryptography 面试题与答案

问题 26. What do you mean by DNA computing?

It is nothing but a collection of random strands of DNA that can be combined to find the solution to a specific problem.

It works perfectly on both basic and as well as large-scale strands.

The other name of DNA computing is Molecular computing. By parallel search, it aims to solve some of the very complex problems that can declare their presence in the cryptography approach.

问题 27. When will you use a shrinking generator in Cryptography?

When a direct interaction is required in the outputs of Linear Feedback Shift Registers, this can be used.

It is actually scalable up to a great extent and has excellent securing properties that make it a good approach to trust.

The shrinking generator can also be used to analyze how to secure information is. It can also be used to imposing a limit on the size of data that needs to be controlled.

问题 28. What do you know about the Vernam Chipper?

In case the bits are generated randomly, this is the chipper that is used for controlling their actions.

It combines them with plain text reliably and the output is regarded as hypertext. Thus a very secure environment can be assured and the best part is it’s not very difficult to use this approach.

问题 29. What do you know about a Compression Function in Cryptography?

It is basically an approach that is used for securing the information reliably.

A Compression function takes input in the form of a fixed length of bits and the outcome is shorter. A method is generally divided into smaller blocks for its easy authentication and implementation in the cycle. Each small block is then processed and the output is the combination of bits and hash value.

问题 30. Is it possible to combine cryptography with any other data security approach?

Yes, it’s possible to do so.
