If the PIN instead of CAN is used as password, an attacker can use it to authenticate on your behalf at a legitimate party. In case of the nPA, EAC (Extended Access Control) is required to access the passport's data. Vervier and Orru presented a closed vulnerability of U2F tokens in combination with WebUSB, whereby the user is tricked into allowing access to his security token via WebUSB by a similar looking phishing website. Compared to giving away your email address and password, you give away a stronger authentication proof of ownership of a physical device. Note: It is a bad idea to hand out your authentication token and its secret to a website. The browser connects to WebSocketServerPACE.py, which verifies the CAN with PACE the responses are shown in the log. ![]() In the section "Remote nPA PACE", enter the card's CAN and click "send".insert smart card that is capable of performing PACE (e.g.Install required python packages manually or using setup.py, see WebSocketServerPACE.py.You need Virtualsmartcard's Python files, either from the install above or manually downloaded, see setup.py. Note: I included vicc-vpcdHost.py, an example vpcd and app. Accessing the card in the virtual reader via PC/SC is relayed through the WebSocket and through the browser the website's log shows the command and response APDUs.clicking "request remote CAPDU" in the section "remote vicc, vpcd, app" connects to WebSocketServerVICC.py, which relayes the card to the virtual smart card reader.start PCSC-Lite or SCardSvr.exe with the vpcd driver) start virtual smart card reader on localhost:35963 (i.e.The Python dependencies can be installed using setup.py or manually, see WebSockerServerVICC.py. Clicking "request remote CAPDU" below the headline "remote WebSocket only" connects to WebSocketServer.py. ![]() Install SimpleWebSocketServer manually or using setup.py, see WebSocketServer.py.clicking the square sends GET CHALLENGE the card's response is translated to the appropriate number of pips on the dice's face.insert smart card that accepts GET CHALLENGE ( 00 84 00 00 00 00 01).click "connect reader" and choose your USB CCID smart card reader.start web server ( python3 HttpServer.py).SSL/TLS encryption is left off for debugging. You need to enable SSL/TLS encryption, if you want to host the server on a different machine. Once your WebUSB device is available for the browser, in user space, you can follow the instructions to get the demos up and running. Vendor Id and Product Id of your CCID can be identified using lsusb command. A generic rule for (specific) WebUSB devices could be added to the udev project. See the following example rule created in /etc/udev/rules.d/les and adding your user to the plugdev group in etc/group. This can be done by creating a custom udev rule. For Linux, the user's browser needs write access to the usb device.For Windows Zadig is recommended to load the generic WinUSB driver for your CCID.Or opt for a browser extension (not plugin) approach to access respective native components. To use non-WebUSB readers in production, it may be a better idea to provide a proxy WebUSB driver, which forwards messages to the hardware and does necessary security (origin) checks. Otherwise, for debugging, you can use an old Chromium Snapshot e.g. If they use a different interface class, not one of, they can still be made available using instructions below. 0) those readers are blocked for security reasons by their respective USB interface class (0x0B). As of April 2018 (Chromium Build > 546309, version. Making a traditional, non-WebUSB CCID available to WebUSB requires operating system specific actions. In doubt, try to make it accessible using the instructions for non-WebUSB CCIDs below. If your CCID is WebUSB compatible, you should be able to use it out of the box. |Smart||USB CCID| ifd.js WebSocketServerPACE.py +-+ +-+ | | | | on server in virtual reader) +-Chromium (based) browser-+ +-> WebSocketServer.py
