|

|
|
|
|||
|
|
<p>La Radio Identification, ou RFID (en anglais Radio Frequency Identification) est une technologie permettant d’identifier et caractériser un objet grâce à une étiquette émettant des ondes radio.</p>
|
|||
|
|
|
|||
|
|
<p>La RFID fait partie des technologies de localisation en temps réel (RTLS : Real Time Localisation System) et est utilisée principalement dans le cadre du traçage de marchandises dans de nombreux secteurs : retail, santé, transport et logistique, militaire et automobile.</p>
|
|||
|
|
|
|||
|
|
<p>Ainsi, le NFC est un dérivé de la technologie RFID mais présente quelques spécificités. La différence principale entre la RFID et le NFC réside dans le fait que la technologie NFC permet un transfert de données limité. Enfin, la technologie NFC fonctionne à très faible distance, quelques centimètres seulement contre plusieurs mètres pour la RFID.</p>
|
|||
|
|
|
|||
|
|
<p>Qu’est-ce que la technologie RFID et comment fonctionne-t-elle?</p>
|
|||
|
|
|
|||
|
|
<p>Le système d’ identification par radiofréquence comprend deux composants principaux: un transpondeur/étiquette attaché à un objet à identifier et un émetteur-récepteur également appelé interrogateur/lecteur.</p>
|
|||
|
|
|
|||
|
|
<p><img src="/images/How-RFID-Technology-Works-Reader-Writer-System-Tag-Communication.jpg" alt="" width="600" /></p>
|
|||
|
|
|
|||
|
|
<p>Un lecteur se compose d’un module radiofréquence et d’une antenne générant un champ électromagnétique haute fréquence. D’autre part, l’étiquette est généralement un périphérique passif, ce qui signifie qu’elle ne contient pas de batterie. Au lieu de cela, il contient une puce qui stocke et traite les informations, ainsi qu’une antenne pour recevoir et transmettre un signal.</p>
|
|||
|
|
|
|||
|
|
<p>Pour lire les informations encodées sur une étiquette, celle-ci est placée à proximité du lecteur (il n’est pas nécessaire que celle-ci se trouve dans la ligne de vue directe du lecteur). Un lecteur génère un champ électromagnétique qui fait que les électrons se déplacent à travers l’antenne de l’étiquette et alimentent ensuite la puce.</p>

<source src="/files/Passive-RFID-System-Working.mp4" type="video/mp4" />
|
|||
|
|
</video>
|
|||
|
|
|
|||
|

<p>La puce alimentée à l’intérieur de l’étiquette répond ensuite en renvoyant ses informations stockées au lecteur sous la forme d’un autre signal radio. Ceci s’appelle la rétrodiffusion. La rétrodiffusion, ou la modification de l’onde électromagnétique / RF, est détectée et interprétée par le lecteur qui envoie ensuite les données à un ordinateur ou à un microcontrôleur.</p>

