The GCHQ spy post has launched an Android app called Cryptoy designed to entice youngsters into trying their hand at code-breaking.
The app is available for free from the Google Play store, and an iOS version is pegged for release in 2015.
Cryptoy was designed by students on an industrial placement at GCHQ earlier this year, and focuses on four code-breaking methods: Shift, Substitution, Vigenère and Enigma.
The app is designed to uncover young people with a talent for code-breaking and code-setting, in a bid to ensure that the UK has the skilled cyber security experts it needs for the years ahead.
Robert Hannigan, the new director of GCHQ, said that the need to find people with the necessary cyber security talent is vital as the threats to the UK proliferate.
"Building maths and cyber skills in the younger generation is essential for maintaining the cyber security of the UK and growing a vibrant digital economy,” he said.
"In particular, the Cryptoy app is a colourful, interactive way for students and their teachers to explore the fascinating world of cryptography.
"I hope it will inspire further study of this key topic, which has played such an important part in our past and is an invaluable part of our future."
Cabinet Office minister Francis Maude said that using an app to find talented people to work in high-level security environments is a modern day twist on a technique that has been used before in British history.
"Famously, the government recruited winners of a Daily Telegraph cryptic crossword competition to work at Bletchley Park," he added.
"Today, I’m pleased to announce a similarly creative solution in the hunt for expertise, but with a 21st century spin."
Cryptoy works on Google's Nexus 10 and Nexus 7 tablets, and has been tested only on versions 4.1.2 and 4.4.2 of Android. So far the app has had just three reviews with an average of four stars.
