Abstract: Wireless communication channels are highly vulnerable to security attacks and channel noise. Most wireless communication systems deploy advanced encryption standard (AES) and turbo code for security and reliability. However, the sequential process of encryption and encoding increases the resources, computational cost and reduces the overall error correction performance. A hybrid turbo code (HTC) for encryption and error correction is proposed. The HTC deploys a proposed Weierstrass elliptic curve interleaver (WECI) for random shuffling of the input bits. The difficulty of solving the elliptic curve discrete logarithm makes the WECI cryptographically strong. The simulation results of HTC depict a bit error rate of almost 10-3.8 at a signal-to-noise ratio of 2 dB similar to the conventional turbo code. Moreover, it provides security and reliability to the transmitted data at a reduced computational cost and memory as compared to the conventional system using AES followed by turbo code.
