FIG. 2 is a block diagram of the functional configuration of the information processing system according to the embodiment.
　図１に示されるように、実施の形態に係る情報処理システム１０は、施設８０を訪れる訪問者に、施設８０の共同玄関に設けられたオートロック式ドア７０の一時的な解錠権限を付与するためのシステムである。施設８０は、例えば、集合住宅であるが、オフィスビルなどの住宅以外の施設であってもよい。訪問者は、例えば、家事代行サービスの提供事業者から派遣される者、または、荷物の配達員などである。 As shown in FIG. 1, an information processing system 10 according to the embodiment grants a visitor who visits a facility 80 temporary unlocking authority for an auto-locking door 70 provided at the common entrance of the facility 80. It is a system for The facility 80 is, for example, an apartment complex, but may be a facility other than a residence such as an office building. The visitor is, for example, a person dispatched by a housekeeping service provider, or a parcel delivery person.
　情報処理システム１０は、上記一時的な解錠権限を付与するために、ＱＲコード（登録商標）などの二次元コードを使用する。二次元コードは、二次元バーコードなどと呼ばれる場合もある。二次元コードは、従来のバーコード（一次元コード）に比べて情報量が多く、キャッシュレス決済の手段、飛行機の搭乗チケット、または、ロッカーの解錠キーといった用途に利用されている。 The information processing system 10 uses a two-dimensional code such as a QR code (registered trademark) to grant the temporary unlocking authority. A two-dimensional code may also be called a two-dimensional bar code. Two-dimensional codes have a larger amount of information than conventional bar codes (one-dimensional codes), and are used for cashless payment means, airplane boarding tickets, and unlocking keys for lockers.
　二次元コードをオートロック式ドア７０の解錠許可証として利用する場合、二次元コードが施設８０の管理者から発行された正規の許可証であることをオートロック式ドア７０の制御装置６０が検証する必要がある。このような検証を実現するために、一般的には、制御装置６０に新たな解錠許可証が発行されたことを事前登録する必要がある。 When the two-dimensional code is used as a permit for unlocking the auto-locking door 70, the control device 60 of the auto-locking door 70 confirms that the two-dimensional code is a valid permit issued by the manager of the facility 80. need to verify. In order to implement such verification, it is generally necessary to pre-register in the control device 60 that a new unlocking permit has been issued.
　これに対し、情報処理システム１０においては、サーバ証明書を二次元コードに変換し、当該二次元コードを認証に用いることで、制御装置６０への事前登録の省略を図っている。 On the other hand, in the information processing system 10, by converting the server certificate into a two-dimensional code and using the two-dimensional code for authentication, the pre-registration with the control device 60 is omitted.
　以下、情報処理システム１０の具体的な構成について説明する。情報処理システム１０は、通信端末２０と、管理端末３０と、第一情報端末４０と、第二情報端末５０と、制御装置６０と、オートロック式ドア７０とを備える。 A specific configuration of the information processing system 10 will be described below.

The communication terminal 20 displays the two-dimensional code on the display unit 25 when the visitor tries to unlock the auto-locking door 70 . The communication terminal 20 is, for example, a mobile terminal such as a smart phone or a tablet terminal. Communication terminal 20 includes operation reception unit 21 , communication unit 22 , information processing unit 23 , storage unit 24 , and display unit 25 .
　操作受付部２１は、訪問者の操作を受け付ける。操作受付部２１は、例えば、タッチパネルによって実現されるが、ハードウェアキーなどによって実現されてもよい。 The operation reception unit 21 receives a visitor's operation. The operation reception unit 21 is implemented by, for example, a touch panel, but may be implemented by hardware keys or the like.
　通信部２２は、通信端末２０が管理端末３０と通信を行うための通信回路である。通信部２２は、例えば、管理端末３０と、インターネットなどの広域通信ネットワークを通じた無線通信を行う。 The communication unit 22 is a communication circuit for the communication terminal 20 to communicate with the management terminal 30.

　［動作例１］
　次に、情報処理システム１０の動作例１について説明する。図３及び図４は、情報処理システム１０の動作例１のシーケンス図である。以下の動作例１においては、通信端末２０は、施設８０への訪問者によって使用され、管理端末３０は、施設８０の管理者等によって使用されるものとして説明が行われる。 [Operation example 1]
Next, an operation example 1 of the information processing system 10 will be described. 3 and 4 are sequence diagrams of operation example 1 of the information processing system 10. FIG. In the following operation example 1, it is assumed that the communication terminal 20 is used by a visitor to the facility 80 and the management terminal 30 is used by the administrator of the facility 80 or the like.
　まず、図３を参照しながら、通信端末２０の記憶部２４にサーバ証明書を示す二次元コードの二次元コード情報が記憶されるまでの動作について説明する。サーバ証明書は、オートロック式ドア７０の解錠許可証の役割を果たすものである。図３に示されるように、第一情報端末４０の第一記憶部４４には、第一の公開鍵及び第一の秘密鍵が記憶される。第一の公開鍵及び第一の秘密鍵は、例えば、第一情報端末４０に情報処理システム１０用のアプリケーションプログラム（以下、単にアプリとも記載される）をインストールしたときに生成され、第一記憶部４４に記憶される。 First, the operation until the two-dimensional code information of the two-dimensional code indicating the server certificate is stored in the storage unit 24 of the communication terminal 20 will be described with reference to FIG. The server certificate serves as a permit to unlock the auto-locking door 70 . As shown in FIG. 3, the first storage unit 44 of the first information terminal 40 stores a first public key and a first secret key. The first public key and the first private key are generated, for example, when an application program (hereinafter simply referred to as an application) for the information processing system 10 is installed in the first information terminal 40, and stored in the first storage. Stored in unit 44 .
