Abstract

The symmetric cryptography provides some authentication, but the receptor has no way of convincing a third part that the message is authentic. We will propose a cryptographic protocol using public key instead of symmetric key to join the reliability given for the digital signature with the security given for the anonymity.

Keywords: security, cryptographic protocols, anonymity
