Steganalysis of Continuous Variable Quantum Steganographic Protocols

Steganography is the study of concealing and sending a secret message by making eavesdropper unaware its presence. First ever attempt to propose steganography via quantum key distribution (QKD) was made Martin in his paper where BB84 QKD used for communicating steganographic messages. The protocol have recently been found be insecure against detection based steganalysis attack which uses ambiguous state discrimination. In this work, we extend previous methods develop new continuous variable protocols using analyze their performance steganalysis.
