This corner of the WWW is devoted to information, documentation and sourc=
e
for the NCash digital cash experiment. Some pointers here are links right
into my source tree, so don't be surprised if you find inconsistencies or
bugs.
NCash is my Master's project at the Link=F6ping Institute of Technology. =
The
idea is to design and implement an bare-bones off-line digital cash syste=
m,
meeting rather high standards for security and privacy. And then try it o=
ut
in the Real World. For simplicity, NCash will be software only, with both
servers and clients running on Unix-like machines.
The cash system being implemented follows the ideas of Stefan Brands'
rather closely, in particular the system described in his 'An efficient
off-line electronic cash system based on the representation problem'.
An excellent introduction to digital cash and related matters are David
Chaum's articles 'Achieving Electronic Privacy' and 'Security Without
Identification: Transaction Systems to Make Big Brother Obsolete', writte=
n
1992 and 1985 respectively.
I'm running a mailing list for discussion of the NCash project. The list =
is
mainly for the persons more or less involved in the project, i.e. me, my
supervisor, other people who have offered help, volunteers who wish to tr=
y
out the system when time comes, and some friends and other interested
people. The main language on the list is Swedish.
To subscribe, send mail to <ncash-request@lysator.liu.se>. The list addre=
ss
is <ncash-request@lysator.liu.se>. There's also an
<http://www.lysator.liu.se/~nisse/NCash/ncash-arkiv>archive.
Ahttp://www.lysator.liu.se/~nisse/NCash/s the design and implementation
proceeds, I try to keep up with documenting NCash. If you dare, look at t=
he
latest snapshot as of August 6th. Also available as
<http://www.lysator.liu.se/~nisse/NCash/NCash.ps>postscript
The <http://www.lysator.liu.se/~nisse/NCash/source.html>source code will
mostly be written in the Pike language, and will probably be released und=
er
the GNU General Public License, but it's not ready yet for some time.
The server will probably run on a <http://www.linux.org>Linux machine tha=
t
the mathematics department has kindly given me access to.
