Like many other European electronics companies,
Siemens developed
a number of cipher machines over the years. The most famous one is
probably the T-52,
also known as the Geheimschreiber, that was
used by German High Command during WWII. After the war, Siemens
developed a series of mixer-machines based on the Vernam principle.

The T-52 was one of the strongest cipher machines used by the
Germans during WWII. Is is based on the Vernam principle, whereby
the digital 5-bit code of a teletype is mixed with a 5-bit random
number. The random number generator, however, is built-in and is
based on mechanical wheels, notches and pins.
