Does anyone know how to crack rf encryption? I know its possible, see I was thinking of starting by intercepting an encrypted signal with an ICOM IC-PCR1500-30 EXP Unblock PC Receiver scanner and then running it through some sort of decryption engine. Does anyone know how to do this? It depends on the type of signal you're trying to decypher. Dr Dre 2001 The Chronic Zippy there.

Send a message which is digitized and encrypted (locked) and can only be decrypted (unlocked) and received by those radio. The P25 Common Air Interface (CAI) supports use of any of the four types of encryption algorithms. APCO Project 25 (P25) Standard Requires AES Encryption for Interoperability Purposes.

There are some references to breaking encryption on a P25 system that I have come across. I've managed to decode police TETRA communications but the speech is scrambled so about all you can tell is the gender of the radio operator. More likely to be DMR or APCO P25 in the States.

Some systems use analog encryption which is shifting tones/harmonics of the original signal or pilot tones in psudo-random methods to obscure the original signal. Some use digital which digitizes the analog signal and uses cyphers on the bits to secure the transmission. First thing you should do is find out as much about the transmitting system and see if there are any docs available that describe what form of encryption they are using.

At least that would give you a starting point to figure out decryption. The signal is AES encrypted on apco-25 digital using Motorola equipment. When listening in on it, it sounds just like nothing is there. Sort of like the static you get when you turn the squelch all the way down on a frequency that nothing is transmitted on. The only way one can know someone is transmitting on the frequency is because the scanner keeps locking on the channel and the 'static' goes on and off in the same intervals of normal communications.

Also the dispatch or base operator is not encrypted some of the time. The ecryption used is DES, Digital Encryption Standard, and more recent AES, this type of scrambling is found on certain type of Motorola equipment. Digital Encryption sounds like a bunch of tones and beeps and is quiet nerve racking. AES sounds like static. Both use a preset code or 'key' that can be anything of about 10,000 different combinations. These combinations are changed periodically. Maybe it could be cracked be using a computer program that could sample the combinations super fast.
