- the base station function unit 61 responds to the tunnel establishment request from 81 (step S42), a tunnel connection is established between the communication terminal 81 and the base station function unit 61 (step S43). According to this configuration, since the authentication function unit in the local server 5 can be integrated, the load on the local server 5 can be reduced.
- Pre-authentication performed by the local server 5 in response to an authentication request from the vehicle 8 includes authentication of the location information of the vehicle 8, authentication of the communication terminal 81 connected to the local network base station 6, or vehicle information (vehicle identification number, number plate, driver's name, etc.). According to this configuration, by adding not only the position information of the vehicle 8 but also the information related to the vehicle 8, it is possible to easily confirm the other party of the authentication.

As a result, if there is no problem, a vehicle authentication response is made (step S63). According to this configuration, since the generation of authentication requests is limited, it is possible to reduce the amount of communication related to authentication and the load on the local server 5 that performs authentication.
- Embodiment 2 (Local server connection source authentication) As means for confirming that the vehicle 8 is legitimate, means different from those in the first embodiment will be described.

- the local server 5 when the local server 5 receives vehicle information (image data) from the gate device 10 (step S91), it transmits a vehicle authentication start request to the vehicle 8 (step S92). Then, in response to this, the vehicle 8 may transmit a pre-authentication request (step S93). According to this configuration, it is possible to prevent an erroneous operation of not requesting vehicle authentication from the vehicle 8 .
- the authentication process can proceed smoothly.
- FIG. 10 is an operation sequence diagram showing an example of using a one-time password for accessing limited information within a local network.
- a one-time password is included in the vehicle authentication response when performing authentication between the vehicle 8 and the local server 5, and communication is performed from the state of traveling in the public network area 7 to the state of traveling in the local network area 9.
- authentication is performed using a one-time password when authenticating a connection request to the local server 5 .
- the one-time password is a password that is valid only for the time that is expected to be required for moving from the position of the vehicle 8 to the entrance of the local network area 9 .
- the local server 5 sends the vehicle 8 a one-time password for accessing limited information in the local network. It is included in the vehicle authentication response and notified (step S101).
- the vehicle 8 notifies the local server 5 of the one-time password (step S102), and when the local server 5 completes authentication using the one-time password, a server connection response is made (step S103). Communication is established with the local server 5 . According to this configuration, the time required for authentication by the local server 5 can be shortened, so information can be acquired smoothly.
- the one-time password is only valid for a limited time, it is possible to prevent the illegally obtained one-time password from being abused or tampered with.
- FIG. 11 shows an operation sequence for providing the private map information 11 (small-area map information) held by the local server 5 to the vehicle 8 .
- the private map information 11 is acquired and combined with the public road map information 12, so that the current position of the vehicle 8 passes through the entrance of the private land, It represents an example of setting a travel route to a destination point.
- the vehicle 8 is located outside the local network area 9 and notifies the local server 5 of the location information (step S111).
- the local server 5 distributes the private map information 11 (small area map information) of the vicinity of the entrance to the vehicle 8 (step S112).
- the vehicle 8 synthesizes the distributed private map information 11 (small-area map information) and the public road map information 12 and uses it for selecting a travel route.
- the public road map information 12 does not include the details of the private map information 11. For this reason, even if the public road map information 12 and the private map information 11 are simply obtained, the entrance to the private land is not always open to the public road, which makes it easier to enter the private land. It happens that it is not done.
- the current position of the vehicle 8 is displayed on the map information (composite map information 13) obtained by combining the public road map information 12 and the private map information 11. After that, the optimum driving route can be selected, and the driving route from the entrance to the private property to the destination point can be set.
- a roadside unit may be installed near the entrance of the local network area 9 to detect the approach of the vehicle 8 to the entrance of the local network area 9 .

- map information it is also possible to distribute the map information to be distributed in advance from the local server 5 to the vehicle 8 according to the type of user. In other words, for vehicles that simply deliver parcels, only the entrance of the local network area and the counter (destination point) for receiving parcels are displayed, and other areas are not clearly indicated. Then, it is also possible to change the disclosure area based on the private map information in accordance with the pre-registered user. According to this configuration, it is possible to prevent the information of the local network area not used by the user from being unnecessarily distributed, thereby improving confidentiality.
- the configuration may be such that all private map information is distributed. According to this configuration, the delivery destination of the information in the local network area 9 is limited by being registered in advance, so that advance measures are taken to prevent leakage of confidential information, thereby improving confidentiality.
- the user may be configured such that only the necessary routes are delivered out of the private map information. According to this configuration, out of the local information, only the necessary routes are distributed, so that it is possible to prevent temporary users from accessing other confidential information, thereby improving confidentiality.
- the data received within the local network area 9 are all deleted when the vehicle 8 leaves the local network area 9 . That is, when leaving the private land, the content of the information device is confirmed, and the private map information acquired when entering the private land is erased. This is to acquire private map information with a flag and to erase the information with this flag. According to this configuration, private map information cannot be taken out from the vehicle 8 that has left the local network area 9, so confidentiality is improved.
- the vehicle 8 used in the information distribution system of the present application includes a communication terminal 81, the function of which is controlled by a control device provided inside.
- a control device provided inside.
- An example of the hardware of this controller is shown in FIG. It is composed of a processor 100 and a storage device 200.
- the storage device 200 includes a volatile storage device such as a random access memory and a non-volatile auxiliary storage device such as a flash memory. Also, an auxiliary storage device such as a hard disk may be provided instead of the flash memory.
- the processor 100 By executing the program input from the storage device 200, the processor 100 performs communication between the communication terminal 81 and the local server 5 and the local network base station 6, for example.
- the program is input from the auxiliary storage device to the processor 100 via the volatile storage device.

