Cryptography вопросы и ответы для интервью

Вопрос 16. What is the One-Way function?

One-Way function is basically an approach that is used to assure faster information processing for cryptography when data needs to be sent in one way only and no reverse action is possible.

Functions can be computed in one direction within a very short span of time but performing the opposite task can be extremely daunting.

Вопрос 17. What exactly is the other name of Checksum in Cryptography?

It is called a Message Authentication Code or MAC.

It can be categorized as block chipper based, unconditionally secure, stream cipher based, as well as hash function based.

Вопрос 18. What is Quantum Cryptography?

When it comes to exchanging secure information over an insecure channel, this approach is considered.

It all depends on the nature of photons in which the third polarization is focused. It can easily be trusted when it comes to exchanging the Secret keys without facing any issue.

Quantum Cryptography is useful when an organization has to send information outside its network without compromising its security and authenticity. It is having a lot of applications in secret and defense operations.

Вопрос 19. Is Cryptography a legal approach or not?

Cryptography is basically an approach that is used for data security.

However, it has been seen that it can also have a lot of cons associated with it. Only governmental agencies and authorized organizations are allowed to use it in some parts of the world and thus it is not accepted as a legal approach everywhere.

Вопрос 20. What is the basic principle of Cryptography?

The basic principle of this approach is nothing but to write and solve codes so that information security can be enhanced and that automatically leads to privacy.
