Cryptology, Binary and ASCII codes Graded Lab

First, each student will pretend that he/she has been involved in some criminal activity and the goal would be to hide some information.

Each student will choose the sentence that consists of 3 words. This sentence should be encrypted or/and encoded so it would be difficult to get information.

To encrypt and/or encode the sentence, you can use all ciphers and codes that we learned so far.

Be creative! You can use a series of chiphers and codes. You can combine ASCII and Binary coding with the ciphers we learned so far.

For example, if my original word is dog

First, I can encrypt it using Caesar Cipher and the result will be GRJ and after that I will encrypt GRJ using Polybius cipher and the final ciphertext will be : 224224
To decrypt, first I would need to use Polybius cipher to get GRJ and after that Caesar Cipher to get an original text dog

After the encryption/coding is done, students will exchange information (the same way we did it for the previous lab).

At that point, you will pretend that you are forensic specialist and you would need to find the original message.

We will limit the amount of ciphers/codes that you can use for encryption to 3.

Grading Requirements:

The sentence must have 3 words
Each word must be encrypted in different way.
Each word must be encrypted using at least 2 different ciphers/codes
You have to use ALL ciphers and codes that we learned so far: Binary, ASCII, Caesar, Shift and Polybius
Each student should document the encryption and decryption process on the paper.
You can use computer to do encryption/decryption and encoding/decoding, BUT you have to explain IN DETAIL how ciphers are working for at least ONE word of your choice. You don't need to explain Binary/ASCII in detail.
