secret key agreement scheme using radio propagation characteristics has been studied as a countermeasure against eavesdropping in wireless communication．Most of secret key agreement schemes using radio propagation characteristics uses quantization of sample value of the received signal strength variation．This paper proposes a method of sharing secret key using level crossing time information based on a phase difference variation that is not considered．In the proposed system，each station alternately transmits and receives signal and measures the propagation characteristics．In order to reduce the influence of noise，the noise is removed from received signal by using filter in frequency domain．From the measured radio propagation characteristics at the transmitter station，set a certain sample value to the standard value．The standard value to detect a level crossing is transmitted from a transmitter station to a receiving station through a public channel．The receiving station acquires time information when a level cross for the standard value．The information of the level crossing time is acquired continually by repetition of this processing．After the receiving station calculates existing space data between the acquired time，the space data is encoded to binary．The binary encoding bit is a bit sequence for secret key generation．","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.2018.0000000165","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
