Who better to learn encryption from than the people who have actively tried to build vulnerabilities into encryption? Nobody, says the GCHQ, the British NSA equivalent that has released a free Android app called Cryptoy to teach children the basics of encryption. The app, designed for tablets, focuses on four basic techniques and allows users to create encrypted messages for sharing to friends to decode.
Over the years, Google has been shoring up security on Android in a bid to make the operating system more attractive to governments and businesses, and to reduce the threat of malware for regular users. Unfortunately, these changes often come at the expense of flexibility in our beloved platform. As we close in on the next major release of Android, due to be announced next month, SuperSU developer Chainfire has discovered a set of commits to the Android Open Source Project (AOSP) that may seriously impact some of the functionality currently enjoyed by many root users.
This is a pretty wild piece of news. Google, George Mason University, and the NSA are working to make Android the most secure OS out there. They're developing a "hardened" kernel so Android can pass all the necessary red tape to be deployed for government use. By 2012 they expect Android to be good enough for classified communication, and eventually they'll hit a higher security clearance level than BlackBerrys. Poor BlackBerry, security was one of the last things they had left.
