Looks like there are lots of interest in the academia to further push Android to the limit. A research team from Google, George Mason University and the National Security Agency developed a kernel for Android 3.0 (Honeycomb) that could be used for military operations and emergency response. In order for a software to be used in defence industry it needs to fulfill certain certification requirements, in this case it’s called Federal Information Processing Standard 140-2 certification and this strict requirement is what makes software secured and reliable. The kernel is in the final stages of certification testing and will be used in smart phones or tablet wireless devices to troops in combat operations.
Looks like the white house is also interested to use the kernel to create a secure national wireless network and also to use Android devices, replacing Blackberry for the executive branch. Looks like they are targeting to complete by March 2012.
