In AES Key expansion, if w19 = 54010FFA, what is t20?

In AES SubBytes, What is the value for 4E?

For p = 11 and q = 19 and choose e=17. Apply RSA algorithm where message=5 and find the cipher text.

In Elgamal cryptosystem, given the prime p=31. Choose e1= first primitive root of p and d=10, calculate e2.

Sender chooses p = 107, e1 = 2, d = 67, and the random integer is r=45. Find the plaintext to be transmitted if the ciphertext is (28,9).

Which of the following keys are known only to the owner?

• public key

• protected key

• private key

• unique key

• True

• False

In Diffie-Hellman, Alice and Bob agree on p = 23 and g = 5. Alice chooses a = 6 and sends public key. What is the value of the public key?
