Monoalphabetic ciphers are simple substitution ciphers where only one alphabet is used to substitute the characters from the plaintext and replace them one-for-one, where each character in the plaintext is always substituted with the same character in the ciphertext. This means that these ciphertexts are susceptible to frequency analysis.
Frequency analysis is a technique where a sample text is analysed to find out how often each character appears, which is used to build a histogram. This becomes the reference guide.
In this lab you will explore this by decrypting a classical cipher, the Caesar cipher.
This lab is part of a series on cyber network security.
Upon completion of this lab you will be able to:
Show how monoalphabetic ciphers are susceptible to frequency analysis
