As one field, there is group secret key agreement to notify of the difference between the series of RSS in star and chain connection system.  However, the conventional method has a problem in derivation of theoretical expression of the secret key capacity.  This paper deals with a close numerical formula of upper and lower limit of the secret key capacity to be given in mutual information for chain connection systems.  This paper derives new theoretical expression of the secret key capacity that is a function of the SN ratio by new theoretical analysis for the mutual information.  As a result, numerical computation shows that the upper limit of the secret key capacity accords with the lower limit in high SN ratio.  In addition, the simulation results show validity of theoretical expression because the simulation results accord with theoretical characteristics well.","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":"10.14988/00027803","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
