Security and reliability issues have always been a big challenge in digital communications. With the emerging 5G technologies, new requirements are introduced where latency reduction is one of the most important. In this paper, a joint security and reliability method is proposed to fulfil both requirements in a single step with reduced computational complexity that leads to reduced latency for 5G communication systems. Based on Advanced Encryption Standard (AES) cryptosystem and Low-Density Parity-Check (LDPC) codes, the proposed method processes encryption and encoding at the same time. MATLAB simulation results show that the proposed method performs better compared to the previous conventional methods where encoding is done after encryption.
