This paper proposes a novel scheme named CodeHop, which provides both information reliability and security using code hop ping based on low-density parity-check (LDPC) codes. In contrast to traditional systems that perform error correction and encryption at different layers, CodeHop combines these two operations into a single step at physical layer, such that each plaintext message is jointly encoded and encrypted by a hopping parity-check matrix. According to a pseudo-random number generator… CONTINUE READING