|
|||
|
|
|
|||
|
|
<p>Pour pouvoir écrire sur une puce RFID, il faut en posséder les clés de chiffrement. Une sorte de mot de passe qui permet d’encoder et de décoder les informations de la puce. Ces clés de chiffrements vont être stockées avec le contenu de la clé, dans un fichier. Ce fichier nous servira lors de l’étape finale pour copier les données de la puce originale sur la puce chinoise.</p>
|
|||
|
|
|
|||
|
|
<p>Pour lancer l’extraction des clés de chiffrement, placez votre puce sur le lecteur et saisissez dans un terminal la commande suivante.</p>
|
|||
|
|
|
|||
|
|
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo mfoc -P 500 -O carte-vierge.dmp
|
|||
|
|
</code></pre></div></div>
|
|||
|
|
|
|||
|
|
<p>Les clés de chiffrement seront stockées dans le fichier « carte-vierge.dmp ».</p>
|
|||
|
|
|
|||
|
|
<h3 id="copiez-le-contenu-de-la-puce-rfid-dorigine-dans-un-fichier">Copiez le contenu de la puce RFID d’origine dans un fichier</h3>
|
|||
|
|
|
|||
|
|
<p>Maintenant que les clés de chiffrement de la puce chinoise sont extraites, il va falloir faire de même avec la puce originale. Cette opération va copier les clés de chiffrement et le contenu de la puce d’origine dans un fichier. Ce fichier contiendra toutes les données de la puce, ainsi que son UID. C’est en quelques sorte une « sauvegarde » de votre puce RFID. N’hésitez pas à la conserver en lieu sûr, ainsi si vous perdez votre puce RFID vous pourrez en créer de nouvelles à l’identique à partir de ce fichier de sauvegarde.</p>
|
|||
|
|
|
|||
|
|
<p>Pour ce faire, placez la puce originale sur votre lecteur, et entrez la commande suivante :</p>
|
|||
|
|
|
|||
|
|
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo mfoc -P 500 -O carte-originale.dmp
|
|||
|
|
</code></pre></div></div>
|
|||
|
|
|
|||
|
|
<p>Vous l’aurez surement compris, cette commande va créer un fichier « carte-originale.dmp » c’est le fameux fichier de sauvegarde de votre puce originale.</p>
|
|||
|
|
|
|||
|
|
<h3 id="ecrire-le-contenu-de-la-puce-originale-sur-la-puce-vierge">Ecrire le contenu de la puce originale sur la puce vierge</h3>
|
|||
|
|
|
|||
|
|
<p>On arrive au bout ! Vous n’êtes plus qu’à une dernière commande de la victoire ! Maintenant que l’on possède une copie du contenu de la puce originale, ainsi que les clés de chiffrement de la puce chinoise, nous allons pouvoir transférer le contenu et l’UID de la puce originale sur la puce chinoise.</p>
|
|||
|
|
|
|||
|
|
<p>Pour se faire, et toujours dans le terminal, saisissez la commande suivante.</p>
|
|||
|
|
|
|||
|
|
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo nfc-mfclassic W a carte-originale.dmp carte-vierge.dmp
|

|
|
</code></pre></div></div>
|
|||
|
|
|
|||
|
|
<p><img src="/images/nfc-write.png" alt="" /><br />
|
|||
|
|
L’opération devrait prendre 1 grosse seconde avant d’aboutir sur un message de succès. Si vous êtes attentifs, vous remarquerez que la seule différence par rapport au précédent article est le fait que le « W » est écrit en capital. ça n’est pas une erreur, cela demande au lecteur de transférer le contenu de la puce ainsi que le bloc 0 qui contient l’UID. En cas de succès, un message devrait vous confirmer l’écriture de 64 secteurs sur 64</p>

<li><strong><em>VCC</em></strong> alimente le module. Cela peut être n’importe où de 2,5 à 3,3 volts. Vous pouvez le connecter à la sortie 3.3V de votre Arduino. N’oubliez pas que le connecter à une broche 5V détruira probablement votre module!</li>
|
|||
|
|
<li><strong><em>RST</em></strong> est une entrée pour la réinitialisation et la mise hors tension. Lorsque cette broche devient faible, la mise hors tension matérielle est activée. Cela désactive tous les récepteurs de courant internes, y compris l’oscillateur et les broches d’entrée, sont déconnectés du monde extérieur. Sur le front montant, le module est réinitialisé.</li>

<h3 id="les-ports-gpio-du-rasberry-pi">Les ports GPIO du Rasberry Pi</h3>
|

|
|
|

|
|
<p>Un port GPIO transmet un signal relativement binaire (pas de courant ou du courant). Dans le cas de la Raspberry Pi, les ports GPIO travaillent en 3.3 V et environ 20 mA.<br />
|
|||
|
|
Les ports GPIO sont donc un moyen simple de communiquer ou de contrôler des éléments physiques.</p>
|

<p>Les modèles les plus récents de la Raspberry Pi disposent de 40 connectiques GPIO, qui se divisent en différentes catégories avec des usages spécifiques.</p>

<p>Maintenant que nous pouvons lire l’identifiant unique d’un badge, il ne nous reste plus qu’à adapter le code précédent pour comparer l’identifiant lu à un identifiant écrit dans le programme.<br />
|

Nous allons donc modifier un peu le programme précédent pour qu’il compare l’uid lu à celui écris dans le programme, et allumer la led rouge ou verte selon le résultat.<br />
|

Copiez donc le fichier précédent, dans un nouveau fichier <strong>verify_rfid.py</strong> et modifier le pour le code ci-dessous</p>

