Insecurity of a relativistic quantum commitment scheme

Quantum Physics 2023-07-25 v2

Abstract

We propose a cheating strategy to a relativistic quantum commitment scheme [Sci Rep 2014;4:6774] which was claimed to be unconditionally secure. It is shown that the sender Alice can cheat successfully with probability 100%, thus disproving the security claim.
