 URL routing
 -----------
 
 The hard part about implementing this URL routing in Django is that

-and ``https://tickets.bigorg.com/awesomecon/`` contains only one. The only robust way to do
-this is by having *separate* URL configuration for those two cases. In pretix, we call the
-former our ``maindomain`` config and the latter our ``subdomain`` config. For pretix's core
-modules we do some magic to avoid duplicate configuration, but for a fairly simple plugin with
-only a handful of routes, we recommend just configuring the two URL sets separately.

+The only robust way to do this is by having *separate* URL configuration for those three cases.

+- ``pretix.multidomain.organizer_domain_urlconf``
+- ``pretix.multidomain.event_domain_urlconf``
+
+We provide some helper utilities to work with these to avoid duplicate configuration of the individual URLs.
 The file ``urls.py`` inside your plugin package will be loaded and scanned for URL configuration

+Mifare Ultralight AES
+=====================
+
+We offer an implementation that provides a higher security level than the UID-based approach and uses the `Mifare Ultralight AES`_ chip sold by NXP.
+We believe the security model of this approach is adequate to the situation where this will usually be used and we'll outline known risks below.
+
+If you want to dive deeper into the properties of the Mifare Ultralight AES chip, we recommend reading the `data sheet`_.
+
+Random UIDs
+-----------
+
+Mifare Ultralight AES supports a feature that returns a randomized UID every time a non-authenticated user tries to
+read the UID. This has a strong privacy benefit, since no unauthorized entity can use the NFC chips to track users.
+On the other hand, this reduces interoperability of the system. For example, this prevents you from using the same NFC
+chips for a different purpose where you only need the UID. This will also prevent your guests from reading their UID
+themselves with their phones, which might be useful e.g. in debugging situations.
+
+Since there's no one-size-fits-all choice here, you can enable or disable this feature in the pretix organizer
+settings. If you change it, the change will apply to all newly encoded chips after the change.
+
+Key management
+--------------
+
+For every organizer, the server will generate create a "key set", which consists of a publicly known ID (random 32-bit integer) and two 16-byte keys ("diversification key" and "UID key").
+
+Using our :ref:`Device authentication mechanism <rest-deviceauth>`, an authorized device can submit a locally generated RSA public key to the server.
+This key can no longer changed on the server once it is set, thus protecting against the attack scenario of a leaked device API token.
+
+The server will then include key sets in the response to ``/api/v1/device/info``, encrypted with the device's RSA key.
+This includes all key sets generated for the organizer the device belongs to, as well as all keys of organizers that have granted sufficient access to this organizer.
+
+The device will decrypt the key sets using its RSA key and store the key sets locally.
+
+.. warning:: The device **will** have access to the raw key sets. Therefore, there is a risk of leaked master keys if an
+             authorized device is stolen or abused. Our implementation in pretixPOS attempts to make this very hard on
+             modern, non-rooted Android devices by keeping them encrypted with the RSA key and only storing the RSA key
+             in the hardware-backed keystore of the device. A sufficiently motivated attacker, however, will likely still
+             be able to extract the keys from a stolen device.
+
+Encoding a chip
+---------------
+
+When a new chip is encoded, the following steps will be taken:
+
+- The UID of the chip is retrieved.
+
+- A chip-specific key is generated using the mechanism documented in `AN10922`_ using the "diversification key" from the
+  organizer's key set as the CMAC key and the diversification input concatenated in the from of ``0x01 + UID + APPID + SYSTEMID``
+  with the following values:
+
+  - The UID of the chip as ``UID``
+
+  - ``"eu.pretix"`` (``0x65 0x75 0x2e 0x70 0x72 0x65 0x74 0x69 0x78``) as ``APPID``
+
+  - The ``public_id`` from the organizer's key set as a 4-byte big-endian value as ``SYSTEMID``
+
+- The chip-specific key is written to the chip as the "data protection key" (config pages 0x30 to 0x33)
+
+- The UID key from the organizer's key set is written to the chip as the "UID retrieval key" (config pages 0x34 to 0x37)
+
+- The config page 0x29 is set like this:
+
+  - ``RID_ACT`` (random UID) to ``1`` or ``0`` based on the organizer's configuration
+  - ``SEC_MSG_ACT`` (secure messaging) to ``1``
+  - ``AUTH0`` (first page that needs authentication) to 0x04 (first non-UID page)
+
+- The config page 0x2A is set like this:
+
+  - ``PROT`` to ``0`` (only write access restricted, not read access)
+  - ``AUTHLIM`` to ``256`` (maximum number of wrong authentications before "self-desctruction")
+  - Everything else to its default value (no lock bits are set)
+
+- The ``public_id`` of the key set will be written to page 0x04 as a big-endian value
+
+- The UID of the chip will be registered as a reusable medium on the server.
+
+.. warning:: During encoding, the chip-specific key and the UID key are transmitted in plain text over the air. The
+             security model therefore relies on the encoding of chips being performed in a trusted physical environment
+             to prevent a nearby attacker from sniffing the keys with a strong antenna.
+
+.. note:: If an attacker tries to authenticate with the chip 256 times using the wrong key, the chip will become
+          unusable. A chip may also become unusable if it is detached from the reader in the middle of the encoding
+          process (even though we've tried to implement it in a way that makes this unlikely).
+
+Usage
+-----
+
+When a chip is presented to the NFC reader, the following steps will be taken:
+
+- Command ``GET_VERSION`` is used to determine if it is a Mifare Ultralight AES chip (if not, abort).
+
+- Page 0x04 is read. If it is all zeroes, the chip is considered un-encoded (abort). If it contains a value that
+  corresponds to the ``public_id`` of a known key set, this key set is used for all further operations. If it contains
+  a different value, we consider this chip to belong to a different organizer or not to a pretix system at all (abort).
+
+- An authentication with the chip using the UID key is performed.
+
+- The UID of the chip will be read.
+
+- The chip-specific key will be derived using the mechanism described above in the encoding step.
+
+- An authentication with the chip using the chip-specific key is performed. If this is fully successful, this step
+  proves that the chip knows the same chip-specific key as we do and is therefore an authentic chip encoded by us and
+  we can trust its UID value.
+
+- The UID is transmitted to the server to fetch the correct medium.
+
+During these steps, the keys are never transmitted in plain text and can thus not be sniffed by a nearby attacker
+with a strong antenna.

+UID-based
+=========
+
+With UID-based NFC, only the unique ID (UID) of the NFC chip is used for identification purposes.
+This can be used with virtually all NFC chips that provide compatibility with the NFC reader in use, typically at least all chips that comply with ISO/IEC 14443-3A.
+
+We make only one restriction: The UID may not start with ``08``, since that usually signifies a randomized UID that changes on every read (which would not be very useful).
+
+.. warning:: The UID-based approach provides only a very low level of security. It is easy to clone a chip with the same
+             UID and impersonate someone else.
