At this time, using the token in the application installation information (the token held by the application), authentication for establishing a line is performed between the smart phone 10 as the first device and the HDMI dongle 20 as the second device. It will be.
認証では、スマートフォン10から送られるトークンがHDMIドングル20に備えられたトークンと一致しない場合には回線確立を行わず、スマートフォン10から送られるトークンがHDMIドングル20に備えられたトークンと一致した場合のみに回線確立を行う。また、この逆に、HDMIドングル20から送られるトークンがスマートフォン10に備えられたトークンと一致しない場合には回線確立を行わず、HDMIドングル20から送られるトークンがスマートフォン10に備えられたトークンと一致した場合のみに回線確立を行う。このようにして、相互認証された安全な通信が自動的に確保される。なお、相互認証は、2つのデバイスが同じトークンを保持することが確認されるものであればよい。上記のようにトークンを保持することの確認に加えて、デバイスの情報や他の付加情報を互いに送受して確認をおこなっても良いし、暗号化したものを送受して認証を行なってもよく、特に定められた手法が用いられる必要はない。
In the authentication, if the token sent from the smartphone 10 does not match the token provided in the HDMI dongle 20, the circuit establishment is not performed, and only if the token sent from the smartphone 10 matches the token provided in the HDMI dongle 20 To establish a circuit. Conversely, if the token sent from the HDMI dongle 20 does not match the token provided on the smartphone 10, the circuit establishment is not performed, and the token sent from the HDMI dongle 20 matches the token provided on the smartphone 10 Only when the connection is established. In this way, mutually authenticated secure communications are automatically secured. Note that mutual authentication may be performed as long as it can be confirmed that two devices hold the same token. As described above, in addition to the confirmation of holding the token, the information of the device and other additional information may be transmitted and received mutually for confirmation, or the encrypted one may be transmitted and received for authentication. There is no need to use a specifically defined method.
上記では、カメラ部18により二次元バーコードBCの撮像を行い、インストールの指示を操作部14から入力すると、直ちにアプリケーションのダウンロード及びインストールへと進んだが、アプリインストール情報中の識別情報に対応するアプリケーションが既にインストールされているか否かを検出し、インストール済みの場合には、アプリインストール情報中のトークンをアプリケーションへ渡して、トークンの書き換えを行うようにしても良い。これにより、同じアプリケーションにより制御が可能なHDMIドングル(及びテレビ)が複数存在する場合に、切替え毎にインストールを行う必要がなく便利である。
In the above, imaging of the two-dimensional bar code BC is performed by the camera unit 18, and when an installation instruction is input from the operation unit 14, the process immediately proceeds to downloading and installing the application, but the application corresponding to the identification information in the application installation information If it is already installed, the token in the application installation information may be passed to the application to rewrite the token. As a result, when there are a plurality of HDMI dongles (and televisions) that can be controlled by the same application, there is no need to install for each switching, which is convenient.
なお、第1のデバイスと第2のデバイスは、スマートフォンとHDMIドングルに限定されない。例えば、パーソナルコンピュータ、プリンタ、デジタルカメラ、携帯電話機、その他の電気製品において、同様の機能を備えるものであれば特に限定されない。ただし、第2のデバイスにおいては、アプリインストール情報を出力する機能を有することが必要である。アプリインストール情報を出力する機能は、表示機能の他、プリントアウト機能、音声出力機能等、何等かの媒体によりアプリインストール情報をユーザに報知できれば良い。また、アプリインストール情報を第2のデバイスから近接無線通信回線を介して第1のデバイス提供(送信)するようにしてもよい。近接無線通信の機能は、第1のデバイス及び第2のデバイスが備える。ここに、近距離無線通信とは、近接場型の無線通信(near field communication)を意味し、約1メートル~数センチ程度の極短距離の通信であり、「非接触通信」と同等の通信を指すものである。その他、本発明はその趣旨の範囲において適宜変更して実施することができるものであることは言うまでもない。
The first device and the second device are not limited to the smartphone and the HDMI dongle. For example, personal computers, printers, digital cameras, cellular phones, and other electronic products are not particularly limited as long as they have similar functions. However, the second device is required to have a function of outputting application installation information. The function of outputting the application installation information may be such that the user can be notified of the application installation information by any medium such as a printout function and an audio output function in addition to the display function. Also, the application installation information may be provided (sent) from the second device via the close proximity wireless communication line. The function of the close proximity wireless transfer is provided to the first device and the second device. Here, near-field wireless communication means near field wireless communication (near field communication), communication of an extremely short distance of about 1 meter to several centimeters, and communication equivalent to "contactless communication". Point to Besides, it goes without saying that the present invention can be implemented with appropriate modifications within the scope of the present invention.