　また、管理端末３０の端末記憶部３３には、第二の公開鍵及び第二の秘密鍵が記憶される。第二の公開鍵及び第二の秘密鍵は、例えば、管理端末３０に情報処理システム１０用のアプリをインストールしたときに端末記憶部３３に記憶される。 In addition, the terminal storage unit 33 of the management terminal 30 stores a second public key and a second secret key. The second public key and the second private key are stored in the terminal storage unit 33 when an application for the information processing system 10 is installed in the management terminal 30, for example.
　まず、第一情報端末４０は、第一記憶部４４に記憶された第一の公開鍵を管理端末３０へ送信する（Ｓ１１）。第一の公開鍵は、例えば、第一情報端末４０の施設（共同玄関）への設置時に行われる初期設定作業の際に、設置者が第一操作受付部４１に対して所定の操作を行うことで管理端末３０へ送信される。第一の公開鍵の管理端末３０への送信方法、及び、第一の公開鍵の送信タイミングは特に限定されない。 First, the first information terminal 40 transmits the first public key stored in the first storage unit 44 to the management terminal 30 (S11). The first public key is obtained, for example, by an installer performing a predetermined operation on the first operation reception unit 41 during initial setting work performed when the first information terminal 40 is installed in a facility (communal entrance). By doing so, it is transmitted to the management terminal 30 . The method of transmitting the first public key to the management terminal 30 and the timing of transmitting the first public key are not particularly limited.
　管理端末３０の端末通信部３１は、第一の公開鍵を受信する。端末制御部３２は、受信した第一の公開鍵を端末記憶部３３に記憶する（Ｓ１２）。 The terminal communication unit 31 of the management terminal 30 receives the first public key. The terminal control unit 32 stores the received first public key in the terminal storage unit 33 (S12).
　その後、訪問者は、施設８０を実際に訪問する前などに、通信端末２０の操作受付部２１へ所定の操作を行う。所定の操作には、パスワードを設定するための設定操作が含まれる。操作受付部２１によって所定の操作が受け付けられると（Ｓ１３）、情報処理部２３は、二次元コードの発行要求を生成し、生成した発行要求を通信部２２に管理端末３０へ送信させる。つまり、通信部２２は、二次元コードの発行要求を管理端末３０へ送信する（Ｓ１４）。なお、通信部２２は、広域通信ネットワークを通じた無線通信により発行要求を管理端末３０へ送信する。発行要求には、訪問者によって設定されたパスワードが含まれる。 After that, the visitor performs a predetermined operation on the operation reception unit 21 of the communication terminal 20 before actually visiting the facility 80 . The prescribed operation includes a setting operation for setting a password. When the operation receiving unit 21 receives a predetermined operation ( S<b>13 ), the information processing unit 23 generates a two-dimensional code issue request and causes the communication unit 22 to transmit the generated issue request to the management terminal 30 . That is, the communication unit 22 transmits a two-dimensional code issue request to the management terminal 30 (S14). The communication unit 22 transmits the issue request to the management terminal 30 by wireless communication through the wide area communication network. The issuance request contains the password set by the visitor.
　管理端末３０の端末通信部３１は、発行要求を受信する。管理者が訪問者の発行要求を確認し、訪問者によるオートロック式ドア７０の解錠を許可する場合、端末制御部３２は、第一サーバ証明書を発行する（Ｓ１５）。端末制御部３２は、具体的には、ステップＳ１１において受信した（ステップＳ１２において端末記憶部３３に記憶された）第一の公開鍵及び利用条件に対する第一署名を第二の秘密鍵を用いて生成し、第一の公開鍵、利用条件、及び、第一署名を含む第一サーバ証明書を発行する。利用条件は、例えば、時期的な条件（言い換えれば、有効期限）を示す情報であり、例えば、管理端末３０を使用する管理者などによってあらかじめ定められる。なお、利用条件は、有効回数に関する条件であってもよい。ここでの有効回数とは、第一サーバ証明書によってオートロック式ドア７０を解錠することができる上限回数を意味する。 The terminal communication unit 31 of the management terminal 30 receives the issue request. When the administrator confirms the visitor's request for issuance and permits the visitor to unlock the auto-locking door 70, the terminal control unit 32 issues the first server certificate (S15). Specifically, the terminal control unit 32 converts the first public key received in step S11 (stored in the terminal storage unit 33 in step S12) and the first signature for the usage conditions using the second secret key. Generate and issue a first server certificate that includes a first public key, terms of use, and a first signature. The usage condition is, for example, information indicating a temporal condition (in other words, an expiration date), and is determined in advance by an administrator who uses the management terminal 30, for example. Note that the usage condition may be a condition related to the valid number of times. Here, the valid number of times means the maximum number of times that the auto-locking door 70 can be unlocked by the first server certificate.
