Question

Rail fence cipher is more secure than one time pad cipher.

(a) True

(b) False

This question was posed to me at a job interview.

I need to ask this question from Cryptography topic in division Cryptography of Data Structures & Algorithms II

Answer 1

Correct option is (b) False

Best explanation: One time pad cipher is one of the most secure traditional cipher as it is almost impossible to crack. Rail fence cipher is not very hard to crack. Thus rail fence cipher is less secure than one time pad cipher.
