This addresses secure quantum communication for cryptography applications, but appears incremental as it builds on Shamir's no-key protocol.
The authors tackled the problem of secure quantum communication by developing a quantum no-key encryption scheme with mutual authentication that is unconditionally secure and allows permanent reuse of authentication keys.
We realize shamir's no-key protocol via quantum computation of Boolean permutation and private quantum channel. The quantum no-key (QNK) protocol presented here is one with mutual authentications, and proved to be unconditionally secure. An important property of this protocol is that0 its authentication key can be reused permanently.