Abstract
Description
この車両の走行の案内において、道路地図情報として提供されるのは、公道(一部の私道も含まれている)の情報(以下、公道地図情報という)であって、私有地内の情報(以下、私的地図情報という)の提供は制限されている。
一方、私有地内に係る私的地図情報には、施設の配置情報および私有地内の交通ルールなど、機密情報が含まれることから機密保持を徹底させるという問題がある。
(ローカル網エリアの情報の事前取得)
実施の形態1の情報配信システムの構成を図1に示す。また、この情報配信システムの動作シーケンスを図2に示す。なお、この後の図中の同一符号は、各々同一または相当部分を示している。
図3は。ローカルサーバ5内に疑似端末機能部51を設けて、認証を事前に行う構成を示したものである。図3に示すように、車両8の通信端末81と、ローカルサーバ5の疑似端末機能部51と、ローカル網基地局6の中の基地局機能部61との間で通信のやり取りが行われる。
図4に示すように、車両8の認証が受け入れられた後に、車両8の通信端末81と疑似端末機能部51との間でローカルサーバの接続が行われ(ステップS41)、車両8の通信端末81からのトンネル確立要求に、基地局機能部61が応答する(ステップS42)ことによって、通信端末81と基地局機能部61との間のトンネル接続が確立される(ステップS43)。
この構成によれば、ローカルサーバ5内の認証機能部が一元化できるのでローカルサーバ5の負荷を軽減できる。
車両8からの認証要求に対してローカルサーバ5が行う事前認証は、車両8の位置情報の認証とともに、ローカル網基地局6に接続する通信端末81の認証、もしくは車両情報(車両識別番号、ナンバープレート、運転者氏名など)の認証の少なくとも1つの認証を行う。
この構成によれば、車両8の位置情報だけでなく、車両8に関係する情報を追加することによって、認証の相手先の確認を容易にすることができる。
図5に示すように、ローカルサーバ5は、端末認証部52、位置情報認証部53、および車両認証部54を備えている。端末認証部52は、接続許可端末情報521を有し、位置情報認証部53は、鍵情報531を有し、車両認証部54は、通行許可車両情報541を有している。また、車両8は、車両位置・移動方向検知部82、位置情報署名部83、GPS/GNSS84を備えている。車両位置・移動方向検知部82は、切替位置821を有し、位置情報署名部83は、鍵情報831を有している。
車両8は、認証要求において鍵情報を用いて送信される位置情報に署名を付与して送信し(ステップS63)、ローカルサーバ5では、署名情報の検証が行われ、署名が正しく、かつ受信した車両8の位置情報がローカルサーバ5への切替えが許可された範囲内であるときに、車両8の通信端末81とローカル網基地局6との間での認証・調停を事前に実施する。
そして、その結果、問題が無ければ車両認証応答を行う(ステップS63)。
この構成によれば、認証要求の発生が限定されるので、認証に係る通信量および認証を行うローカルサーバ5の負荷を軽減することができる。
(ローカルサーバの接続元認証)
車両8が正当であることを確認する手段として、実施の形態1とは異なる手段について説明する。
図7に示す情報配信システムにおいては、ローカル網エリア9(私有地)に進入する前の道路にゲート装置10を配置している。
この情報配信システムの動作シーケンス図を図8に示す。
この構成によれば、認証の相手が正しいことを車両情報の一致で確認するので、なりすましによる誤認識を防止することができる。
この構成によれば、車両8から車両認証要求をしていないという誤操作を防ぐことができる。
(ローカル網内の限定情報へのアクセス権付与)
図10は、ローカル網内限定情報へアクセスするためのワンタイムパスワードを用いる例を示す動作シーケンス図である。
車両8とローカルサーバ5との間で、認証を行う際の車両認証応答に、ワンタイムパスワードが含まれており、公衆網エリア7を走行する状態からローカル網エリア9を走行する状態に通信を切り替えた場合に、ローカルサーバ5への接続要求の認証時にワンタイムパスワードを用いて認証を行う。ここで、ワンタイムパスワードは、車両8の位置からローカル網エリア9の入り口までの移動に要すると予測される時間に限って有効に設定されているパスワードである。
この構成によれば、ローカルサーバ5による認証に要する時間を短縮できるのでスムーズに情報を取得することができる。
(地図情報の事前配布)
図11は、ローカルサーバ5が保有している私的地図情報11(狭域地図情報)を、車両8に提供する動作シーケンスを表している。特に、車両8がローカル網エリア9に進入する前に、私的地図情報11を取得して、公道地図情報12と合成することによって、車両8の現在位置から、私有地の入り口を通過して、目的地点までの走行路線を設定する事例を表している。
この構成によれば、エリア進入における課金などの別の目的のために設置されている路側機が存在する場合、この路側機に機能を追加するによって車両8の検出を行うことができる。
この構成によれば、ユーザが利用しないローカル網エリアの情報が、無用に配信されるのを抑止できるので秘匿性が向上する。
この構成によれば、ローカル網エリア9の情報の配信先が予め登録することによって限定されているので、機密情報の漏洩を防ぐための事前策が行われていることから秘匿性が向上する。
この構成によれば、ローカル情報のうち、必要経路のみを配信するので、一時的なユーザに対してその他の秘匿性のある情報へのアクセスを防止できるので秘匿性が向上する。
この構成によれば、ローカル網エリア9から退出した車両8から、私的地図情報を取り出すことが出来なくなるので秘匿性が向上する。
従って、例示されていない無数の変形例が、本願明細書に開示される技術の範囲内において想定される。例えば、少なくとも1つの構成要素を変形する場合、追加する場合または省略する場合、さらには、少なくとも1つの構成要素を抽出し、他の実施の形態の構成要素と組み合わせる場合が含まれるものとする。
