New GCHQ Challenge for Christmas crackers

GCHQ has produced a new brain teaser to delight puzzle enthusiasts during the festive season.

Following the hugely successful cryptanalytic challenge which GCHQ staged on its website (www.gchq.gov.uk) during the summer, the same expert has devised a new puzzle which should tease and test any would-be code cracker this Christmas. The new challenge will focus on matching lists of men and women with a common purpose and then finding a missing message.

A GCHQ spokesman said: "We thought the summer challenge - based on extracts from books - would be tough, but many solvers took a few short cuts by using the Internet, so we have taken this into account by setting a higher level of difficulty this time around." He continued: "I believe this latest puzzle will be our most successful ever, especially because it coincides with the festive break. We were astonished by the huge response to the last challenge - interest seems to increase each time we do one."

Just to make things a little more interesting, GCHQ will be offering copies of 'Big Bang' the latest book by Simon Singh, the well known mathematician and code expert, to six successful solvers whose names will be drawn from a hat.

Answers to the challenge (which is launched today) and names of prize winners will appear on the website on Monday 7 February 2005.

GCHQ is on the lookout for talent in a variety of disciplines ranging from IT, communications, electronics engineering, physics, mathematics, languages and information science to intelligence analysis, purchasing and fast-track management training. Details of recruitment drives are available on the web site.
