Add to ORKGMonoalphabetic cipher is an encryption substitution method that maps each alphabet to another alphabet randomly. This method is different from the Caesar cipher, which only shifts the alphabet. In addition, in monoalphabetic ciphers, substitution tables are used to store keys, where these keys are useful for mapping alphabets from plaintext to ciphertext. However, in reality the use of substitution tables still has difficulties. Based on this, an idea emerged to analyze whether the substitution table could be replaced by a mathematical equation to be used as a key to the monoalphabetic cipher. And in this case, the mathematical equation used is a quadratic equation.
