There are few studies of group secret key agreement in this field, but there is a method to notify of the difference between the series of RSS.  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.  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.  Numerical computation also shows that leakage information increases with increase of the number of the terminals.  Furthermore, the result of the computer simulation shows validity of theoretical expression.","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":"10.14988/00027350","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