<h3 id="interfacer-le-module-rfid-rc522-avec-arduino">Interfacer le module RFID RC522 avec Arduino</h3>
|
|||
|
|
|
|||
|
|
<p>Pour commencer, connectez la broche VCC du module à 3,3 V sur l’Arduino et la broche GND à la terre. La broche RST peut être connectée à n’importe quelle broche numérique sur l’Arduino. Dans notre cas, il est connecté à la broche numérique n ° 5. La broche IRQ n’est pas connectée car la bibliothèque Arduino que nous allons utiliser ne la prend pas en charge.<br />
|
|||
|
|
Nous en sommes maintenant aux broches utilisées pour la communication SPI. Comme le module RC522 nécessite beaucoup de transfert de données, il donnera les meilleures performances lorsqu’il est connecté aux broches SPI matérielles d’un microcontrôleur. Les broches SPI matérielles sont beaucoup plus rapides que le “bit-bang” du code d’interface à l’aide d’un autre ensemble de broches.</p>
|
|||
|
|
|
|||
|
|
<blockquote>
|
|||
|
|
<p>Notez que chaque carte Arduino a différentes broches SPI qui doivent être connectées en conséquence. Pour les cartes Arduino telles que UNO / Nano V3.0, ces broches sont numériques 13 (SCK), 12 (MISO), 11 (MOSI) et 10 (SS).</p>
|
|||
|
|
</blockquote>
|
|||
|
|
|
|||
|
|
<p>Si vous avez un Mega, les pins sont différents! Vous voudrez utiliser les technologies numériques 50 (MISO), 51 (MOSI), 52 (SCK) et 53 (SS). Reportez-vous au tableau ci-dessous pour une compréhension rapide.</p>

|
|||
|
|
|
|||
|
|
<p>Communiquer avec le module RFID RC522 est un travail fastidieux, mais heureusement pour nous, il existe une bibliothèque appelée bibliothèque MFRC522 qui simplifie la lecture et l’écriture sur les étiquettes RFID. Merci à Miguel Balboa. Commencez par télécharger la bibliothèque en visitant le <a href="https://github.com/miguelbalboa/rfid">dépôt GitHub</a> ou <a href="https://lastminuteengineers.com/libraries/rfid-master.zip">télécharger le zip</a>:</p>
|
|||
|
|
|
|||
|
|
<p>Pour l’installer, ouvrez l’EDI Arduino, accédez à Esquisse> Inclure la bibliothèque> Ajouter une bibliothèque .ZIP, puis sélectionnez le fichier rfid-master.zip que vous venez de télécharger. Si vous avez besoin de plus de détails sur l’installation d’une bibliothèque, consultez ce tutoriel sur l’installation d’une bibliothèque Arduino .</p>
|
|||
|
|
|
|||
|
|
<p>Une fois la bibliothèque installée, ouvrez le sous-menu Exemples et sélectionnez MFRC522> DumpInfo, exemple d’esquisse.<br />
|
|||
|
|
<img src="/images/MFRC522-Library-Sketch-DumpInfo.png" alt="" width="400" /><br />
|
|||
|
|
Cette esquisse n’écrira aucune donnée sur la balise. Il vous indique simplement s’il a réussi à lire la balise et affiche des informations à ce sujet. Cela peut être très utile avant d’essayer un nouveau tag!</p>
|
|||
|
|
|
|||
|
|
<p>Allez au début de l’esquisse et assurez-vous que le RST_PIN est correctement initialisé. Dans notre cas, nous utilisons la broche numérique 5 alors changez-le en 5!<br />
|
|||
|
|
<img src="/images/MFRC522-Library-Sketch-DumpInfo-RST-pin.png" alt="" width="400" /> <br />
|
|||
|
|
OK, chargez maintenant le croquis et ouvrez le moniteur de série. Dès que vous rapprochez le tag du module, vous obtiendrez probablement le résultat suivant. Ne déplacez pas le tag tant que toutes les informations ne sont pas affichées.<br />
|
|||

Il affiche toutes les informations utiles sur la balise, y compris son identifiant unique (UID), sa taille et 1K de mémoire.</p>

<h3 id="disposition-de-la-mémoire-mifare-classic-1k">Disposition de la mémoire MIFARE Classic 1K</h3>
|
|||
|
|
|
|||
|
|
<p>La mémoire 1K de la balise est organisée en <strong>16 secteurs</strong> (de 0 à 15) Chaque secteur est divisé en <strong>4 blocs</strong> (blocs 0 à 3). Chaque bloc peut stocker 16 octets de données (de 0 à 15).</p>
|
|||
|
|
|
|||
|
|
<p>Cela nous dit sûrement que nous avons<br />
|
|||
|
|
16 secteurs x 4 blocs x 16 octets de données = 1024 octets = 1K de mémoire</p>
|
|||
|
|
|
|||
|
|
<p>L’ensemble de la mémoire 1K avec les secteurs, les blocs et les données est mis en évidence ci-dessous.<br />

