Definition: Undecoyed is a term in the field of cryptography and digital security. It refers to a type of message that cannot be decoded by an attacker, even if the sender or receiver can decrypt it using known techniques.

Undecoyed messages are often used in applications such as digital signatures, encryption, and authentication, where they serve
