What is a cryptopocalypse?

We have come a long way in cryptography and computing since the Colossus electronic computer, (above), was built at Bletchley Park, during the Second World War, to break the Lorenz cipher.

With the advances in computing technology, there is a foreseeable point in the future, possibly only ten years, when the current cryptography we use to keep our communications, information and online transaction secure and secret will be open to decryption by powerful computing systems.

Organisations are starting to think about this.

This article by Dan Goodin on Ars Technica looks at the issues and the steps organisations such as the US government’s National Institute of Standards and Technology (NIST) is doing about it.

Where NIST leads the rest of the world is sure to follow.
