| description | A security system includes a portable terminal, a communication device communicating with the portable terminal, and a determination unit determining validity of the portable terminal. Phase data acquired from distance measuring radio wave is used to determine validity of communication between the portable terminal and the communication device. The received phase data of the distance measuring radio wave varies according to the distance from a transmission source. When the communication device and the portable terminal are fixed, and the communication device and the portable terminal have transmitted and received distance measuring radio waves having the same specific frequency, vehicle acquisition phase data and terminal acquisition phase data are the same. The determination unit determines, by using this two types of phase data, the validity of communication between the communication device and the portable terminal is determined. |
