Nextiva is a cloud based VoIP phone system, hosting lots of small and medium sized businesses nationwide. the provides UNLIMITED business calling for only $19.95 a month!! Click here for the detail about this promotion!!

I found straight this article in heise on-line Ticker. Already is frightening!!!

http://www.heise.de/newsticker/meldu...kt-893693.html
Yes, particularly frightening is the recommendation Quotation:
Be generally recommended it to keep radio telephone calls short and To avoid silence.

In that Picture stood somewhat from mobile phones?
Yes, also one can probably crack GSM in the meantime. With heise one finds in addition the following article: http://www.heise.de/newsticker/meldu...ht-892911.html

Quotation:
Now it is further a step, so that telephoning with DECT devices themselves with correct implementation of the coding functions accompanying with the standard by a manufacturer as uncertain to regard is.
Then it is time in the forum thereby to finally stop here the people DECT to recommend.
Hello,

what is the alternative?
The again breaking out Paranoia is IMHO really very unreally. Beginning of last yearly we had this topic already.
To best all transfer cord-bound telephones or write letters
My SX353 has still another “bone”. I will continue to telephone nevertheless over the mobile parts.

For the future is improvement to foresee (“DECT II”): http://www.golem.de/0912/72120.html.
Paranoia! Perfect expression for it.

The DECT standard including coding exists for almost twenty years. Now someone made itself the trouble finite to crack the coding. That shows nevertheless already, how the affair is “interesting”.

But become surely on now everyone Street corner criminal subjects - or perhaps even the protection of the constitution! - stand and harmless citizens with their telephone calls belauschen. Exkrement!

To all, which believe in conspiracy theories: Each kind of the coding, which was invented by people brain, can be cracked also by people brain.

Greeting,

(Name coded. Might be cracked however soon.)

With DECT you send it anyhow without cover

DECT was never coded because as we for over one year knows, that did not implement most manufacturer DSC at all, pure Werbegag.

And does not hear itself so on as if the “trouble” had to break:
Quotation:
A cause for it is according to that Kryptofor Karsten Nohl, which followed meanwhile deDECTed that engineers would have already geschludert with the installation of the coding code and would have gone back in favor of a faster Kryptierung first intended additional procedure securities clearly in the form of no-load operation rounds.
Naturally there are for it 2 reasons instead of conspiracy theories and Nohl's speculation (if Heise it interpreted correct):
1. Personnel expenditure for firmware developers with Kryptoverstndnis.
2. Production and development costs
3. Facilitated hearing possibilities for security authorities

Engineers nix debt.

Nonsense. Gigaset e.g. a list published, from which it follows that all newer devices code. This list was linked already several times also here in the forum.

If already then WPA2. WPA is already kompromitiert.
And WLAN is clearly more unkomfortabler, because smaller range, worse Akkulaufzeiten, more complicated mechanism, conflict with other radio techniques in the same frequency band.
Hello,

Fritz mini users will thank you for the reference to WLAN. Independently of it it gives both for WPA and for AES (WPA2 coding) first successes.

Here in the forum at the most frequent discussed DECT the basis stations, i.e., nevertheless fulfill Fritz boxes already times the largest requirement of the DECT hackers: to accomplish the possibility, a firmware update.
Quotation:
Quotation of RiVen Contribution indicate Gigaset e.g. a list published, from which it follows that all newer devices code.
… different devices also in the play do not come so long, which switch the coding off. For example: Everyone DECT Repeater - also of Gigaset - sets the coding repealed.

Quotation:

Well, times looks, when WPA2 is perforated. And times looks, for a Gesthne goes to what through the numbers of the “knowing”, if admits becomes.

That tunes naturally, in detail in the forum last year also was discussed here.

It is and remains however simply nonsense maintaining, “DECT was never coded”.

And because those angeflunkert you once, you believe those with second time. Ok one.
I want ne list of an independent organization.

One year is not anything with the cryptanalysis.

Does not tune, if that can according to Specs not be, these disturbances gives it also with DECT and full portable radio cells and with comfort and convenientness against security to argue, then we build nevertheless the security checks at the airports again off…

and if already then RSN, “WPA2” is colloquial language of marketing.
And to a break of a Kryptoverfahrens is to be thought only with plain language, of it is still far WPA/TKIP. A package to transfer to be able does not hand, that is a disturbance no more than at best.

That is useful to you nix without updates of DSC, and that is not in view. DECT II probably requires hardware updates. Much fun with the new purchase.
Hello,

Quotation:

Ok one, if we begin now, Korinthen to k….: RSN is also nothing else, as marketing. The standard behind it is IEEE 802.11i.

Quotation:

The update for DSC in the DECT standard is ratified at the beginning of of 2010, that is visible. And if you are been versed with the marketing terms so well, then you will know, the DECT-II under that marketing-moderately griffigeren term “Cat IQ” are led. Correctly, exactly the technology, which AVMs of products for hp audio, RSS Ticker and audio Streaming use.

And you want to bring that as on the mask-programmed chips of many devices?

Now someone made itself the trouble finite to crack the coding to publish and.
Only because you heard nothing before of it, that does not mean that it did not happen.
Quotation:
Quotation of woprr Contribution indicate Is not correct, that can according to Specs be.
I am sure that much calms the diejenicgen down, which have these disturbances.

Do you belong also to those, which feel safer by these controls?

You is deDECTed thegroup independent enough? Or the magazine “Connect”?
Hello,

@woprr: Read once again your own statement, and that, on which it referred.
In order to require not too much: The firmware went into DECT devices, like the Fritz boxes of updating due to the recommendation of the deDECTed group around the possibility. There the updates of the coding can be in-maintained thus - contrary to the devices without this possibility. Therefore the deDECTed group recommended also specially to fall back to devices with this possibility. And not on devices without this possibility.
Did I express that now understandably enough?
Quotation:

And which is with the hand sets?
You mean that here?
No, or one can in-book Fritz hand sets at Fritz boxes only?
Not only the basis station must know the new procedure.
Hello,

you can drive the hairsplitting arbitrarily for a long time, but that will change nothing in the statement. To DECT to devices also hand sets belong.
Here 'times 'which new in things DECT security: http://www.teltarif.de/dect-sicherhe...ews/38749.html.
Shortly is it e.g. also Repeater give, those the coding not more out-lever.
