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. Simulation results conducted for an indoor IEEE802.15.4/ZigBeeTM environment show that nearly 100 % successful key generation can be achieved by using the proposed key disagreement correction scheme. Moreover, compared with the conventional key disagreement correction scheme, the proposed scheme makes it possible to reduce the key correlation between regular users and eavesdroppers.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000011244","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学理工学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Science
