Simson Garfinkel presenting at CFP 2011 on "Hard Drives, Encryption, Forensics, and Privacy"

Having visited Bletchley Park last week I just had to visit the memorial to legendary WWII codebreaker Alan Turing on my brief trip to Manchester. The sculpture is by Glyn Hughes is at Sackville Gardens off Canal Street. Manchester University, where Alan worked after Bletchley Park, is behind him.

 

The cast bronze bench carries the text "Alan Mathison Turing 1912–1954" and the motto "Founder of Computer Science" as it would appear if encoded by an Enigma machine; 'IEKYF RQMSI ADXUO KVKZC GUBJ'. However this is clearly an artists impression of an Enigma encryption, rather than an actual one. As I learnt at Bletchley Park last week Enigma could not encode a letter as itself and on the bench there is a letter "U" at position 14 of both the plain-text and the cipher thus betraying it as not a true Enigma cipher.

Colossus Machine Fragment

Colossus, named for its extraordinary size, was designed by Tommy Flowers from the GPO Research Station at Dollis Hill to process German Lorenz (Tunny) messages. The first working model of Colossus arrived at Bletchley Park in 1944.

Colossus was the first large-scale electronic digital computer and only a few original Colossus fragments survive.

Lorenz Schlusselzusatz SZ42 Ciper Attachment

Manufactured by the Lorenz Electronics and Electrical Company, these cipher machines were used for message passed between German Army Field Marshals and Generals at the front lines and their High Command in Germany. Enciphered messages (traffic) enciphered by this machine were given the codename Tunny by Bletchley Park.

This machine was captured from Field Marshal Kesselring’s communications vehicles by the Allies in 1945 and brought to Beaconsfield in the UK for investigation and operational testing.

Lorenz T-32 Springschreiber

A 1930s teleprinter manufactured by the German Lorenz Electronics and Electrical Company. A teleprinter is an electromechanical typewriter used to send and receive typed information in the form of teleprinter code. The Lorenz cipher attachment (Tunny) was an ‘in-line’ machine that was attached to a standard teleprinter such as the Lorenz T-32. Messages were typed by the sender in plain text on his teleprinter and appeared again as plain text on the receivers teleprinter. The sender and receiver would not normally see the cipher text produced by the cipher attachment.

Siemens & Halske Fernschreiber 68-F

A wartime teleprinter manufactured by the German Siemens & Halske Electrical Engineering Company.

The Fernschreiber is a 5 unit tape cutting machine, used to tape up the plain text message before it was fed into the Lorenz cipher attachment (Tunny). The Lorenz cipher attachment was an ‘in-line’ machine that was attached to a teleprinter such as this.

A real life Enigma machine. Pretty impressive machine to see.

Alan Turing’s office

Here at his desk in Hut 8, Turing took the lead on breaking naval Enigma ciphers - something few thought could ever be done. His mathematical skills also enabled him to break other ciphers, including the complex Lorenz cipher where he used a method that became known as Turingery. Together with he’s fellow Codebreaker Gordon Welchjman, he developed the Bombe machine to help speed up the codebreaking process.

Tankards

Pewter tankards owned by Alan Turing and commemorating the King’s College Boat Club Trial Eights in 1931 and 1934. The wear around the handles shows that Alan enjoyed using them during his time at Cambridge. These tankards were given by Sara Turing (Alan’s mother) to her granddaughter, Shuna and are a treasured family possession.
