My company developed a product that uses GSM/CSD mode to send voice encrypded using 256 bits Rijndael. I don't know if in Europe my product works. I have a XDA working fine here in Brazil. I will apreciate if my software could be tested using the XDA and XDA-II (we don't tested-it with the XDA-II), because we don't have how to test-it in Europe.
My site is http://www.raseac.com.br , and in the site we have a working demo with 128 bits security and one minute of conversation per call. We have also a manual in PDF format (in english).
I will apreciate some help from Europe.

I think you might consider looking also for European based solution, similar but using specifically MDA / XDA for encrypted comm
http://www.cryptophone.de/html/products_en.html
BTW when you consider introducing fully fledged and operational version for wm2003 ??
regards, monika
Thank you for your interest in our product.
We will test our product with the wm2003 in the next month, but we can't have a date limit to finish the compatibility test yet. There are a lot of hardware available to run our product. I will remember you that we are selling software (not hardware like cryptophone), and to sell our product we need to make compatibility tests in a lot of hardware . Our idea in this case is, if you have a hardware available (like the XDA), you only need to buy a software (and not the hardware that you already have). You investment in this case will be US$149,99 for the 128 bits version (US$ 249,99 for the 256 bits) in order to have a solid voice encryption product. Our product uses a TAPI modem linked with a PocketPc 2002 handheld by cable, bluetooth or a compactflash connection, and uses fixed, cellular and satelite lines. We tested the Raseac Secure Phone it in a lot of hardware (we have our product in our lab running in a XDA). We don't know about the CSD (Circuit Switched Data) quality in GSM networks outside Brazil (we are asking the readers to test-it and send us their comments). The bonus in this case is the use of a solid 128 bits voice encryption software free for one minute of conversation per call, with no limits in the number of calls (our freeware version).
Thank you.

Sorry for the mistake in the price: The correct values are US$149.99 for the 128 bits version and US$249.99 for the 256 bits version.
Thank You.

How do we know if the software is actually carrying out the encryption, and that the voice is actually being encrypted is there something obvious that will let me know this.
The encryption is the easier part to be done in this system, if you see the user's manual, the most part of the system is the user interface and its architecture (our strongest point is our system design).
If you made a system that sends and receives voice without encryption, in our case you have 90% of the work done (error correction, codec optimization, software optimization). Think about reading the voice signal, compressing this signal using a voice codec, building the telephony interface, optimizing the code (our system is full-duplex), working a lot to optimize the code and let it running with quality), and until now i am not talking about encryption.
You can see in the google a lot of stuff about encryption (random number generators, hash functions, encryption functions), the encryption library available is huge.
After that work done to send and receive voice in a 4800 bauds line, you will see that 95% of the job is done. But i will remember that: To this system be a security system, all this design must be done before build the system. It is very dificult to transform a voice transmition system in a good security system(almost impossible) if you don't thing in security before building the system.
Now a little bit about encryption.
Our design is completely different from vast majority of the voice systems designs, we use block mode encryption and CBC mode encryption. The vast majority of the systems designs uses streaming mode. We generate an external random file in order to use the random numbers by the system. You can analyse this random file, it passes in the Diehard test (you can download the Diehard test and submit our generated file).
Each contact used by the system have its own master key, and you can edit this contact master key.
If you change one bit of this contact master key in your handheld, you will not be able to do the voice connection with the other handheld.
After reading our user manual, available in our site, you will see that this system was carefully built having security in mind, because you will see that you will have a 50 pages manual with a lot of information about security, and I invite you to read this manual (again, you will see a lot about our system design in this manual).
The Raseac Secure Phone security system spec will be published in february, and after that we will ask for an independent organization to analize our source code and publish the results (We think that the common user doesn't have the competence to analyse the source code). Our source code will not be available to the public only because commercial reasons, we sell software for commercial hardware available in the market (unlike our competition that sells proprietary hardware and have the copy protection inside their proprietary hardware), we have our system copy protection inside our code and we want to protect our intelectual property.
A little bit more about proprietary hardware systems: If you sell a hardware system and publish only part of the system (you can't garantee that the operational system was not changed in a dangerous way to compromise the security), the source published doesn't garantee the security at all.
Thank you.

