A significant part in the process of developing wireless networks is ensuring that the data on wireless devices is secure. What do you see as the biggest threats to that security?
I'm not sure what you're driving at here. Maybe you refer to the security of the data while stored on the wireless device, as opposed to "in transit". Of course this is a problem that applies equally to both wireless and wired devices. I suppose mobile devices are more vulnerable because they are more easily stolen or lost. There is clearly an argument that says information should be encrypted at source and decrypted only when used. In other words it would remain encrypted while stored on the device and only be decoded when the application needed to access it. In the extreme, the decryption would occur inside the microprocessor so that it could never be accessed out of context. I believe there are some ideas going forward in this area. In such a case it might be argued that in such a case security is no longer needed for the wireless links but, in practice, there are attacks other than on data content which need to be defended. I think you'll still need separate wireless security for the foreseeable future.
Warchalking, Wardriving, Warspamming - these are just some of the terms we see frequently in the news. Do you see these actions as a real problem or is it just the media making things bigger than they are?
Well, far be it from me to suggest that the media exaggerate things! These attacks are real and go on everyday. But I have to say I've never seen anyone walking round my district with a laptop and a piece of chalk. For me, the novelty of war driving could wear off pretty quick. These days there are so many Wi-Fi networks out there, and so many of them are unprotected, you probably don't need to drive anywhere. Chances are your neighbors are already open for business! This is the problem we need to address.
What are your predictions for the future when it comes to wireless security? There has been a lot of talk about the insecurities of the Wi-Fi Protected Access (WPA) security standard.
