[Cryptofon-project] [Cryptofon] - Pre-release Specification draft

[Netzblockierer <Net...@pr...>]

Hi everyone,

I just finished the basic specifications as a VERY FIRST DRAFT, and
would like to hear from you what you think about it...

Until now, I did not figured out about the modem... I guess to keep it
universal first, but maybe an improved version of the CCC Modem
[http://www.offiziere.ch/trust-us/habi1/097_datenklo.html - german] may
work pretty well... As you can read in the specs - it needs 2400 bit/s
uplink and 2400 bit/s downlink....

As those acoustic modems seems pretty easy due to their use of FSK
modulation [ https://en.wikipedia.org/wiki/Frequency-shift_keying ] -
they keep the entire Cryptofon technology neutral...

For now, we may consider looking after some kind of FTDMA and STDMA
chips as well as crypto processors, supporting up to 8192 bits key
lenght... Besides that the programming needs to be done...

I'm looking forward for your feeedback,

Greetings,
