Boris Hagelin
Boris Caesar Wilhelm Hagelin (2 July 1892 – 7 September 1983) was a Swedish businessman and inventor of encryption machines. Biography Born of Swedish parents in Adshikent, Russian Empire, Hagelin attended Lundsberg boarding school and later studied mechanical engineering at the Royal Institute of Technology in Stockholm, graduating in 1914. He gained experience in engineering through work in Sweden and the United States. His father Karl Wilhelm Hagelin worked for Nobel in Baku, but the family returned to Sweden after the Russian revolution. Karl Wilhelm was an investor in Arvid Gerhard Damm's company Aktiebolaget Cryptograph, established to sell rotor machines built using Damm's 1919 patent. Boris Hagelin was placed in the firm to represent the family investment. In 1925, Hagelin took over the firm, later reorganising it as Aktiebolaget Cryptoteknik in 1932. His machines competed with Scherbius' Enigma machines, but sold rather better. At the beginning of World War I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptograph
Cryptograph was a limited Swedish company developing and selling crypto machines, founded on 21 July 1916 and liquidated in 1930. It was probably the first company in the world to focus entirely on the cryptographic market. In December 1914, two Swedes; Olof Gyldén, a navy officer with an interest in cryptography; and Arvid Gerhard Damm, a Swedish engineer and inventor, met in Berlin to discuss Damm's ideas for a new type of crypto machine. Impressed, Gyldén managed to interest a group of Swedish businessmen to invest in a project to exploit Damm's ideas commercially. A patent consortium, Cryptograph, was founded in June 1915. A year later, a shareholding company with the same name was established with Gyldén as chairman and CEO. Damm was given the position of engineer and was also a shareholder. Expectations were great and sales estimated at more than 50 desktop machines and 500 handheld devices per year. However, actual sales were far below these numbers, and although Damm ...

Carl Hagelin
Carl Oliver Hagelin (born 23 August 1988) is a Swedish professional ice hockey player for the Washington Capitals of the National Hockey League (NHL). Hagelin was drafted by the New York Rangers in the sixth round, 168th overall, of the 2007 NHL Entry Draft. Hagelin has won the Stanley Cup as a member of the Pittsburgh Penguins in 2016 and 2017. He also played the most playoff games of any NHL player in the 2010s decade, with 128. He is also very fast, as shown when Hagelin, then a rookie with the Rangers, circled the rink at Ottawa's Scotiabank Place in 13.218 seconds, in contrast to Dylan Larkin skating at a record breaking time of 13.172. Internationally, Hagelin has won a silver medal with Sweden at the 2014 Winter Olympics. Playing career Amateur Prior to beginning his collegiate career, Hagelin played two seasons for Södertälje SK's team in the J20 SuperElit. During that time, he scored 44 goals and 51 assists, ranking fifth all-time in points and goals scored for Söde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crypto AG
Crypto AG was a Swiss company specialising in communications and information security founded by Boris Hagelin in 1952. The company was secretly purchased for US $5.75 million and jointly owned by the American Central Intelligence Agency (CIA) and West German Federal Intelligence Service (BND) from 1970 until about 1993, with the CIA continuing as sole owner until about 2018. The mission of breaking encrypted communication using a secretly owned company was known as " Operation Rubikon". With headquarters in Steinhausen, the company was a long-established manufacturer of encryption machines and a wide variety of cipher devices. The company had about 230 employees, had offices in Abidjan, Abu Dhabi, Buenos Aires, Kuala Lumpur, Muscat, Selsdon and Steinhausen, and did business throughout the world. The owners of Crypto AG were unknown, supposedly even to the managers of the firm, and they held their ownership through bearer shares. The company has been criticised for selling bac ...

1892 Births
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Silanus (or, less frequently, year 942 ''Ab urbe condita''). The denomination 189 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

C-52 (cipher Machine)
The ( Hagelin) C-52 and CX-52 were cipher machines manufactured by Crypto AG starting 1951/1952. These pin-and-lug type cipher machines were advanced successors of the C-38/M-209. The machine measures . The device is mechanical, but when combined with an electric keyboard attachment, the B-52, the resultant system is termed the BC-52. The B-52 is larger, measuring . The Hell 54 was a licensed copy of the C-52 by German company Hell. Structure and operation Both C and CX models are equipped with six pinwheels. In the C-52 version, these six wheels are chosen from a possible set of 12, with the number of pins on each wheel being 25, 26, 29, 31, 34, 37, 38, 41, 42, 43, 46, and 47. The C model had a fixed stepping system with a large wheel cycle due to the mutually prime factors in the pin counts. The CX-52 version has 6 pinwheels with 47 pins each and a flexible wheel movement system. The lug cage of both models contains 32 movable bars: 27 of the bars are used for encryptio ...

C-36 (cipher Machine)
The C-35 and C-36 were cipher machines designed by Swedish cryptographer Boris Hagelin in the 1930s. These were the first of Hagelin's cipher machines to feature the pin-and-lug mechanism. A later machine in the same series, the C-38, was designated CSP-1500 by the United States Navy and M-209 by the United States military, who used it extensively. In 1934, the French military approached Hagelin to design a printing, pocket-size cipher machine; Hagelin carved a piece of wood to outline the dimensions of a machine that would fit into a pocket. He adapted one of his previous inventions from three years earlier: an adding device designed for use in vending machines, and combined it with the pinwheel mechanism from an earlier cipher machine (the B-21). The French ordered 5,000 in 1935. Italy and the USA declined the machine, although both would later use the M-209 / C-38. Completely mechanical, the C-35 machine measured 6 × 4.5 × 2 inches, and weighed less than 3 pounds. A revised ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD-57
The (Hagelin) CD-57 was a portable, mechanical cipher machine manufactured by Crypto AG, first produced in 1957. It was derived from the earlier CD-55, and was designed to be compatible with the larger C-52 machines. Compact, the CD-57 measured merely 5 1/8in × 3 1/8in × 1 1/2in (13 × 8 × 3.8 cm) and weighed 1.5 pounds (680 gr). The CD-57 used six wheels. A variant is the CD-57(RT), a similar device using a one-time pad system rather than rotating wheels. The STG-61 was a licensed copy of the CD-57 by Hell. Sullivan (2002) shows how the CD-57 can be attacked using a search technique. See also * |
