Ehy guys, I read that signature guarantee non repudiation.
But in generale exist a way ti no guarantee non repudiation with signature?
Enc(signature(m) should be guarantee
Instead for me Signature (Enc(m)) not.
Because in First case we send a signature but se encrypt before with a servire share Key (so Is very secure because u need the key before produce signature. In the second case the signature Is public and anyone can try to forge It and impersonify the signer. Right?
