 message encryption stage, to be certain that,
 even in the worst case scenario, the attacker
 will not be able to obtain the message content.
+Doing so makes our steganographic protocol, in a certain extend, an asymmetric one.

-In this research work, we thus propose to combine tried and

 The remainder of this document is organized as follows. 
-Section~\ref{sec:ourapproach} presents the details of our steganographic scheme.
-Section~\ref{sec:experiments} shows experiments on image quality, steganalytic evaluation, complexity of our approach 
-and compares it to state of the art steganographic schemes.