　なお、第一サーバ証明書のフォーマットとしては、例えば、Ｘ．５０９証明書が用いられる。図５は、第一サーバ証明書のフォーマットの一例を示す図である。図５における証明書の有効期間は、上記利用条件（有効期限）に相当し、主体者公開鍵情報は、第一の公開鍵に相当し、ｓｉｇｎａｔｕｒｅＶａｌｕｅは、第一署名に相当する。なお、図５のフォーマットの拡張領域に、有効期限以外の利用条件（有効回数など）が格納されてもよい。 　The format of the first server certificate is, for example, X. 509 certificates are used. FIG. 5 is a diagram showing an example of the format of the first server certificate. The term of validity of the certificate in FIG. 5 corresponds to the usage conditions (term of validity), the subject public key information corresponds to the first public key, and the signatureValue corresponds to the first signature. Note that usage conditions other than the expiration date (such as the number of valid times) may be stored in the extended area of the format in FIG.
　次に、端末制御部３２は、ステップＳ１５において発行した第一サーバ証明書を、ステップＳ１４において受信した発行要求に含まれるパスワードによって暗号化する（Ｓ１６）。第一サーバ証明書をパスワードによって暗号化する方法については既存のどのようなアルゴリズムが用いられてもよく、特に限定されない。 Next, the terminal control unit 32 encrypts the first server certificate issued in step S15 with the password included in the issue request received in step S14 (S16). Any existing algorithm may be used as a method of encrypting the first server certificate with a password, and there is no particular limitation.
　次に、端末制御部３２は、暗号化された第一サーバ証明書を二次元コード化する（Ｓ１７）。つまり、端末制御部３２は、第一の公開鍵、及び、第一署名を含む第一サーバ証明書であって、パスワードによって暗号化された第一サーバ証明書を示す二次元コードを発行する。また、端末制御部３２は、二次元コードを表示するための二次元コード情報を、端末通信部３１に通信端末２０へ送信させる（Ｓ１８）。二次元コード情報は、例えば、電子メールなどによって管理端末３０から通信端末２０へ送信される。 Next, the terminal control unit 32 converts the encrypted first server certificate into a two-dimensional code (S17). That is, the terminal control unit 32 issues a two-dimensional code indicating the first server certificate including the first public key and the first signature, which is encrypted with a password. The terminal control unit 32 also causes the terminal communication unit 31 to transmit two-dimensional code information for displaying the two-dimensional code to the communication terminal 20 (S18). The two-dimensional code information is transmitted from the management terminal 30 to the communication terminal 20 by e-mail, for example.
　通信端末２０の通信部２２は、二次元コード情報を受信する。情報処理部２３は、受信された二次元コード情報を記憶部２４に記憶する（Ｓ１９）。 The communication unit 22 of the communication terminal 20 receives the two-dimensional code information. The information processing section 23 stores the received two-dimensional code information in the storage section 24 (S19).
　次に、図４を参照しながら、二次元コード（第一サーバ証明書）を用いてオートロック式ドア７０が解錠されるまでの動作について説明する。図４に示されるように、制御装置６０の記憶部６３には、ルート証明書が記憶される。ルート証明書には第二の公開鍵が含まれる。ルート証明書は、例えば、管理端末３０の端末制御部３２によって生成され、端末通信部３１によって制御装置６０に送信されることで記憶部６３に記憶される。ルート証明書は、制御装置６０の製造時に製造設備により記憶部６３に記憶されてもよい。 Next, referring to FIG. 4, the operation until the auto-locking door 70 is unlocked using the two-dimensional code (first server certificate) will be described. As shown in FIG. 4, the storage unit 63 of the control device 60 stores a root certificate. A root certificate contains a second public key. The root certificate is generated, for example, by the terminal control unit 32 of the management terminal 30 , transmitted to the control device 60 by the terminal communication unit 31 , and stored in the storage unit 63 . The root certificate may be stored in the storage unit 63 by manufacturing equipment when the control device 60 is manufactured.
　まず、訪問者は、施設８０の周辺に到着すると、第一情報端末４０の近くへ移動し、通信端末２０の操作受付部２１へ所定の操作を行う。情報処理部２３は、受け付けられた所定の操作を契機に、ステップＳ１９において記憶部２４に記憶された二次元コード情報に基づいて二次元コードを表示部２５に表示する（Ｓ２０）。訪問者は、通信端末２０を読取部４６にかざすことにより、表示部２５に表示された二次元コードを第一情報端末４０の読取部４６に提示する。読取部４６は、二次元コードを読み取る（Ｓ２１）。 First, when the visitor arrives near the facility 80 , he moves near the first information terminal 40 and performs a predetermined operation on the operation reception unit 21 of the communication terminal 20 . Triggered by the received predetermined operation, the information processing section 23 displays the two-dimensional code on the display section 25 based on the two-dimensional code information stored in the storage section 24 in step S19 (S20). The visitor presents the two-dimensional code displayed on the display unit 25 to the reading unit 46 of the first information terminal 40 by holding the communication terminal 20 over the reading unit 46 . The reading unit 46 reads the two-dimensional code (S21).
　また、訪問者は、第一情報端末４０の第一操作受付部４１へパスワードの入力操作を行う。第一操作受付部４１は、パスワードの入力操作を受け付ける（Ｓ２２）。ステップＳ２２において入力されるパスワードは、ステップＳ１３において訪問者自身が設定したパスワードである。 Also, the visitor performs a password input operation to the first operation reception unit 41 of the first information terminal 40 . The first operation accepting unit 41 accepts a password input operation (S22). The password entered in step S22 is the password set by the visitor himself in step S13.
