Re: [TheList] Encription installation commencesthey are saying that they will have rolled out to all the channels by 2014, what channels do they class as low priority? what would the South Canterbury channel be classed as?

The police will be the same as the GSM & CDMA phones, not something to listen to with the new technology.
BUT
5 years is a long time for technology!  Some cleaver bugger will get it to decode.....
But then it will be a matter of "National security" and you'll be taken to court as a terrorist for listening

Cheers
Mike

All encryption is breakable, however the encryption that will be in use on the new network will be safe for a number of years... 

However obtaining radio key then keeping up with the re keying would on paper work, you would need some very clever bunny to write some rather complex software and there just isn't the interest world wide to put the required effort into it. Then you also face the fact that it would be illegal to decrypt it even if you could. Also I don't think Police I&T will be given out keys in fortune cookies to begin with. Even if you were to lay your hands on a radio, you will not be able to read the key from it.

So I guess it is back to whatever it was we did before scanning :-(

Even then, no.

As Neill posted a few days ago, it requires 10,000ish years was it Neill? with the current available computing power to crack the key. But the key changes frequently so it will be quite out of date after 10,000 years anyway J

This system has been in use around the world for years, no one has cracked the encryption, and it is widely believed that no-one will anytime soon.

But if anyone wants to fire up the dusty old 386 in their garage and have a go, by all means be my guest J

Do you really think it will be that simple?

(Answer = no)

Well thinking outside the circle

Wouldn't it be easier to just get the same speced radio and secretly clone one of the others and disable the kill feature?

another thing, if its a case of having the key - have some way to recognise the data transmitted to change the keys/encryption and set up some system to only listen for that change and record/decode it?

Cos surely at some stage someone will have a radio turned off or battery go flat when the new key is transmitted so will have to listen out for it unencrypted or is this some multi-layered system that can transmit with multiple different sets of encryption at the same time?

Food for thought?
