Message encoding is the process to convert the text into random and meaningless unrecognizable text called ciphertext. Decoding is the process to convert that ciphertext to the original text. This ...

This method takes the ciphertext and a substitution key, and uses the key to replace each character in the ciphertext with its corresponding character in the key. It also handles spaces and ...

[Sam Greydanus] created a neural network that can encode and decode messages just as Enigma did. For those who don’t know, the Enigma machine was most famously used by the Germans during World War II ...

Encryption—the process of sending a scrambled message that only the intended recipient’s device can decode—allows private and public sectors alike to safeguard information. Traditional encryption uses ...

Abstract: Li, Ling, Xing, and Yeo (LLXY) have proposed a code-based encryption scheme based on factoring in finite fields. The security of the scheme relies on both the decoding problem for (q – ...