　第一操作受付部４１によってパスワードの入力操作が受け付けられると、第一情報処理部４３は、ステップＳ２１において読取部４６を通じて読み取った二次元コード、及び、ステップＳ２２において入力されたパスワードに基づいて、第一サーバ証明書を取得する（Ｓ２３）。第一情報処理部４３は、具体的には、二次元コードを暗号化された第一サーバ証明書に変換し、暗号化された第一サーバ証明書をパスワードによって復号することで第一サーバ証明書を取得する。つまり、第一情報処理部４３は、発行された二次元コードを読み取り、かつ、入力されたパスワードを用いた復号処理を行うことにより、第一サーバ証明書を取得する。 When the password input operation is accepted by the first operation accepting unit 41, the first information processing unit 43, based on the two-dimensional code read by the reading unit 46 in step S21 and the password entered in step S22, A first server certificate is obtained (S23). Specifically, the first information processing unit 43 converts the two-dimensional code into an encrypted first server certificate, and decrypts the encrypted first server certificate with a password to obtain the first server certificate. get the book. That is, the first information processing unit 43 acquires the first server certificate by reading the issued two-dimensional code and performing decryption processing using the input password.
　次に、第一情報処理部４３は、取得した第一サーバ証明書を第一通信部４２に制御装置６０へ送信させる。つまり、第一通信部４２は、サーバ証明書を制御装置６０へ送信する（Ｓ２４）。なお、通信部２２は、局所通信ネットワークを通じた無線通信により、サーバ証明書を制御装置６０へ送信する。この無線通信は、例えば、Ｂｌｕｅｔｏｏｔｈ（登録商標）などの通信規格に基づく近距離無線通信である。 Next, the first information processing section 43 causes the first communication section 42 to transmit the acquired first server certificate to the control device 60 . That is, the first communication unit 42 transmits the server certificate to the control device 60 (S24). Note that the communication unit 22 transmits the server certificate to the control device 60 by wireless communication through the local communication network. This wireless communication is, for example, short-range wireless communication based on a communication standard such as Bluetooth (registered trademark).
　制御装置６０の通信部６１は、第一サーバ証明書を受信する。制御部６２は、受信された第一サーバ証明書に含まれる第一署名を、記憶部６３に記憶されたルート証明書に含まれる第二の公開鍵を用いて検証する（Ｓ２５）。制御部６２は、第一署名の検証に成功した場合に、第一サーバ証明書に含まれている利用条件の判定を行う（Ｓ２６）。上述のように、利用条件は、例えば、時期的な条件であり、制御部６２は、時期的な条件が満たされるか否かを判定する。制御部６２は、時期的な要件が満たされると判定した場合に、第一サーバ証明書に含まれる第一の公開鍵を用いてセッション鍵を生成する（Ｓ２７）。制御部６２は、生成したセッション鍵を第一の公開鍵で暗号化し、暗号化されたセッション鍵を通信部６１に第一情報端末４０へ送信させる（Ｓ２８）。 The communication unit 61 of the control device 60 receives the first server certificate. The control unit 62 verifies the first signature included in the received first server certificate using the second public key included in the root certificate stored in the storage unit 63 (S25). If the verification of the first signature is successful, the control unit 62 determines the terms of use included in the first server certificate (S26). As described above, the usage condition is, for example, a temporal condition, and the control unit 62 determines whether or not the temporal condition is satisfied. When determining that the timing requirements are satisfied, the control unit 62 generates a session key using the first public key included in the first server certificate (S27). The control unit 62 encrypts the generated session key with the first public key, and causes the communication unit 61 to transmit the encrypted session key to the first information terminal 40 (S28).
　第一情報端末４０の第一通信部４２は、暗号化されたセッション鍵を受信する。第一情報処理部４３は、第一の秘密鍵を用いてセッション鍵を復号し、セッション鍵を用いた暗号化通信により、解錠指令を第一通信部４２に制御装置６０へ送信させる（Ｓ２９）。 The first communication unit 42 of the first information terminal 40 receives the encrypted session key. The first information processing unit 43 decrypts the session key using the first secret key, and causes the first communication unit 42 to transmit an unlock command to the control device 60 through encrypted communication using the session key (S29 ).
　制御装置６０の通信部６１は、解錠指令を受信する。制御部６２は、受信された解錠指令に基づいてオートロック式ドア７０を解錠する（Ｓ３０）。制御部６２は、具体的には、オートロック式ドア７０に制御信号を送信することによりオートロック式ドア７０を解錠する。 The communication unit 61 of the control device 60 receives the unlock command. The controller 62 unlocks the auto-locking door 70 based on the received unlock command (S30). Specifically, the control unit 62 unlocks the auto-locking door 70 by transmitting a control signal to the auto-locking door 70 .
　このように、情報処理システム１０においては、管理端末３０は、第一サーバ証明書及びルート証明書を用いて、安全に通信端末２０にオートロック式ドア７０の解錠権限を付与することができる。動作例１のような解錠方法は、訪問者に関する情報をあらかじめ第一情報端末４０または制御装置６０に登録しなくても、訪問者に解錠権限を付与することができる。また、動作例１のような解錠方法によれば、訪問者は通信端末２０にアプリ（公開鍵及び秘密鍵）をインストールする必要がないことから、訪問者への負担が少ない利点がある。 Thus, in the information processing system 10, the management terminal 30 can safely grant the unlocking authority of the auto-locking door 70 to the communication terminal 20 using the first server certificate and the root certificate. . The unlocking method as in Operation Example 1 can give the unlocking authority to the visitor without registering information on the visitor in the first information terminal 40 or the control device 60 in advance. Further, according to the unlocking method as in Operation Example 1, the visitor does not need to install an application (public key and private key) on the communication terminal 20, so there is an advantage that the burden on the visitor is small.
