Quantum Identity Authentication

Functionality

Authentication is a building block which proves something is true or genuine between two parties, the suppliant (prover) and the authenticator (verifier). There are two types of authentication, data authentication and identity authentication. In data authentication, the authenticator checks the claim in a non-interactive process called offline mode, i.e. there is no interaction after the message has been sent. In identity authentication, the parties perform an interactive protocol where suppliant proves the possession of some unique data.

Properties

• The security of the protocol requires that no sensitive information is exchanged during its execution can leak to the eavesdropper.
