Three-party quantum secure direct communication based on Greenberger-Horne-Zeilinger states

Quantum Physics 2009-11-13 v1

Abstract

We present a three-party simultaneous quantum secure direct communication (QSDC) scheme by using Greenberger-Horne-Zeilinger (GHZ) states. This scheme can be directly generalized to NN-party QSDC by using nn-particle GHZ states. We show that the many-party simultaneous QSDC scheme is secure not only against the intercept-and-resend attack but also against the disturbance attack.
