How software defined radios (SDRs) will change security

Locks were considered very secure until the first lock pickers got their hands on it. Phone system were secure until the John Draper discovered some use for the toy whistle in Captain Crunch pack. Infact even the creators of internet didn't think of too much security when it was initially designed.  Its the commoditization of technology which sometimes brings about the worst of all security bugs. And I believe the next round of changes are coming very soon. Until very recently radios were built for a purpose and they rarely did more than what it was supposed to do.   Think of them like the early computers which took a whole room and could only do only type of a job per computer. Todays computer can do all kinds of stuff and unlike the older versions, they don't need to be rewired physically to make them do a new job. Everything is done using software. Wikipedia does a good job at defining what this is. A  software-defined radio  system, or  SDR , is a  radio   communication
