| Abstract(in English) | Physical layer security, which exploits wireless channel fading to realize secure transmission, has been an emerging research topic recently. Based on the concept of physical layer security, we propose a secure cooperation scheme by using fountain codes to resist untrustworthy relay in cooperative relay networks. In fountain-coded transmission systems, enough fountain packets are necessary for the receivers to decode the source information. We introduce a transmit power control strategy in this report to make that the destination has a higher packet reception rate than the relay, and thus security is achieved. Both decode-and-forward and amplify-and-forward relaying protocols are considered and their intercept probabilities are analyzed respectively. It is further observed that the security is also enhanced as the number of source packets increases. |
