Monoalphabetic Cipher

Why
Monoalphabetic ciphers allow us to create a simple cipher that is easily encoded and decoded.

What
Monoalphabetic ciphers are defined as ciphers that take an input message and uniquely assigns it to a message in the ciphertext space

Vulnerabilities
Because of this one-to-one mapping, this sort of cipher is especially vulnerable to frequency analysis attacks

Strengths
It can be agreed that combining multiple simple ciphers result in a strong cipher.
