Route Cipher Multiple Choice Questions and Answers

This set of Data Structures & Algorithms Multiple Choice Questions & Answers (MCQs) focuses on “Route Cipher”.

1. What is route cipher?
a) a transposition cipher that performs encryption by following an imaginary pattern on a grid
b) a substitution cipher that performs encryption by following an imaginary pattern on a grid
c) a transposition cipher that performs encryption by following a zig zag pattern on a grid
d) a substitution cipher that performs encryption by following a zig zag pattern on a grid

Answer: a
Explanation: Route cipher is a transposition cipher. It encrypts the plain text by following an imaginary pattern on a grid. This pattern can vary from one version of route cipher to others.

2. Route cipher is an example of ____________
a) mono-alphabetic cipher
b) poly-alphabetic cipher
c) transposition cipher
d) additive cipher

Answer: c
Explanation: Route cipher is a transposition cipher. It falls under the category of transposition cipher as it encrypts the plain text by rearranging its letters.

3. Encryption in Route cipher is done ___________
a) by arranging the letters in a zig zag fashion in a table
b) by randomly arranging letters
c) by following an imaginary pattern drawn on a grid
d) by swapping adjacent letters

Answer: c
Explanation: Route cipher is a transposition cipher. It encrypts the plain text by following an imaginary pattern on a grid.

4. Which of the following ciphers are created by shuffling the letters of a word?
a) playfair cipher
b) route cipher
c) vigenere cipher
d) hill cipher

Answer: b
Explanation: In transposition cipher the letters of the given data are shuffled in a particular order, fixed by a given rule. Route cipher is the only transposition cipher out of the given options.
