Secure

All RavTrack products use 128-bit AES encryption for their transmissions, making it impossible for other radios, even other Raveon radios to intercept the position reports. The encryption "key phrase" is programmed into each RV-M7 Transponder when the unit is installed. Your position and status information is completely private. AES uses the key phrase to encrypt all position and status transmissions.  The key phrase is programmed into the M7 with the KEYPHRASE command.

And because RavTrack does not use common carriers for their signals, position and status information is not publicly accessible.

Advanced Encryption Standard (AES) is a data encryption technique adopted by the US government.  The standard uses the Rijndael block cipher, and specifies the key and block sizes. The M7 uses a 128-bit block size.  AES has been analyzed extensively and is now used worldwide, as was the case with its predecessor DES.  To date, no government or private party has been able to "crack" and AES 128-bit encrypted message.   This is not true of the older DES system used on other AVL products. 

All radios in your tracking system must have the same KEYPHRASE programmed into them.  The KEYPHRASE is hashed into a unique 128 bit encryption key used by the AES encrption/decryption software within the M7.  A user cannot read out the KEYPHRASE from an M7, so even a stolen or compromised M7 cannot be used to determine the encryption KEYPHRASE.

Besides the AES encryption, there are numerouse technological features in the RavTrack system that make it secure and private.

• UHF radio frequencies, with thousands of radio channels
• Proprietary over-the-air protocol
• Data compression of the position and status messages
• 16-bit ID for each vehicle
• 255 group codes
• And the AES 128 bit cyphering
