Question 1

What is the 4th step in DES Algorithm?
A)key transformation
B)s-box substitution
C)p-box permutation
D)expansion permutation

Accepted Answer

The answer of What is the 4th step in DES...

Question 2

In AES in which Round Subkeys are Generated from Original key for each round?
A)key expansion
B)initial round
C)finale round
D)none of these

Accepted Answer

Subkeys for each round in AES are generated from the original key during the key expansion phase. This process involves taking the original key and applying a series of transformations to generate a new set of keys for each round of the encryption process.

Question 3

AES stands for?
A)authorized encryption standard
B)advance encryption standard
C)advance encryption strategy
D)none of these

Accepted Answer

AES stands for Advanced Encryption Standard, which is a symmetric encryption algorithm widely used across the globe to secure data.

Question 4
