RE: idea

[D B <geggam692000 () yahoo com>]

excuse the top post ...yahoo isnt very friendly

ok ill try to answer this..... 

i am by no means a guru of ip protocols but have
agured this with a few people and decided it will work

chunk of data ..... encrypted ..... sliced into random
chunks ....sent to random  ports in a random order
...add some noise generated to simulate data transfer
that is actually transferred but dropped to /dev/null
( that was added after a discussion )

 with the initial connection being ssl the two clients
agree on ports and the order of real data to be sent
that is then followed with a possibility of someone
sniffing ...IF they break the ssl they then have to
reassemble the data in the proper sequence dismissing
all the random noise

what the port hopping tries to achieve is making it
even more difficult to sniff because one cant just
sniff a certain port.... with a random range u have to
suck in garbage data and this increases the time it
takes to reassemble if it is even possible

that is the base idea ...but i feel that by rolling
the ports we would achieve something similar to the
freq hopping and yes it does create complexity ...but
then isnt all security just a level of complexity
added to something simple ?



if it doesnt work at least i learn to code C++ by
trying to make it

What is the added security value of this ??
Sounds more like "security through complexity" to me.
An IP flow does not have the properties that make FHSS
have and added
value to communications over radio frequencies.
