Subject: FCC Packet Message Forwarding
In response to Jay's (KA9OKT) (jay@medicine.dmed.iupui.edu) proposal for user
authentication -
>When this ham wants to send any message through my BBS, he would be required
>to place an authentification string at the bottom of the message. This string
>would be calculated based on the person's call sign, his private key, and
>the text of the message.
Donald D. Woelz says -
>Well, the only problem I see is that any station that can monitor
>the packet frequency can obtain the authentication string and then
>forge messages with that callsign.
My feeling is that because with Jay's proposal the text of the message
would be one of the items used to generate the authenticator, that
authenticator would only hold for that particular message, and so
should help overcome the problem of replay of authenticator.
A good system for 'client' authentication already exists in the form of
Kerberos from MIT. Perhaps we should see if a variant of Kerberos is
appropriate for PBBS user authentication. After all, why re-invent the wheel.

Subject: Macintosh Loader for TI DSP Starter Kit available
To: ham-digital@ucsd.edu
I have uploaded a loader program for the TI DSK on
info-mac at sumex-aim.stanford.edu.
DSK_Loader 1.0
DSK_Loader is the Macintosh equivalent of the DOS program DSKL. With this
program you can communicate with the DSK (DSP Starter Kit) from Texas
Instruments. This program bootloads a simple communications kernel and then
loads other software using this kernel.
Other options are:
* Fill DSK memory with a certain value.
* Dump DSK memory into a textwindow, for further processing.
* Execute programs on the DSK.
* Graph output from the DSK.
* Act as a dumb terminal to the DSK.
The DSK and thus DSK_Loader is most interesting for people who want to
experiment with Digital Signal Processing at low costs.
For HAM-Radio operators it is a very interesting piece of equipment, Some
applications, like the KC7WW port of the W9GR filters are included.

I will also make this program available in the ham radio section on
oak.oakland.edu.
I invite all readers to submit non-commercial ham related programs to
the oakland site.
The upload directory is: /pub/hamradio/incoming
Thanks, and 73,
Scott

Subject: NTS...
Packet radio is currently a world wide phenomonen.
NTS is a USA only abberation. In most parts of the world third
party traffic is expressly forbidden, except in case of emergency.
PLEASE do not make proposals about changes to the PBBS system for
NTS without regard to the impact on the rest of the world.
