A Secure Channel Coding Scheme for Efficient Transmission of Remote Sensing Data over the LEO Satellite Channels

Both secure and error control coding are very extensive subjects, each with a variety of sub-disciplines. In this paper, we develop a secure channel coding (joint encryption-channel coding) scheme based on concatenated turbo codes for more efficient and secure transmission of the LEO satellite data. Reliability and security are achieved by adapting the pseudorandom puncturing strategy with the change of distance between satellite and ground station in the communication seance, to issue further burdened by reducing energy consumption or increasing bit rate of data transmission. Simulation results show the relevance and superior performance of the proposed scheme compared with the traditional data transmission system.