<em>Représentation 3D de la disposition de la carte mémoire MIFARE Classic 1K</em></p>
|
|||
|
|
|
|||
|
|
<p>Le bloc 3 de chaque secteur est appelé <strong>secteur</strong> et contient des informations appelées <strong>bits d’accès</strong> permettant d’accorder un <strong>accès</strong> en lecture et en écriture aux blocs restants d’un secteur. Cela signifie que seuls les 3 derniers blocs (blocs 0, 1 et 2) de chaque secteur sont réellement disponibles pour le stockage de données, ce qui signifie que nous avons 48 octets par secteur de 64 octets disponibles pour notre propre usage.</p>
|
|||
|
|
|
|||
|
|
<p>De plus, le bloc 0 du secteur 0 est connu sous le nom de fabricant. Le fabricant contient les données du fabricant du circuit intégré, ainsi que l’ <strong>identificateur unique (UID)</strong>. Le bloc fabricant est surligné en rouge ci-dessous.<br />

<blockquote>
|
|||
|
|
<p><strong>ATTENTION Il est très risqué d’écraser le bloc du fabricant (Manufacturer Block), cela pourrait verrouiller définitivement la carte.</strong></p>

<p>Ensuite, nous devons définir un bloc dans lequel nous allons stocker nos données. Ici le secteur 0 bloc 2 est sélectionné. N’oubliez pas de ne jamais sélectionner le bloc 3 d’un secteur. L’écriture dans un bloc ‘segment de secteur’ peut rendre le bloc inutilisable.</p>

<p>Ensuite, nous définissons un tableau de 16 octets nommé blockcontent[16] qui contient le message que nous voulons écrire dans le bloc. Vous pouvez supprimer n’importe quel bloc en écrivant des zéros.</p>

<p>Ensuite, nous devons définir un tableau de 18 octets nommé readbackblock [18] . Ceci peut être utilisé pour lire le contenu écrit. Attendez… 18 octets? Cela ne devrait-il pas être 16 octets? La réponse est non. La méthode MIFARE_Read de la bibliothèque MFRC522 nécessite un tampon d’au moins 18 octets pour contenir les 16 octets d’un bloc.</p>

<p>Dans la fonction Setup: nous initialisons les communications série avec le PC, la bibliothèque SPI et l’objet MFRC522. Nous devons également préparer la clé de sécurité pour les fonctions de lecture et d’écriture. Ici, les six octets de clé sont définis sur 0xFF. Comme les cartes du kit sont neuves et que les clés n’ont jamais été définies, elles sont 0xFF. Si nous avions une carte programmée par quelqu’un d’autre, nous aurions besoin de connaître la clé pour pouvoir y accéder. Cette clé devrait alors être stockée dans «clé» à la place.</p>

<p>Il est maintenant très facile d’écrire le bloc, il suffit d’appeler une fonction personnalisée appelée writeBlock() qui prend deux paramètres - l’un est le numéro de bloc sur lequel nous souhaitons écrire les données et les données elles-mêmes.</p>

<p>Pour vérifier si l’opération d’écriture a réussi, nous devons relire le contenu du bloc. Cela peut être fait en utilisant la fonction personnalisée appelée readBlock() qui prend à nouveau deux paramètres: l’un est le numéro de bloc et l’autre est array pour stocker le contenu du bloc. Vous pouvez utiliser la fonction PICC_DumpToSerial() si vous souhaitez voir la totalité de la mémoire 1k avec le bloc écrit dans celle-ci.</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>//read the block back

|
|||
|
|
</code></pre></div></div>
|

|
|
|

<p>Enfin, nous imprimons le contenu du tableau readbackblock en utilisant une boucle for et affichons le contenu sur le moniteur série.</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>//print the block contents

<p>Créons un projet Arduino rapide pour montrer comment un simple module de lecteur RFID RC522 peut être utilisé pour créer un système de contrôle d’accès par serrure de porte RFID . Notre programme analysera l’identifiant unique de chaque étiquette RFID lorsqu’il sera suffisamment proche pour être alimenté par le lecteur RC522. Si l’UID de la balise correspond à une valeur prédéfinie (balise principale) stockée dans la mémoire Arduino, l’accès sera accordé. Et si nous analysons toute balise inconnue, l’accès sera refusé.<br />
