You need to have a certain amount of security to be able to do secure things. It happens with every new technology that comes along, and it's happening now with the digital signature technology. Obviously, that technology needs to take leaps and bounds, but we are talking about 10 to 15 years. There are so many different things that are involved. There are changes in encryption itself and the mathematics of it, changes so it will work on small devices like Pilots and cell phones.
Security always has to do that.
Ultimately, security enables things to happen, but doesn't do anything itself. There are all sorts of security inventions and innovations. We went from viruses to firewalls to intrusion detection to digital certificates. But like in a lot of other industries, I see a lot of that stuff coming together, as well. Security, digital certificates, biometrics, and smart cards all become as ubiquitous as Ethernet cable, flat-panel monitors, and Pilots.
