AES256 Encryption - DMR Radio

This is a sample of how a DMR signal could be intercepted using software or another DMR radio and what an AES256 ciphered signal would sound like to an eavesdropper. I also show what it would sound like being decoded by another authorized radio with matching key parameters (KID and secret key value). Encryption used: AES256 Software used: DSD+ Radios used: 2- Hytera PD782's, 1- Connect Systems CS700 AES256 is certified to protect voice and data up to the level of Top Secret and there is no known way for someone to break this level of encryption now or in the foreseeable future without resorting to extremes. Other forms of voice security that come with some DMR radios: Basic Privacy: Usually 1-255 , or up to 4 hex characters (65,536 keys) Security: Minimal Basic Encrypt (Hytera)- 40,128,or 256 bit encryption, but the keystream is predictable. Security: Medium Full Encrypt (Hytera)- 40 bit ARC4, AES128, or AES256 ,user selectable, user defined keys. An IV is randomly generated every 360mS and is appended to the secret key which results in the keystream being unpredictable. Security (ARC4): Medium. Security (AES128/ AES256): High to Very High. Extra Hytera security feature: Multi-key Random key When these are selected and the encryption boxes for 64 digit keys are all defined and populated the radio will now change the AES256 key with each PTT of the radio.
