Errors in a transmitted message is unavoidable since noise is inevitable in any communication channel. For reliable transmission of messages, the bit error rate has to be kept at an acceptable rate by the use of proper error control coding schemes. To ensure that the transmission is also secure, data encryption is used as an integral part of the system. This paper deals with the design and analysis of a secure and reliable communication system accomplished using logistic map-based chaotic encryption and turbo product codes. The system is simulated using MATLAB and it is shown that the use of encryption for secure communication does not degrade the system performance. The hardware design of the decoder is also done and verified in Verilog using the same set of vectors as obtained from the system simulation. BER performance was analyzed in all the different scenarios and the correctness of the design was established. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
