Caesar Cipher• It is a Substitution Cipher that involves replacing

each letter of the secret message with a different letter of the alphabet which is a fixed number of positions further in the alphabet.

ExampleIn this example, each letter in the plaintext message has been shifted 3 letters down in the alphabet.

Plaintext: This is a secret messageCiphertext: wklv lv d vhfuhw phvvdjh

Caesar CipherDecipher:Mx mw rsx tpeywmfpiNo. of shifts: 4

Ans:It is not plausible

Atbash Cipher• The Atbash cipher is a very specific case of a

substitution cipher where the letters of the alphabet are reversed. In otherwords, all As are replaced with Zs, all Bs are replaced with Ys, and so on.

• Because reversing the alphabet twice will get you actual alphabet, you can encipher and decipher a message using the exact same algorithm.

Atbash Cipher• Decipher this: Ziv Blf Irtsg

Ans: Are You Right

Pigpen Cipher

The pigpen cipher is a simple substitution cipher exchanging letters for symbols based on a grid.

team who gave the challenge gets -100.3) If that team cannot answer it correctly it gets -50 and the

team who gave challenge gets +50.4) Time : 1 min5) No passing.

Tap CodeEach letter was communicated by tapping two numbers. The first designated the horizontal row and the second designated the vertical row. The letter "X" was used to break up sentences and the letter "C" replaced the letter "K". For "WATER" the code would be the following..... .. . . .... .... . ..... .... ..

Rail Fence Cipher

• In the rail fence cipher, the plaintext is written downwards on successive "rails" of an imaginary fence, starting a new column when the bottom is reached. The message is then read off in rows. For example, if we have 3 rails and a message of "This is a secret message", you would write out:

T S A C T S G

H I S R M S E

I S E E E A J

• The last J is just a random letter to fill in the space. The secret message is then condensed and regrouped.

Morse Code• Morse code is a method for transmitting information, using

standardized sequences of short and long marks or pulses - commonly known as "dots" and "dashes" - for the letters, numerals, punctuation and special characters of a message.

Example:‘Winners’ is encoded as follows:.-- .. -. -. . .-. ...

Decode:... - .- -.-- .... ..- -. --. .-. -.-- .-- .... -.-- ..-. --- --- .-.. .. ... ....

Face-Off

Rules1) Each team will have 5 mins to encrypt MESSAGE of their choice using

CAESAR CIPHER2) The message encrypted should be legible and meaningful. Which means

it can’t be random words. The message must be a sentence or phrase.3) The team to correctly decipher the code first wins.4) If wrongly decoded the team loses.5) The No. of shifts should be from 1-5.6) The encoding team will not inform the opposite team about the number

of shifts.7) But the judges will be told before the encryption begins

Caesar Cipher• It is a Substitution Cipher that involves replacing

each letter of the secret message with a different letter of the alphabet which is a fixed number of positions further in the alphabet.

ExampleIn this example, each letter in the plaintext message has been shifted 3 letters down in the alphabet.
