Software defined radio technology has been widely adopted for new military and aerospace platforms, government signal intelligence and homeland security systems, and now more extensively in commercial wireless voice and data networks as well. These modern communication systems need to squeeze more channels of traffic into an expensive slice of precious radio spectrum. Military and government requirements for secure communications mandate real-time encryption and decryption schemes that must be increasingly more resistant to interception. In multinational theater of war combat operations, communications systems must selectively ensure certain specific links and reliably deny others.