　また、第一情報端末４０及び制御装置６０は、セッション鍵を用いた暗号化通信（無線通信）を行うことから、第一情報端末４０及び制御装置６０を分離して配置したとしても、盗聴などにより第一情報端末４０になりすました他の情報端末が不正にオートロック式ドア７０を解錠することが抑制される。 In addition, since the first information terminal 40 and the control device 60 perform encrypted communication (wireless communication) using a session key, even if the first information terminal 40 and the control device 60 are arranged separately, eavesdropping, etc. Therefore, unauthorized unlocking of the auto-locking door 70 by another information terminal impersonating the first information terminal 40 is suppressed.
　また、第一情報端末４０及び制御装置６０を分離して配置できることによれば、後述の動作例２（居住者によるオートロック式ドア７０の解錠）を実行することができる既存のシステムに、第一情報端末４０を新規に導入することで動作例１（訪問者によるオートロック式ドア７０の解錠）を容易に実現することができる。後述の動作例２で説明されるように、訪問者が通信端末２０を使用してオートロック式ドア７０を解錠する場合、及び、居住者が第二情報端末５０を使用してオートロック式ドア７０を解錠する場合も制御装置６０が行う処理は共通化されている。この点からも、情報処理システム１０は、既存のシステムに第一情報端末４０を新規に導入することで動作例１を容易に実現することができる。 In addition, according to the fact that the first information terminal 40 and the control device 60 can be arranged separately, the existing system that can execute the later-described operation example 2 (unlocking the auto-locking door 70 by the resident) By newly introducing the first information terminal 40, operation example 1 (unlocking of the auto-locking door 70 by the visitor) can be easily realized. As described in Operation Example 2 below, when the visitor uses the communication terminal 20 to unlock the auto-locking door 70, and when the resident uses the second information terminal 50 to open the auto-locking When unlocking the door 70, the processing performed by the control device 60 is also shared. Also from this point, the information processing system 10 can easily implement the operation example 1 by newly introducing the first information terminal 40 into the existing system.
　なお、動作例１では、二次元コードは通信端末２０の表示部２５に表示されたが、訪問者は、二次元コードを印刷した紙を施設８０に持参し、これを読取部４６に提示することによっても、オートロック式ドア７０を解錠することができる。 In operation example 1, the two-dimensional code was displayed on the display unit 25 of the communication terminal 20, but the visitor brings a piece of paper on which the two-dimensional code is printed to the facility 80 and presents it to the reading unit 46. This also allows the auto-locking door 70 to be unlocked.
　また、動作例１においてパスワードを使用することは必須ではないが、パスワードが使用されることで訪問者以外の第三者が二次元コードを使用してオートロック式ドア７０を解錠することを抑制することができる。動作例１では、パスワードは訪問者によって設定されたが、管理者によって設定されて訪問者に通知されてもよい。 In addition, although it is not essential to use a password in Operation Example 1, the use of the password prevents a third party other than the visitor from unlocking the auto-locking door 70 using the two-dimensional code. can be suppressed. Although the password is set by the visitor in Operation Example 1, it may be set by the administrator and notified to the visitor.
　［動作例２］
　次に、情報処理システム１０の動作例２について説明する。図６及び図７は、情報処理システム１０の動作例２のシーケンス図である。以下の動作例２においては、第二情報端末５０は、施設８０の専有部８２の居住者によって使用され、管理端末３０は、施設８０の管理者等によって使用されるものとして説明が行われる。 [Operation example 2]
Next, an operation example 2 of the information processing system 10 will be described. 6 and 7 are sequence diagrams of operation example 2 of the information processing system 10. FIG. In the following operation example 2, it is assumed that the second information terminal 50 is used by the resident of the exclusive area 82 of the facility 80 and the management terminal 30 is used by the manager of the facility 80 or the like.
　まず、図６を参照しながら、第二情報端末５０の第二記憶部５４に第二サーバ証明書が記憶されるまでの動作について説明する。第二サーバ証明書は、オートロック式ドア７０の解錠許可証の役割を果たすものである。図６に示されるように、第二情報端末５０の第二記憶部５４には、第三の公開鍵及び第三の秘密鍵が記憶される。第三の公開鍵及び第三の秘密鍵は、例えば、第二情報端末５０に情報処理システム１０用のアプリをインストールしたときに生成され、第二記憶部５４に記憶される。また、動作例１と同様に、管理端末３０の端末記憶部３３には、第二の公開鍵及び第二の秘密鍵が記憶される。 First, the operation until the second server certificate is stored in the second storage unit 54 of the second information terminal 50 will be described with reference to FIG. The second server certificate serves as a permit to unlock the auto-locking door 70 . As shown in FIG. 6, the second storage unit 54 of the second information terminal 50 stores a third public key and a third private key. The third public key and the third private key are generated, for example, when an application for the information processing system 10 is installed in the second information terminal 50 and stored in the second storage unit 54 . Also, as in the first operation example, the terminal storage unit 33 of the management terminal 30 stores a second public key and a second secret key.
