Thanks for your answer,
I think web of trust or tic for tac is not the best solution. Today's
telcos face the thread that anyday P2P networks come up which will
take over most of the customers by offering the same services but
much cheaper. Today's telecommunication infrastructure is adopted to
IMS (IP Multimedia Subsystem) but the future may be P2P networks
where the network owns only some intelligence.
Intelligence has evaporated from the network since the arrival of Internet,
which has reduced the telcos to movers of IP packets losing control over
the payload (much to their chagrin). See e.g.
http://www.isen.com/stupid.html .
Applications on the client will be intelligent enough to start
a phone call, ... .
"Will"? They are already.
These networks can be build up very fast and are cheaper as
to scale up a network infrastructure with increasing load.
The system should be open to be able to integrate new services
in a short time. Skype is already very popular and its customer
numbers still goes up. But Skype is only secure while it isn't
open source, the code and everything else is secret (question
how long until someone hacks it, soon I think). That's the
reason that Skype seems to be secure.
I would trust Amiciphone (http://www.amicima.com/applications/ ) much more
than Skype, at least after the promised release of its source code and
design documents (Matt? :-) )
But an open P2P network, where the architecture, its protocols are
open and available for everyone you still face a lot of security
problems.
Quite the opposite is true: obscurity never buys you security; auditable
design and code may.
I need solutions that are 100% secure, not 80% or 79% as many
trust or reputation systems computed its values. The customer
wants to make the call or use other services with a guaranty of 99,9999%.
Apart from the fact that there is no such thing as 100% security, service
guarantees are about reliability, not security.
