Exercise 4

More Practice of Encryption Using Transposition

1. Using the shared secret PRIVACY, encrypt the following message with the transposition method:

ANYONE CAN HIDE MESSAGES

2. What result did you get?

Step 1 of 3

Creating cipher text using Transposition method

1. Transposition is a method of encryption wherein a plaintext is converted into a cipher text. This makes the data to be sent more secure as data in encrypted form is difficult to read and understand. Also it is hard to decode.

In transposition method, the basic idea is to rearrange the letters of the word (data) in some different order such that it becomes unreadable.

Given the keyword PRIVACY, the message "ANYONE CAN HIDE MESSAGES", needs to be encrypted using Transposition method.
