Abstract
To strengthen security for the case where beam forming is used. A first device according to the present invention is provided with an information acquisition unit for acquiring information pertainingto beam selection, and a key generation unit for generating a security key for wireless communication between a base station and a terminal device on the basis of the information pertaining to the beam selection.
Description
technical field [0001] The present invention relates to devices, methods, systems, programs and recording media related to beams and security enhancement. Background technique [0002] In recent years, communication traffic in mobile communication systems has increased. So to speak, this phenomenon is due to the fact that many communication devices use Long Term Evolution (LTE) as an access technology and various applications operate on the smartphone. For example, operators of mobile communication systems and national agencies related to mobile communication systems are discussing countermeasures such as additional allocation of used frequencies. In particular, additional allocations of high frequency bands (eg, 6 GHz to 100 GHz) where wider bandwidths are expected to be available are discussed. In addition, research and development on access technologies of mobile communication systems have been continuously conducted to cope with the increase in communication traffic. ...
