WebApr 12, 2016 · How can we modify classical cryptography system to provide non-repudiation? I want to ensure non-repudiation in symmetric key cryptography so that we can find out who is sender of a particular message.As sender and receiver share the same key, we can't find out who the sender was. Have both sides use hash based signatures to sign … WebMACs do not provide non-repudiation because in symmetric cryptography the receiver also has the same secret key, so there's no way for the receiver to prove that the sender and not the receiver signed the message. As emphasized previously, using a shared key for authentication requires the shared key to be properly secured. google forced ipo
