Because of the security of the symmetric cryptosystem, a secure communication scheme based on PEG-LDPC codes has been put forward in this paper. The secure and reliable integrated communication is based on hiding and changing generator matrix randomly and simultaneously under the premise of ensuring error correction ability of LDPC codes. The performance of LDPC codes constructed by PEG algorithm is excellent, and this algorithm can construct an LDPC code with arbitrary code length and code rate.
