Y'all: Since I design pagers for a living, I thought I might comment on encryption in pagers. I've been thinking about encryption in pagers for several years now. RC4 was suggested, and it is probably a good choice for the low end microcontrollers used in pagers. The problem with encryption in pagers is not algorithms, hardware, software or even technology. The problem is getting awareness that there is a problem transmitting pages in the clear. Most people have no clue and I've seen not one request from a customer (meaning large paging companies) for encrypted pagers. A few more well-publisized hacks will help, though. Code space is at a premium in a pager, so widespread awareness of the inherent insecurity of paging protocols will be necessary to get encryption into the products. So, here's a project for any hacker with time on their hands. Input the audio signal from a garden variety scanner into your sound card (just about any variety will do) and decode the signal. It's just 4 level FM. I'd do it myself, but I value my job. :-) Or, if you're lazy and have money, buy yourself a SignalPro and decode two channels simulaneously. Then, scan paging systems in strategic locations and post the juicy tidbits to the 'net. TTFN, Gold Dot golddot@nym.alias.net "Gold is money, and nothing else is." -- some dead guy
