Question

The CTR mode uses a Key K and an Initial Vector V. The Intel Digital Random Number generator has these values initially as

(a) K = 0 ; V = 1

(b) K = 0 ; V = 0

(c) K = 1 ; V = 1

(d) K = 1 ; V = 0

The question was posed to me in an interview for internship.

I would like to ask this question from Pseudorandom Number Generators and Stream Ciphers in portion Pseudorandom Number Generation and Stream Ciphers and More Block Ciphers of Cryptograph & Network Security

Answer 1

Correct choice is (b) K = 0 ; V = 0

Explanation: K = 0 ; V = 0 for Intel Digital Random Number generator. (Initial Values)
