Dans cette lettre, un schéma de brouillage de code basé sur les erreurs de messages artificiels est proposé pour sécuriser les communications dans les canaux d'écoute électronique avec réciprocité de canal. Dans le schéma proposé, les erreurs de bits de message artificielles convenues entre l'émetteur et le récepteur légitimes sont ajoutées aux bits de message brouillés au niveau de l'émetteur avant la procédure de codage de canal, à travers laquelle les erreurs artificielles sont générées en utilisant le canal réciproque entre l'émetteur légitime. et le récepteur. En raison de l’inaccessibilité aux informations sur l’état du canal entre l’émetteur et le récepteur légitimes, une écoute indiscrète ne parviendrait pas à compenser parfaitement les erreurs artificielles. Ainsi, en plus des erreurs de décodage, les erreurs artificielles résiduelles seront également réparties sur le message déchiffré de l'écoute indiscrète par l'effet de propagation des erreurs du brouillage de code. Par conséquent, contrairement au schéma de brouillage de code classique, le schéma proposé peut fournir une forte confidentialité des messages pour des canaux d'écoute non dégradés, par exemple lorsque l'écouteur ne rencontre aucune erreur de décodage. De plus, étant donné que les erreurs artificielles sont introduites avant la procédure de codage de canal, les erreurs résiduelles propagées dans le message déchiffré restent non détectées après les procédures de décodage de l'écoute indiscrète. Les résultats de simulation confirment que le schéma proposé surpasse le schéma conventionnel et offre une forte confidentialité des messages dans les canaux d'écoute électronique.

Abstract: In this letter, an artificial message error-based code scrambling scheme is proposed for secure communications in wiretap channels with channel reciprocity. In the proposed scheme, the artificial message bit errors agreed between the legitimate transmitter and receiver are added to the scrambled message bits at the transmitter prior to the channel encoding procedure, through which the artificial errors are generated by using the reciprocal channel between the legitimate transmitter and receiver. Because of the inaccessibility to the channel state information between the legitimate transmitter and receiver, an eavesdropper would fail to compensate for the artificial errors perfectly. Thus, in addition to decoding errors, the residual artificial errors will also be spread over the descrambled message of the eavesdropper by the error spreading effect of code scrambling. Therefore, unlike the conventional code scrambling scheme, the proposed scheme can provide strong message confidentiality for non-degraded eavesdropping channels, e.g., when the eavesdropper experiences no decoding errors. Furthermore, given that the artificial errors are introduced before the channel encoding procedure, the spread residual errors in the descrambled message remain undetected after the decoding procedures of the eavesdropper. Simulation results confirm that the proposed scheme outperforms the conventional scheme and provides strong message confidentiality in wiretap channels.
