Question

Gronsfeld cipher is similar to?

(a) additive cipher

(b) multiplicative cipher

(c) caesar cipher

(d) affine cipher

The question was posed to me in examination.

My question is from Cryptography topic in section Cryptography of Data Structures & Algorithms II

Answer 1

Correct answer is (c) caesar cipher

Easy explanation - In gronsfeld cipher we shift the letters of the plain text on the basis of the key value. So it becomes a modified version of the caesar cipher.
