Indian UAV's are seriously Flawed.........

The Indian army uses over 100 UAV drones (Unmanned Aeriel Vehicals) for gathering enemy locations & SIGINT purposes, most of the UAV's are the Israeily HERON & SEARCHER UAV'S which were purchased by India from I.A.I(Israeily Aircraft Industries) in 2006.
These UAV's are extensively used to carry out image mapping & gathering intelligence data by the army, But these UAV's have a seriously flaw, that whatever data that is sent by these UAV's to the base station is unencrypted data & can be easily tapped by the enemy.
Though the army has recognized the flaw & is working on it, it may still take a very long time to be rectified as the UAV's would again have to be sent to I.A.I Israel.
Recently it was reported that a group of Iraqi insurgents were able to crack the encryption used by the Predator UAV's used by the US in iraq using a simple software called SKYGRABBER which is easily available on the WEB.The question arises that when encryption of US Predator drones can be cracked easily, then its highly possible that the same situation can be repeated with the UAV's used by the Indian Army!
