Confidentiality is the inability to deny. In cryptography, it is a security service by which evidence is maintained so that the sender and the recipient of data cannot deny having participated in the communication. There are two kinds of non$-$repudiation: "non$-$repudiation of origin" means the sender cannot deny having sent a particular message, and "non$-$repudiation of delivery" is when the receiver cannot say that they have received a different message than the one that they actually did receive.
