Cryptography challenge

Plus reported some time ago that the Secure Hash Algorithm SHA-1, on which the security of all electronic communication depends, came dangerously close to being cracked, thanks to the work of the Chinese mathematician Xiaoyun Wang (see The dangers of cracking hash).

Now the US National Institute of Standards and Technology is responding. This year it will launch a competition to find a new algorithm to replace SHA-1. Cryptographers sharpen your pencils!
