I got confused with private / public key cryptosystem and Digital Certificates. If public key cryptosystem can provide non-repudiation, why do we need a Digital Certificate?

    A Digital Certificate provide the correspondence key-person identity.
    The CA who have signed the certificate guarantee that the public key is really Alice's Key.
