Is quantum key distribution suitable for steganography?

Is quantum key distribution suitable for steganography? Recently a quantum steganographic communication protocol based on quantum key distribution (QKD) was proposed, where it is believed that QKD is a kind of suitable cover of a steganographic communication because QKD itself is not deterministic communication. Here we find that, as a special cryptographic application, the procedure of QKD can be used for deterministic secure communication, and consequently it is not suitable for steganography. Due to similar reasons, other quantum cryptographic schemes, including quantum secret sharing and quantum secure direct communication, are not suitable for steganography either. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals

Abstract

Recently a quantum steganographic communication protocol based on quantum key distribution (QKD) was proposed, where it is believed that QKD is a kind of suitable cover of a steganographic communication because QKD itself is not deterministic communication. Here we find that, as a special cryptographic application, the procedure of QKD can be used for deterministic secure communication, and consequently it is not suitable for steganography. Due to similar reasons, other quantum cryptographic schemes, including quantum secret sharing and quantum secure direct communication, are not suitable for steganography either.
