Project WHITE BOX' aim is to allow electronic and cryptographically sane access control to shackspace without the requirement to hand out physical keys.

===== Overview =====
The lock is based on a ELV KeyMatic which is interfaced by a Arduino which in turn is connected to a Fonera WIFI AP via RS232.
Users will be provided with an individual cryptographic key which can be used to unlock or lock the door.


===== v1.1 =====
version [[friedhof:white_box:1.1]] documentation

===== How to use it =====
If you're a member and have been around for a while, you can drop a mail to key@lists.shackspace.de and apply for a key. \\
We've documented the [[process:key:key_request|key request process]] (German) in the wiki as well.

Got your key and need help logging into portal? Here's a couple of tutorials for various platforms:

==== Arduino <> MEGA8 I/O Mapping ====
http://www.arduino.cc/en/Hacking/PinMapping

==== Burning ATMEGA8 fuses ====
To burn the appropiate fuses, use the following command:
  sudo avrdude -p atmega8 -c avrispmkII -P usb -B8 -U lfuse:w:0x9f:m -U hfuse:w:0xc0:m

For the Arduino ATMEGA8-16PU use:
  sudo avrdude -p atmega8 -c avrispmkII -P usb -B8 -U lfuse:w:0xdf:m -U hfuse:w:0xca:m
  sudo avrdude -p atmega8 -c avrispmkII -P usb -B8 -U unlock:w:0x0F:m
  sudo avrdude -p atmega8 -c avrispmkII -P usb -B8 -U flash:w:ATmegaBOOT.hex

==== Fonera ====
The wireless frontend is handled using a slightly hacked series-1 LaFonera access point.

=== RS232 Interface ===
A general description including a [[http://www.dd-wrt.com/wiki/index.php/LaFonera_Hardware_Serial-Cable-Port|pinout diagram of the 10-pin header on the Fonera]] is quite useful to wire it to the Atmega8.  

=== SD-Card Hack ===
We've [[http://www.larsen-b.com/Article/262.html|added a SD-card using the Foneras GPIO port]] and a couple of kernel modules.

===== Software =====
==== Arduino / Atmega8 ====
Software was prototyped using the Arduino platform.
A custom configuration was generated to account for the 12MHz XTAL (otherwise RS232 communications would break).

You can get the code from the [[http://code.google.com/p/shackspaceportal/|shackspaceportal project on Google Code]].

==== Fonera ====
The access point is running [[http://dd-wrt.com/site/index|dd-wrt]].
All data not part of dd-wrt is stored on the SD-Card. A custom init script, also stored on the SD-Card, copies the user database to the appropriate locations inside the live system after boot (ie. /etc/passwd).

==== Data / User Management ====
User data is held in a SQLite3 database and a couple of shell scripts are used to generate, add, manage, and rollout keys to the portal system itself.
