And PRC, stop finishing all your posts with "

Everybody goes on about the encryption will never be broken ,you just have to look at "Foxtel" they rolled out something like 35 million dollars to upgrade there system and it only took 16 months to decipher.... Its the old story "Walls are built to be torn down"

I think kilo_lema_317 is right on this one. They said the titanic would never sink yet it did. From memory the iphone which could not be used on any other network in America but the AT&T network has had a teenager manage to work out how to modify the phone to work on other networks. Proving anything is possible.

Nobody said it couldn't be broken. What people have been saying is that the encryption is so detailed that the regular joe-blow virtually couldn't do it with regular pcs.

I also remember reading somewhere that every time a WAPOL radio transmits, it uses a different encryption key, and that even is able to change during the conversation.

You'd need some serious CPU grunt to be able to keep up with it.

However, i'm not going to stand up and say "IT WILL NEVER BE CRACKED" - cause I don't know enough about the technology.

If it happens, I think it will be a small group of people who will crack it. You certainly wont be able to just go out and buy a USB device for your PC that can listen to police radio... well... I don't think so anyway

Im happy to say I dont think it will be cracked for a very very very long time if ever.

If you read about it they have spent some serious cash on some serious encryption.

Sure some select people with the know-how and equipment MIGHT be able to do it, but why would they? A lot of time and effort to listen to a scanner? and I assume it would be a serious offense if/when caught.

That was the example I was also thinking of fly_on_the_wall. I was unsure of the exact details so I posted about the other one. The teenager who haked the iphone has been given a car and job by one of the mobile phone companies over there.

Not the best examples to use gents. Totally different systems and protocols. Also the Foxtel fiasco was done by those with knowledge of the system, and mind you it was a system that did not have 'self checks' in place and thus was able to be compromised. The comms system for VKI does have such things in place.
Along with a rolling encryption key. (As mentioned).

Here in Victoria not even the Motorola Technicians have access to the encryption keys used by VicPol. It is controlled by a small select group with in VicPol.

Obviously there is more to this, but it takes far too long to type it out and can be difficult to explain in text. (and I'm feeling lazy ).

Correct. Even then though with the amount of time it would take to work out a simple 5 second transmission, the key would've changed numerous times and also subsequent transmission missed and thus unable to be deciphered one would think.

Irdeto 1 (The old Foxtel standard) was crackable because hackers were able to get something they had ready access to - a subscription smartcard and a satellite receiver (CAM) - to cough up useful keys and other information that they could analyse and (with the help of insiders) reverse engineer the operation of the card. Plus, being used all over the world there were a lot of Europeans who were very keen to get free TV there so there was a lot of brain power thrown at the problem.

Police digital is different. It uses high grade encryption, and radios loaded with working keys are not obtainable. Also, information about the keys is strictly controlled. (no disgruntled pay-tv insiders!) Since communications is two way any stolen radios can be easily disabled over the air.

Unlike Satellite decoders which are worth a few hundred dollars and are fairly easy to poke around with using a PC, Portable radios that VKI use like the Motorola XTS5000 are thousands of dollars to buy, and many more hundreds for the software, RIB etc for programming - if you can obtain them at all.

Conclusion: Beyond using the resources of intelligence agencies (or perhaps extremely well-heeled organised crime) VKI Digital is not and will not be crackable.

Just forget it.
