 Deniable authentication

Deniable authentication is a cryptographic concept that allows a party to prove the authenticity of a message or a statement without the ability to later deny having sent it, while also ensuring that the evidence of this authentication cannot be used to compel the party to admit to sending the message under certain conditions. In simpler terms, it provides a way for the sender of a communication to authenticate their message while also being able to disclaim responsibility or knowledge of the message if needed.
