Abstract(in English) | As a countermeasure scheme against eavesdroppers in wireless communications, key agreement schemes, using an ESPAR (Electronically Steerable Parasitic Array Radiator) antenna and the reversibility of the radio propagation, have been proposed. However, the schemes require an error correction process to avoid a key disagreement between legitimate users. This paper proposes an error correction scheme using product codes, which can be decoded by a turbo decoder. Simulation results conducted assuming an indoor environment show that the proposed error correction scheme achieves block error rate of 10^<-2> at SNR of 12dB. Moreover, conditional mutual information is calculated for the quantitative evaluation of safety, so that the proposed scheme is more effective at low SNR, compared with the conventional scheme using a table-aided decoding. |
