For the secret key agreement from common information, a general formula of the secret key capacity is given, but a specific formula of secret key capacity has not present for secret key agreement from Gaussian correlated information, which is typical case in wireless channels.  This paper deals with the theoretical analysis on secret key capacity for the mobile communication channel model.  The analysis result shows that the upper band of secret key capacity is given with conditional mutual information and that the formulas of upper and lower bands are expressed as functions of the signal-to-noise power ratio and the noise power ratio of eavesdropper to legitimate user.  The analysis result also shows that secret key capacity can approximately be given by conditional mutual information in the case that noise power ratio of eavesdropper to legitimate user is large.","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.2017.0000014470","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
