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.

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.
