Abstract(in English) As a counter measure scheme against eavesdroppers on wireless communication, the secret key agreement system has been proposed using an ESPAR (Electronically Steerable Parasitic Array Radiator) antenna, and using the propagation reciprocity between two users. However, this system requires an error correction process to avoid a key disagreement between regular users. This paper proposes an algorithm based on table-aided soft-decision decoding for the error correction process. Simulation results conducted for indoor IEEE 802.15.4/ZigBee^ environment show that nearly 100% successful key generation can be achieved by using the proposed error correction scheme. Moreover, compared with former error correction scheme, the proposed method makes it possible to reduce the key correlation between regular users and eavesdroppers.
