Loop cards are a great game that can be played individually or as a class. They are perfect for review key vocabulary or questions at the end of a topic or when revising for an exam.
Instructions
Cut out the cards from the paper horizontally (but don't cut them in half!) and then shuffle them.
Now start joining each question on the right hand side of the card to the matching answer on the next card.
Carry on until all the cards loop together and you have competed the game!
Hint: Make sure that you set your paper to portrait to print 4 cards per sheet of A4 paper.
A transposition cipher that is created by writing the plaintext horizontally in a zigzag pattern, and then reading off the ciphertext vertically.
Cryptanalysis
The study and practice of breaking codes and ciphers, usually with the goal of deciphering encrypted messages without knowledge of the secret key.
Vigenere Cipher
A method of encrypting alphabetic text using a series of different Caesar ciphers based on the letters of a keyword.
Alphabet
A set of letters or symbols used to represent a language or system of writing, ordered in a fixed sequence.
Decryption
The process of converting encoded text to its original form by employing a deciphering algorithm and the identical confidential key utilized during encryption.
Kasiski Examination
A cryptanalytic technique used to try and discover the length of the keyword used in a Vigenere Cipher by detecting repeating patterns in the ciphertext.
Encryption
The procedure of converting plain text into ciphered text by employing an algorithm for secure encoding and a confidential key.
Substitution Cipher
A cipher that replaces each plaintext letter or symbol with a different letter or symbol to create the ciphertext.
Plaintext
The original message or data that is to be encrypted or decrypted in its unencrypted form.
Caesar Cipher
A monoalphabetic substitution cipher in which each letter in the plaintext is shifted a certain number of places down the alphabet.
