Embodiment Construction

[0014] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Further, in the present specification and the figures, a constituent element that actually has the same functionality is omitted, and the repeated description is omitted by additional reference numerals.

[0015]

[0016] >

[0017] First, a summary of an embodiment of the present invention will be described. As described above, in recent years, techniques are developed according to the results of the result of receiving the received signal between the devices. For example, in Patent Document 1, a technique of performing a portable machine is performed by transmitting a reception signal between the vehicleverher and the port.

[0018] By using such an authentication technique, for example, when the user having a portable carrier is within the distance specified by the vehicle, the door lock of the vehicle is released or the engine can be activated.

Abstract

The present invention ensures convenience and achieves safer inter-device authentication. A communication device is provided with a control unit that controls a process relating to the transmission or reception of a first authentication signal and a second authentication signal used in a first authentication process, which is authentication between the communication device and another communication device. The control unit further controls a second authentication process that is an authentication different from the first authentication process, and starts a process relating to the transmission or reception of a signal used in the second authentication process that is an authentication different from the first authentication process before the transmission or reception of the first authentication signal.

Description

Technical field [0001] The present invention relates to a communication device and a system. Background technique [0002] In recent years, techniques are developed based on the results of transmitting received signals between devices. For example, in the following Patent Document 1, a system that transmits a reception signal between the vehicleverher and the port is disclosed. [0003] Patent Document 1: Japan Kaiping 11-208419 [0004] In the above system, in order to improve the security, it is assumed that the structure of the authentication is complicated. However, in this case, there is a possibility that the user's convenience is lowered. Inventive content [0005] Accordingly, the present invention is accomplished in view of the above problems, and the object of the present invention is to ensure convenience and to achieve a more secure device authentication. [0006] In order to solve the above problems, according to a certain point of view of the present invention, a c...