　まず、居住者は、上記アプリを実行中の第二情報端末５０の第二操作受付部５１へ所定の操作を行う。所定の操作は、第二サーバ証明書をインストールするための操作である。第二操作受付部５１は、所定の操作を受け付ける（Ｓ３１）。 First, the resident performs a predetermined operation on the second operation reception unit 51 of the second information terminal 50 running the above application. The predetermined operation is an operation for installing the second server certificate. The second operation accepting unit 51 accepts a predetermined operation (S31).
　第二操作受付部５１によって所定の操作が受け付けられると、第二情報処理部５３は、第二サーバ証明書の発行要求を生成し、生成した発行要求を第二通信部５２に管理端末３０へ送信させる。発行要求には、第三の公開鍵が含まれる。つまり、第二通信部５２は、第三の公開鍵を管理端末３０へ送信する（Ｓ３２）。なお、第二通信部５２は、広域通信ネットワークを通じた無線通信により第三の公開鍵を管理端末３０へ送信する。 When the second operation receiving unit 51 receives a predetermined operation, the second information processing unit 53 generates a second server certificate issuance request, and sends the generated issuance request to the second communication unit 52 to the management terminal 30. send. The issuance request includes the third public key. That is, the second communication unit 52 transmits the third public key to the management terminal 30 (S32). The second communication unit 52 transmits the third public key to the management terminal 30 by wireless communication through the wide area communication network.
　管理端末３０の端末通信部３１は、第三の公開鍵を含む発行要求を受信する。管理者が居住者の発行要求を確認し、居住者によるオートロック式ドア７０の解錠を許可する場合、端末制御部３２は、受信した第三の公開鍵及び利用条件に対する第二署名を第二の秘密鍵を用いて生成する（Ｓ３３）。また、端末制御部３２は、第三の公開鍵、利用条件、及び、第二署名を含む第二サーバ証明書を、端末通信部３１に第二情報端末５０へ送信させる（Ｓ３４）。利用条件は、例えば、時期的な条件（言い換えれば、有効期限）を示す情報であり、例えば、管理端末３０を使用する管理者などによってあらかじめ定められる。なお、利用条件は、有効回数に関する条件であってもよい。ここでの有効回数とは、第二サーバ証明書によってオートロック式ドア７０を解錠することができる上限回数を意味する。 The terminal communication unit 31 of the management terminal 30 receives the issue request including the third public key. When the administrator confirms the resident's issuance request and permits the resident to unlock the auto-locking door 70, the terminal control unit 32 sends the received third public key and the second signature for the usage conditions to the third public key. It is generated using the second secret key (S33). In addition, the terminal control unit 32 causes the terminal communication unit 31 to transmit the second server certificate including the third public key, the terms of use, and the second signature to the second information terminal 50 (S34). The usage condition is, for example, information indicating a temporal condition (in other words, an expiration date), and is determined in advance by an administrator who uses the management terminal 30, for example. Note that the usage condition may be a condition related to the valid number of times. Here, the valid number of times means the maximum number of times that the auto-locking door 70 can be unlocked by the second server certificate.
　なお、第二サーバ証明書のフォーマットとしては、例えば、Ｘ．５０９証明書（図５）が用いられる。図５における証明書の有効期間は、上記利用条件に相当し、主体者公開鍵情報は、第三の公開鍵に相当し、ｓｉｇｎａｔｕｒｅＶａｌｕｅは、第二署名に相当する。なお、図５のフォーマットの拡張領域に、有効期限以外の利用条件（有効回数など）が格納されてもよい。 　The format of the second server certificate is, for example, X. An H.509 certificate (FIG. 5) is used. The validity period of the certificate in FIG. 5 corresponds to the usage conditions, the subject public key information corresponds to the third public key, and the signatureValue corresponds to the second signature. Note that usage conditions other than the expiration date (such as the number of valid times) may be stored in the extended area of the format in FIG.
　第二情報端末５０の第二通信部５２は、第二サーバ証明書を受信する。第二情報処理部５３は、受信された第二サーバ証明書を第二記憶部５４に記憶する（Ｓ３５）。 The second communication unit 52 of the second information terminal 50 receives the second server certificate. The second information processing unit 53 stores the received second server certificate in the second storage unit 54 (S35).
　次に、図７を参照しながら、第二サーバ証明書を用いてオートロック式ドア７０が解錠されるまでの動作について説明する。図７に示されるように、制御装置６０の記憶部６３には、ルート証明書が記憶される。ルート証明書には第二の公開鍵が含まれる。ルート証明書は、例えば、管理端末３０の端末制御部３２によって生成され、端末通信部３１によって制御装置６０に送信されることで記憶部６３に記憶される。ルート証明書は、制御装置６０の製造時に製造設備により記憶部６３に記憶されてもよい。 Next, referring to FIG. 7, the operation until the auto-locking door 70 is unlocked using the second server certificate will be described. As shown in FIG. 7, the storage unit 63 of the control device 60 stores a root certificate. A root certificate contains a second public key. The root certificate is generated, for example, by the terminal control unit 32 of the management terminal 30 , transmitted to the control device 60 by the terminal communication unit 31 , and stored in the storage unit 63 . The root certificate may be stored in the storage unit 63 by manufacturing equipment when the control device 60 is manufactured.
