Non-reconciliation Secret Keys Based Secure Transmission Scheme Using Polar Codes
Zheng Wan, Kaizhi Huang · 2019
Focusing on the problem of information leakage and communication cost in information reconciliation, this paper introduces a non-reconciliation secret Keys based transmission scheme (NASKT) for machine to machine(M2M) communications in Internet of Things (IoT) networks, which uses polar codes to guarantee no error transmission. First, the improved Kalman filter preprocessing algorithm is used to reduce the quantized bit error rate (QBER). Then, QBER is modeled as the transmission bit error rate of the additional white Gaussian noise (AWGN) channel. Finally, the polar codes are designed based on the equivalent AWGN channel and system performance requirements to guarantee the security of transmitted information. Numerical simulations verify that the secure M2M transmission scheme based on the Non-reconciliation secret Keys using polar codes can realize the One-Time Pad lightweight security.
