Quantum key distribution based on conference key agreement
Dong Pyo Chi, Sora Choi, Soojoon Lee
Pages. 189-195     



Applying multipartite entanglement purification protocol,
we present a quantum key distribution protocol between two parties
based on conference key agreement
(or quantum secret sharing of classical secrets)
as a generalization of quantum key distribution between two persons.
We analyze the security of the protocol
against an external eavesdropper and some dishonest members in two parties.

2. Properties of entanglement states
3. Protocols
4. Analysis of Security