　まず、居住者は、施設８０へ到着するとオートロック式ドア７０の近くへ移動し、上記アプリを実行中の第二情報端末５０の第二操作受付部５１へオートロック式ドア７０を解錠するための所定の解錠操作を行う。第二操作受付部５１は、解錠操作を受け付ける（Ｓ３６）。 First, when the resident arrives at the facility 80, the resident moves near the auto-locking door 70, and unlocks the auto-locking door 70 to the second operation reception unit 51 of the second information terminal 50 running the above application. perform a predetermined unlocking operation for The second operation accepting unit 51 accepts an unlocking operation (S36).
　第二操作受付部５１によって解錠操作が受け付けられると、第二情報処理部５３は、第二サーバ証明書を第二通信部５２に制御装置６０へ送信させる。つまり、第二通信部５２は、第二サーバ証明書を制御装置６０へ送信する（Ｓ３７）。なお、第二通信部５２は、局所通信ネットワークを通じた無線通信により、第二サーバ証明書を制御装置６０へ送信する。この無線通信は、例えば、Ｂｌｕｅｔｏｏｔｈ（登録商標）などの通信規格に基づく近距離無線通信である。 When the unlocking operation is accepted by the second operation accepting unit 51 , the second information processing unit 53 causes the second communication unit 52 to transmit the second server certificate to the control device 60 . That is, the second communication unit 52 transmits the second server certificate to the control device 60 (S37). The second communication unit 52 transmits the second server certificate to the control device 60 by wireless communication through the local communication network. This wireless communication is, for example, short-range wireless communication based on a communication standard such as Bluetooth (registered trademark).
　制御装置６０の通信部６１は、第二サーバ証明書を受信する。制御部６２は、受信された第二サーバ証明書に含まれる第二署名を、記憶部６３に記憶されたルート証明書に含まれる第二の公開鍵を用いて検証する（Ｓ３８）。制御部６２は、第二署名の検証に成功した場合に、第二サーバ証明書に含まれている利用条件の判定を行う（Ｓ３９）。上述のように、利用条件は、例えば、時期的な条件であり、制御部６２は、時期的な条件が満たされるか否かを判定する。制御部６２は、時期的な要件が満たされると判定した場合に、第二サーバ証明書に含まれる第三の公開鍵を用いてセッション鍵を生成する（Ｓ４０）。制御部６２は、生成したセッション鍵を第三の公開鍵で暗号化し、暗号化されたセッション鍵を通信部６１に第二情報端末５０へ送信させる（Ｓ４１）。 The communication unit 61 of the control device 60 receives the second server certificate. The control unit 62 verifies the second signature included in the received second server certificate using the second public key included in the root certificate stored in the storage unit 63 (S38). If the verification of the second signature is successful, the control unit 62 determines the terms of use included in the second server certificate (S39). As described above, the usage condition is, for example, a temporal condition, and the control unit 62 determines whether or not the temporal condition is satisfied. The control unit 62 generates a session key using the third public key included in the second server certificate when determining that the timing requirements are satisfied (S40). The control unit 62 encrypts the generated session key with the third public key, and causes the communication unit 61 to transmit the encrypted session key to the second information terminal 50 (S41).
　第二情報端末５０の第二通信部５２は、暗号化されたセッション鍵を受信する。第二情報処理部５３は、第三の秘密鍵を用いてセッション鍵を復号し、セッション鍵を用いた暗号化通信により、解錠指令を第二通信部５２に制御装置６０へ送信させる（Ｓ４２）。 The second communication unit 52 of the second information terminal 50 receives the encrypted session key. The second information processing unit 53 decrypts the session key using the third secret key, and causes the second communication unit 52 to transmit an unlock command to the control device 60 through encrypted communication using the session key (S42 ).
　制御装置６０の通信部６１は、解錠指令を受信する。制御部６２は、受信された解錠指令に基づいてオートロック式ドア７０を解錠する（Ｓ４３）。制御部６２は、具体的には、オートロック式ドア７０に制御信号を送信することによりオートロック式ドア７０を解錠する。なお、第二情報端末５０は、同様の動作シーケンスに基づいて、オートロック式ドア７０の施錠を行うこともできる。 The communication unit 61 of the control device 60 receives the unlock command. The control unit 62 unlocks the auto-locking door 70 based on the received unlocking command (S43). Specifically, the control unit 62 unlocks the auto-locking door 70 by transmitting a control signal to the auto-locking door 70 . The second information terminal 50 can also lock the auto-locking door 70 based on the same operation sequence.
　このように、情報処理システム１０においては、管理端末３０は、第二サーバ証明書及び第二ルート証明書を用いて、安全に第二情報端末５０にオートロック式ドア７０の解錠権限を付与することができる。 As described above, in the information processing system 10, the management terminal 30 uses the second server certificate and the second root certificate to safely grant the second information terminal 50 the authority to unlock the auto-locking door 70. can do.
