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 cryptanalytic technique used to try and discover the length of the keyword used in a Vigenere Cipher by detecting repeating patterns in the ciphertext.
Pigpen Cypher
Also known as the Masonic Cipher, it is a substitution cipher used in cryptography that replaces letters with symbols and shapes.
Frequency Analysis
The study of the frequency and distribution of letters or symbols in a text to help break a cipher.
Autokey Cipher
"A polyalphabetic cipher similar to the Vigenere Cipher, but using the plaintext itself as part of the key sequence in order to overcome a weakness observed in the original Vigenere Cipher."
Secure Communication
Communication that is encrypted and protected from unauthorized access
Rainbow Table
A precomputed table used in password cracking to reverse cryptographic hash functions and quickly determine the original password.
Ciphertext