A big hooray
Shame about choice of phone's and that none have wifi.
I have been pissed with T-mobile bot allowing many services on web n walk.
3 embracing skype and opening up to data tarrifs.
Thank you. Lets hope you start a trend/price war.
Although I will wait until I see the charges.
Did I read on these same pages yesterday the o2 chairman predicting 3 and virgin would not last. Show them the way to go.
Just need more broadband routers with better igmp support for alll the video streaming,IPTV etc that is gonna be coming.
This all sounds good, and it is very tempting to go with 3, especially with x-series services coming up. Free unlimited international calls (Only to certain countries) aswell, for £15!!
However what I would like to know is, do you have to use 3's phone to get free access to internet, skype, messenger etc. i.e. does 3 load on their own version of these software to access these services? By reading articles, it seems they do, for example, you can only use Yahoo Go and Google to browse or search the internet. Or could you use a PDA phone (say HTC Trinity) with your 3 sim, and open PIE and surf the net for free, use skype or Live Messenger for free?
Ideally, I would like to get my own PDA phone (maybe trinity) to take advantage of these services, but I have a gut feeling it's not as simple as that. It's a shame that there's only two phones they currently offer that support HSDPA, Nokia N73 and SE W950i. I rather have the Trinity
A friend who works for vodafone said that they will be following up with some new data tariffs around January time - fingers crossed, dual sim with web-n-walk doesn't quite cut the mustard for me!
agree with the two posts above, web n walk is great however the t-mobile call reception is terrible in my area. The 3 hansets avaliable are not to my liking. My O2 contract expires in January, at that point i hope i have a decent choice of data plans......
Hello all
I've been reading this forum for some months now and i like the windows'es and informations i've found here on my Hermes device
But now i have some questions on using the often integrated tool field test.
I've found out that with the IMSI-catcher (german wikipedia as one of the sources), that are more and more often used semi-legal by the police(here in europe there are a lot of 'GA-90' devices sold to the police and other institutions), it is possible to listen to phone calls(man in the middle attack), by just 'emulating' the strongest phone-cell in the area, to which the device connects instead of connecting to the provider's cell.
I also read that it would be possible to find out if there was an imsi-catcher device active in the area near you or not. The only thing needed is a special monitor software (field test?) that observes the MNC(Mobile Network Codes) behavior(appearently you need 2 handy's from the same provider with the monitoring software running).
But they didn't explain exactly on which behavior you should pay attention.
Since I could use 2 windows mobile devices to test this out, I am searching for more detailled information on this subject, and the first place that came in my mind was xda-developers
I allready did search this forum for the subject imsi catcher, and the only thing I've found is this.
google result
so one person who tries to change hies imei number, and another one who doesn't seem to know exactly what an imsi catcher can do.
Is here anyone who knows more?
I know that where I live, there are pple who make abuse with IMSI-catchers(catching calls without the permission from a judge or similar, or even one time someone listening to his girlfriends phone calls to see if she's cheating(and she did and that was the reason he left her))And yes this one was a young policeman who told that to his friends and even was proud of it.
I also dislike the fact that the handy, instead of the encrypted one with the provider's cell, has an non encrypted connection to the imsi catcher(if not there would be no possibility for a listening man in the middle attack).
I also read about the cellphones from http://www.cryptophone.de/
Appearently they do allways have encrypted conversations even through an Imsi-catcher. But if that would be true, the other side will need the same handy to decrypt it again. Because it has to encrypt, the allready encrypted data traffic with the provider's cell, if not it can't allow any protection against IMSI -Catcher devices. I also ask myself if, depending on where u want to use it, the 2nd encryption could produce a to huge phone traffic that could result p.ex. in a robot voice...
Anyone who could light me up?
Or is there any software able of reencrypting the encrypted transfer on windows mobile devices?technically it should be possible(2nd phone dialer installed so you choose the normal one for normal calls and 2nd one for calls with pple who also have this software installed on their phones)perhaps not with an 256 bit encryption but perhaps with a 128 or 64 bit encryption...
BTW, if there would be anyone able to programm such a hot piece of software for windows mobile devices I wouldn't have any problem to donate him with paypal, and i suppose other pple would do the sameAnd no I don't wanna replace that by Voip or skype via HTC...
Thanks in advance
Patrick
So no one who knows more about this?
I would be very happy if i could at least test if they're really used that often as they say they are(where i live).
And since i could try it in different major 'cities' over here, i suppose catching a imsi catcher soon or later
I'm quite curios if all the pple, telling that there is a lot of abuse with these machines, are right, or if that's all nonsens...
It would be nice if a warning icon could be integrated into Windows Mobile or the dialer to indicate that a call is not being encrypted. Read the Wikipedia entry for IMSI-catcher for more info. I'm guessing CDMA is largely unaffected since the hole seems to rely on the UMTS spec's backward-compatibility with GSM.
I'd also like to note that Skype is the way to go for true endpoint to endpoint call encryption. You know, if you're a gangster or something and need to brush off the popos. It would be interesting to investigate whether the WM6 integrated VOIP stack requires authentication/encryption.
Anyone here using Seven on their Tilt with the new ATT Rom?
I've been using it for about 2 weeks just fine with no problems whats so ever. Now since flashing my ROM I started having issues.
The two main ones are that messages are not getting marked as read back on the server side and that composed messages are not being sent.
Anyone else here seeing this?
I am running the official ATT WM6.1 ROM.
Thanks
David

