<h2><a name="news">News</a></h2>
<div class="news-date">Sat Dec 6 2003: </div>
<p class="news-text"><a href="@PACKAGE_URL@aeswepd-0.4.tar.gz">Version 0.4</a> released, changed default rekeying time to 24h, updated wireless extension header, small fixes.</p>
<div class="news-date">Fri Oct 17 2003: </div>
<p class="news-text"><a href="@PACKAGE_URL@aeswepd-0.3b.tar.gz">Version 0.3b</a> released, small bugfixes.</p>
<div class="news-date">Fri Oct 17 2003: </div>
<p class="news-text"><a href="@PACKAGE_URL@aeswepd-0.3.tar.gz">Version 0.3</a> released, split from <tt><a href="http://0pointer.de/lennart/projects/waproamd/">waproamd</a></tt>, added documentation, manpage, some bug fixes.</p>
<h2><a name="overview">Overview</a></h2>
<p><tt>aeswepd</tt> is UNIX daemon for changing WEP keys of WLAN devices in
constant intervals. The WEP keys are calculated by encrypting the
current UNIX time using the AES cypher with a given constant
key. <tt>aeswepd</tt> strengthens the security of the weak hardware based, standards
compliant WEP technology.</p>
<p><tt>aeswepd</tt> may use up to three hardware WEP keys: the first is
set to the current, the second to the previous and the third to
the next key. This is useful when working with not completely
synchronized RTCs. If only a single hardware WEP key is used, you
have to synchronize your RTCs so that no connectivity interrupts
may occur.</p>
<p><tt>aeswepd</tt> has several advantages over other solutions to
improve WEP: it is easy to use, doesn't involve computing intensive
algorithms, doesn't increase traffic latency. On the other hand it has
several disadvantages as well: it requires an installation of
<tt>aeswepd</tt> on all network members, it is not standardized,
currently only APs which run a flavour of Linux may be used with
it.</p>
<h2><a name="status">Status</a></h2>
<p>Version @PACKAGE_VERSION@ is more or less stable. It features only a single WEP
key driver for local NICs supporting the Linux wireless extensions
v15. Support for changing WEP keys of remote APs via HTTP is planned
for the next version.</p>
<h2><a name="documentation">Documentation</a></h2>
<p>Have a look on the man page <a href="@PACKAGE_URL@aeswepd.8.xml"><tt>aeswepd(8)</tt></a>. (An XSLT capable browser is required)</p>
<p><tt>aeswepd</tt> has no configuration file. It is intended to be run with correct command line arguments from <tt>ifup</tt>/<tt>ifdown</tt> or <tt><a href="http://0pointer.de/lennart/projects/waproamd/">waproamd</a></tt>.</p>
<h2><a name="requirements">Requirements</a></h2>
<p>A newer Linux Kernel with a compatible device driver and WLAN NIC
(Wireless extensions v15 or newer). Most modern cards and drivers are
compatible, like mines which work with the <a href="http://www.hostap.org/"><tt>hostap</tt></a> driver, version 0.0.3 and above.</p>
<p><tt>aeswepd</tt> was developed and tested on Debian GNU/Linux
"testing" from October 2003, it should work on most other Linux
distributions since it uses GNU autoconf for
source code configuration.</p>
<p>The machines used for development are a Medion 9580-F laptop with a
TEAC and a ZONET PCMCIA WLAN NIC, and an 1 GHz Celeron PC with a noname PCI
WLAN NIC. All three cards feature a PRISM2 chipset. <tt>hostap 0.0.4</tt> was used as driver.</p>
<p><tt>aeswepd</tt> needs <a href="http://0pointer.de/lennart/projects/libdaemon/"><tt>libdaemon</tt></a> and <a href="http://mcrypt.sourceforge.net/"><tt>libmcrypt 4</tt></a>.</p>
<h2><a name="installation">Installation</a></h2>
<p>As this package is made with the GNU autotools you should run
<tt>./configure</tt> inside the distribution directory for configuring
the source tree. After that you should run <tt>make</tt> for
compilation and <tt>make install</tt> (as root) for installation of
<tt>aeswepd</tt>.</p>
<h2><a name="acks">Acknowledgements</a></h2>
<p>None so far</p>
<h2><a name="download">Download</a></h2>
