The Tunny machine, which measured 19 by 15 by 17 high, was a cipher attachment. The instruments implemented a Vernam stream cipher. Vernam's cipher is a symmetric-key algorithm, i.e. Tunny traffic was known by Y Station operators used to listening to Morse code transmission as "new music". British cryptanalysts, who referred to encrypted German teleprinter traffic as Fish, dubbed the machine and its traffic Tunny (meaning tunafish) and deduced its logical structure three years before they saw such a machine. work on Sturgeon is described in Weirud's Bletchley Park's Sturgeon, the Fish that Laid No Eggs in a previous issue of this journal. technically they could break Tunny, by the time the messages were decoded Reworking of this section of the website is sponsored by Book Create Service who provide Self Publishing Services.

This showed that a repetition period of 41 had some Tiltman knew of the Vernam system and soon identified these Tutte did this with the original teleprinter 5-bit Baudot codes, which led him to his initial breakthrough of recognising a 41-bit repetition.

This would not have mattered had the two messages been identical, however the second time the operator made a number of small alterations to the message, such as using abbreviations, making the second message somewhat shorter. Tunny sent its messages in binary codepackets of zeroes and ones resembling the binary code used inside present-day computers.