I am using Seven on my TyNT II now and it's working fine.
However, I don't know if you all know that when you setup an email account to SEVEN, your phone automatically sends an sms to an England number +447624802625, which will charge you an international sms. This will happen when you add one and every email account. Here is the confirmation from SEVEN:
abackholm - SEVEN's Site Admin said:
First of all, thanks for everyone supporting SEVEN in participating the beta program. Your efforts have continued to help our software reach higher quality and become more reliable. Sincerely, being a non-commercial offering that does not earn SEVEN a dime, we sometimes put you in a difficult spot: the setup is not necessarily optimized for the end user, but rather to maximize feedback and exposure SEVEN gets for various features and setup configurations.
In this case, we want to test the phone number validation using SMS.
(1) In production deployments we need user's phone number (instead of IMSI) to be able to send SMS triggers that wake up the client so that there is no need for always-on data connection - to conserve bandwidth and battery.
(2) In production deployments the SMS would be zero-rated, but that's unfortunately not an option in the beta program as operators are not participating with beta testing in their mind. In such deployments, there is no need for multiple SMS-to-HTTP gateway numbers, and thus our setup only supports using one at a time. As the beta program is global in nature, majority of users will always have to use an international number.
I apologize for inconvenience this causes. I realize that those who need to reinstall the client very frequently are especially vulnerable. However, I'd like to remind that participation in the beta program is entirely voluntary.

And luckily some solution has been found:
Hi guys, the problem is over for me as I found a trick for this. There are two ways:
1. I just install and run SEVEN with an OUT-OF-MONEY SIM so that it could not send any international sms. I don't know if you have this in your country or not but here we have 2 different accounts for one SIM, the main account and the promotion account. With the promotion account we can use most of the sms, 3g, gprs, phone services but not international sms/calls and value-added services (like buying ringtones, games etc), and the main account covers those things. So I've tried a SIM without money in the main account and everything goes great though it could not send an international sms. When I put my other SIM in, it does not request me to activate Smile
2. I've tried to install and run SEVEN without a SIM, and turn the wifi on when I add emails. SEVEN requested me to input my phone number and I did it. Then when everything is done I just insert my SIM in, and everything worked fine, no more international sms.
Cheers!!!

and
I can add that I have just disabled the phone connnection and connected via wifi when adding an account. This also works.

Greetings,
I have been on the look out for a tablet for quite some time now.
Some background information:
I am currently a University student, and I enjoy power hungry video games like Diablo3 (if you think d3 isn't power hungry, ok. It isn't the point of the thread.)
I owe a gaming pc - Nvidia 660Ti, and a Tablet / Ultrabook Hybrid - Asus Taichi 31.
I live in Malta. (A&T and T-Mobiles are not available, I have yet to contact them wheter they are willing to offer their services from abroad regarding a data plan) (to my knowledge acquired from these forums, there is currently no possible way to integrate voice calling / smsing with the mini sim. The mini sim is only used for data transfer correct?)
I understand barely nothing about android, roms and kernals, I am studying for a pharmacist. What little I know is mostly about desktops from my interest and sources are typically the internet and some local technicians I enjoy chatting with. (if any1 can point me to a good beginner guide, that would be great)
I am currently looking for something that is able to:
replace my phone - just calls and sms. My lack of education on android devices and a very narrow google search lead me to believe there are apps with this ability if you are always connected to an internet connection? which wouldnt be a problem with the LTE/4G?
good alternative for an mp3 player - main issue: buttery life - size doesn't matter because I use bluetooth headphones
use XBMC hub - i think this tablet can easily handle it
take decent quality photos
stream games from long distances (when I am at university example, from my home) - is the only limiting factor the speed of the internet connection? Is it possible to connect the internet via a cable? (ethernet to mini usb converter?)
My two main priorities are calling/texting and battery life.
I am yet to find a store who has this tablet on display so I can have a feel of the tablet, I do not know if 8'' is ridiculously large to carry around. And I think it also falls within personal preference.
What would you, if in my shoes, get? Should I look for a phablet? I personally find smart phones have a small screen, and the only use I have out of a phone is to text and call, so I would like to have the good out of both ends.
Thank you.

It can meet your needs. You can use Google Voice # and hangouts to make/receive calls. It is a beast at gaming and the nvidia game stream is great, however its huge. In my opinion WAY to big to be used as an everyday phone, and would only allow speak phone calls or through a blue tooth. The call quality is good though.
If you want a tablet I recommend it. However if you want a phone I suggest using a phone.
I would get the tablet then get a Moto G or a Moto E for free and use it as your phone.

GV is google voice? Yes I live in Malta, and thank you I didn't know that.
Is there any other way possible to have voice call / texting possibilities on this tablet?
