Improving the Security of Quantum Protocols via Commit-and-Open
Ivan Damgaard, Serge Fehr, Carolin Lunemann +2
We consider two-party quantum protocols starting with a transmission of some random BB84 qubits followed by classical messages. We show a general "compiler" improving the security…

Composing Quantum Protocols in a Classical Environment
Serge Fehr, Christian Schaffner
We propose a general security definition for cryptographic quantum protocols that implement classical non-reactive two-party tasks. The definition is expressed in terms of simple q…

Secure Identification and QKD in the Bounded-Quantum-Storage Model
Ivan Damgaard, Serge Fehr, Louis Salvail +1
We consider the problem of secure identification: user U proves to server S that he knows an agreed (possibly low-entropy) password w, while giving away as little information on w…
