Low-density parity-check (LDPC) code is quite popular, in 1962, proposed by Rober.G.Gallager, its good quality of performance which shall be close to Shannon Limit. However, subject to the difficulty of hardware design before, it was not valued. Nowadays, LDPC codes have been applied to wireless communications, fiber-optic communications, digital video broadcasting-satellites (DVB-S), digital audio broadcasting (DAB), etc. The theoretical research field of LDPC codes mainly focus on performance analysis of decoding algorithms, methods of encoding, and optimizations of code structure. Here, we studied on wireless network information transmission encryption applied LDPC, using Advanced encryption Standard (AES) and hash function to achieve the protection of information security.