　［変形例］
　上記実施の形態では、利用条件がサーバ証明書（第一サーバ証明書または第二サーバ証明書）に含まれたが、利用条件は、サーバ証明書とは別に安全な方法で通信端末２０から制御装置６０へ送信されてもよい。例えば、図４でステップＳ２８よりも後に、セッション鍵を用いた暗号通信によって、利用条件が管理端末３０の第一署名と共に第一情報端末４０から制御装置６０へ送信されてもよい。また、図７でステップＳ４１よりも後にセッション鍵を用いた暗号化通信によって利用条件が管理端末３０の第二署名と共に第二情報端末５０から制御装置６０へ送信されてもよい。このように、サーバ証明書と利用条件を分けることにより、サーバ証明書の再発行をしなくても利用条件を柔軟に追加または変更することが可能となる。 [Modification]
In the above embodiment, the terms of use are included in the server certificate (the first server certificate or the second server certificate), but the terms of use are controlled from the communication terminal 20 in a secure manner separately from the server certificate. It may be transmitted to device 60 . For example, after step S28 in FIG. 4, the terms of use may be transmitted from the first information terminal 40 to the control device 60 together with the first signature of the management terminal 30 through encrypted communication using a session key. Further, after step S41 in FIG. 7, the usage conditions may be transmitted from the second information terminal 50 to the control device 60 together with the second signature of the management terminal 30 by encrypted communication using the session key. By separating the server certificate and the usage conditions in this way, it is possible to flexibly add or change the usage conditions without reissuing the server certificate.
　また、上記実施の形態では、制御装置６０は、オートロック式ドア７０などの施設８０内の空間への人の出入りを制限する機器を制御したが、物品の出入りを制限する機器を制御してもよい。例えば、制御装置６０は、宅配ボックス、コインロッカー、または、貸金庫などの扉を施錠及び解錠する電気錠を制御してもよい。つまり、制御装置６０は、空間に対する物品または人の出入りを制限する機器を制御すればよい。 In the above embodiment, the control device 60 controls devices such as the auto-locking door 70 that restrict people from entering and exiting the space in the facility 80, but controls devices that restrict articles from entering and exiting. good too. For example, the control device 60 may control an electric lock that locks and unlocks the door of a delivery box, coin locker, safe deposit box, or the like. In other words, the control device 60 may control a device that restricts the entry and exit of goods or people into and out of the space.
　また、情報処理システム１０は、空間に対する物品または人の出入りを制限する機器だけでなく、照明機器及び空調機器などの家電機器の制御を特定の人にのみ許可する場合にも適用できる。 In addition, the information processing system 10 can be applied not only to equipment that restricts the entry and exit of goods or people into and out of a space, but also to the case of permitting only a specific person to control home appliances such as lighting equipment and air conditioning equipment.
　［効果等］
　以上説明したように、情報処理システム１０は、空間に対する物品または人の出入りを制限する機器の制限を解除するために用いられる。情報処理システム１０は、第一情報端末４０、管理端末３０、及び、制御装置６０を備える。第一情報端末４０は、第一の秘密鍵及び第一の公開鍵がされた第一記憶部４４と、第一の公開鍵を管理端末３０へ送信する第一通信部４２とを有する。管理端末３０は、第二の秘密鍵及び第二の公開鍵が記憶された端末記憶部３３と、第一情報端末４０から第一の公開鍵を受信する端末通信部３１と、受信された第一の公開鍵に対する第一署名を第二の秘密鍵を用いて生成し、第一の公開鍵、及び、第一署名を含む第一サーバ証明書を示す二次元コードを発行する端末制御部３２とを有する。第一情報端末４０は、管理端末３０によって発行された二次元コードを読み取る読取部４６と、読取部４６が読み取った二次元コードにより、第一サーバ証明書を取得する第一情報処理部４３を有する。第一通信部４２は、取得された第一サーバ証明書を制御装置６０へ送信する。制御装置６０は、第二の公開鍵を含むルート証明書が記憶された記憶部６３と、第一情報端末４０から第一サーバ証明書を受信する通信部６１と、受信された第一サーバ証明書に含まれる第一署名を記憶部６３に記憶されたルート証明書に含まれる第二の公開鍵を用いて検証し、検証に成功した場合に機器の制限を解除する制御部６２とを有する。なお、空間は、例えば、施設８０内の任意の閉空間である。 [Effects, etc.]
As described above, the information processing system 10 is used to release restrictions on devices that restrict the entry and exit of goods or people into and out of space.

The first communication unit 42 transmits the acquired first server certificate to the control device 60 . The control device 60 includes a storage unit 63 storing a root certificate including the second public key, a communication unit 61 receiving the first server certificate from the first information terminal 40, and the received first server certificate. a control unit 62 that verifies the first signature contained in the certificate using the second public key contained in the root certificate stored in the storage unit 63, and cancels the restriction of the device if the verification is successful. . Note that the space is, for example, any closed space within the facility 80 .
　このような情報処理システム１０は、第一サーバ証明書を示す二次元コードの提示を要件として、比較的安全に物品または人の出入りの制限を解除することができる。 Such an information processing system 10 can release restrictions on the entry and exit of goods or people in a relatively safe manner on the condition that a two-dimensional code indicating the first server certificate is presented.
　また、例えば、二次元コードは、パスワードによって暗号化された第一サーバ証明書を示す。第一情報端末４０は、パスワードの入力操作を受け付ける第一操作受付部４１を備える。第一情報処理部４３は、発行された二次元コードを読み取り、かつ、入力されたパスワードを用いた復号処理を行うことにより、第一サーバ証明書を取得する。 Also, for example, the two-dimensional code indicates the first server certificate encrypted with a password. The first information terminal 40 includes a first operation reception unit 41 that receives a password input operation. The first information processing unit 43 acquires the first server certificate by reading the issued two-dimensional code and performing decryption processing using the input password.
