Question

The key schedule results in generating multiple keys from the one secret key. These multiple keys are used:

Answer 1

Answer:

Option(d) is the correct answer to the given question .

Explanation:

There are various type of algorithm is used for the purpose of the key scheduling such as AES .in the AES algorithm we used same key for encryption and decryption of text .The  main objective of the AES algorithm it is used by Various round of the similar plain text encryption to reinforce the cipher text.

• The Option (a) is wrong because In the key scheduling the creating keys are not being used one after just another in the various communication cycles.

• The Option (b) is wrong because In the key scheduling  we do not used the  the random key for the encryption process .

• The Option (c) is wrong because we will never arbitrarily subdivided into groups of public and private key.
