Thank you for quick reply, Gunter!

Very interesting article Gunther and shows the very sad state of affairs.

That's exactly what I wanted to express saying "That's good link ! "

Reading the posts in this topic, it appears that the security item is voice rather than just data and if the need for communication is normal multi-node then a specialised VPN would be a good starter. Now to secure it would need to again be specialised in that various encryption schemes are available between any 2 nodes but in addition to that the military of most advanced countries have scrambling technology for voice communications. Sky News long ago had a variable base encryption method that varied over time so that even if someone cracked it at some instance, it failed quickly as the base changed.

Now with a multi-tiered approach like this you could have the KGB, NSA, Mossad or whoever else wanted to listen wired into the server just down the road which IS probably the case but if the system is both complex enough and variable in its base, you should be able to keep them guessing for a very long time. The greatest weakness of any system like this or in fact other systems is an insider leaking the system to the enemy but that is a human challenge, not a security technology problem.

yes, The Human Factor, copyright by Graham Greene and Otto Preminger. A very important aspect.

With the Ivy Bridge processors (successor of Sandy Bridge), Intel introduced the new RDRAND instruction. So far, so good or bad. Rumors via the net say that this new instruction is backdoored (better kleptographiced) by the NSA. Interesting. Where is the end?

Thief or not, here is an interesting post by Ted Ts'o from the MIT.

Yes, very interesting. And it will be interesting to see how Intel responds to the backdoor claim, the lack of access to the entropy source, etc, and if someone manages to prove the claim.
Well Microsoft, here’s another nice mess you’ve gotten us into.

you will know you hit the nail on the head if the response is prepared by the OSI
their MO is to make you look like an idiot and "expose" you as a conspiracy theorist
they won't apologize or act disgusted

Don't miss new Core-123 with SSE-456!
It features:
Automatical updates of the microcode downloading directly from vendor (mobile internet modem is integrated into CPU, the updates may not be turned off :greensml:)
Execution of encrypted code in the local memory of CPU - may not be examined or debugged (and may contain any stuff we (not you) want to have run on your PC)
The world-wide service of hunting for scam, malware and other unwanded apps (some day booting your computer, instead of a boot-strap and OS loading you may see nice message on a display: "We did not like the expression of your face, so you did not pass the CPU face control. Don't try to disable the camera on your PC, the CPU is already locked, as well as all data of your HDD is removed." :greensml:)

The CPU is only $999.95, the M/B build on a chipset "The hand of trust on your shoulder"(ТМ) is another some bucks.


:greensml: Just joke

Surely Intel learned from the PSN fiasco?
