چکیده
|
This paper proposes an efficient joint secret key encryption-channel coding cryptosystem, based on regular extended difference family quasi-cyclic low- density parity-check codes.the key length of the proposed cryptosystem decreases up to 85 percent using a new efficient compression algorithm. cryptanalytic methods show that the improved cryptosystem has a significant security advantage over rao-nam cryptosystem against chosen plaintext attacks, benefiting from an improvement on the structure of the rao-nam cryptosystem and proper choices of code parameters. moreover, the proposed cryptosystem benefits from the highest code rate and a proper error performance
