In 2010, Apple launched the FaceTime service for the first time, which allowed iPhone 4 owners to make video calls using an Internet connection. Shortly after, Apple launched the iPod Touch 4G, a device equipped with a front camera exactly like the iPhone 4, and the number of devices compatible with FaceTime grew considerably. In March 2011 iPad 2 joined the suite of compatible devices and now FaceTime is used by tens of millions of iDevice owners from all over the world, but how safe is a video conversation made through FaceTime? According to Apple, any conversation made through FaceTime is encrypted, but only if we are connected to a Wi-Fi network through the WPA2 Enterprise security protocol.
Pad supports WPA2 Enterprise to provide authenticated access to your enterprise wireless network. WPA2 Enterprise uses 128-bit AES encryption, giving users the highest level of assurance that their data will remain protected when they send and receive communications over a Wi-Fi network connection.
In addition to your existing infrastructure, each FaceTime session is encrypted end to end with unique session keys. Apple creates a unique ID for each FaceTime user, ensuring FaceTime calls are routed and connected properly.
Apple claims that this type of connection includes encryption for both users, but of course the call must be made by users connected to the same type of Wi-Fi network. Unfortunately, connections to Wi-Fi networks using the WEP protocol do not have encryption and theoretically could be intercepted and "broken" by people who would have the necessary technology to do this. For Apple, the problem is minor considering that intercepting a FaceTime call is very difficult and theoretically too few people would be interested in doing such a thing. However, if you are interested in keeping your video sessions away from prying eyes, use the WPA 2 Enterprise security protocol during FaceTime sessions.
In case you are wondering, FaceTime calls made via 3G are not encrypted.
