Digital communications have always faced significant dependability and security challenges. Latency reduction is one of the most crucial new needs brought forth by the developing 5G technologies. A combined security and reliability solution is put forth in this research to meet both objectives in a single step with lessened computing complexity, which lowers latency for 5G communication systems. The suggested technique simultaneously performs encryption and encoding using the Low-Density Parity Check (LDPC) codes and the Advanced Encryption Standard (AES) cryptosystem. The suggested technique outperforms earlier traditional methods that execute encoding after encryption, according to MATLAB simulation findings. From 2G to 4G, digital communications have seen many developments in recent years. The rapidly expanding needs for communication technology created new expectations that the next 5G network must meet. Reduced latency is one of several modifications that these new applications, however, need. The propagation and switching delays, as well as the computational complexity of the systems, are what generate latency.
