In this thesis, we study communication channels in a non cooperative context and more particularly, error correcting codes reconstruction on one hand, and steganalysis on the other hand. We play an unauthorized observer who wants to have access to the information exchanged between two legal users. Our researches on algorithms to reconstruct error correcting codes lead us to propose a generic approach for linear block codes, convolutional and turbo codes. We analyze the Sicot-Houcke algorithm and use it as a base to design an entirely automatic technique to reconstruct convolutional codes. Moreover, this technique has a better complexity than existing ones. Finally, we adapt theses results to retrieve the parameters of turbo code encoders. I...
