The United Kingdom electronic surveillance agency GCHQ has launched a free educational app called Cryptoy, to teach secondary school children about crpytography.
The app allows teenagers to create their own encoded messages which can be shared with friends via social media, or more traditional means. The recipients can then use the app to try to decipher the messages. By using the app teenagers can learn about cybersecurity, basic encryption techniques and learn about the history of encryption. The hope is that it will increase the uptake of STEM (Science, Technology, Engineering and Maths) subjects at school.
Further details about Cryptoy can be obtained from the GCHQ website here.
At the moment Cryptoy app is only available for download to Android tablets via Google Play, but it is hoped that an iOS version for iPads will be available in 2015.
