Timeline 1900-1970 AD 1913 the wheel cipher gets re-invented as a strip 1917 - an AT&T-employee, Gilbert S. Vernam, invents a polyalphabetic cipher machine that works with random-keys 1918 the Germans start using the ADFGVX-system, that later gets later by the French Georges Painvin - Arthur Scherbius patents a ciphering machine and tries to sell it to the German Military, but is rejected 1919 Hugo Alexander Koch invents a rotor cipher machine 1921 the Hebern Electric Code, a company producing electro-mechanical cipher machines, is founded 1923 Arthur Scherbius founds an enterprise to construct and finally sell his late 1920's/30's more and more it is criminals who use cryptology for their purposes (e.g. for smuggling). Elizabeth Smith Friedman deciphers the codes of rum-smugglers during prohibition regularly 1929 Lester S. Hill publishes his book Cryptography in an Algebraic Alphabet, which contains enciphered parts 1933-1945 the Germans make the Enigma machine its cryptographic main-tool, which is broken by the Poles Marian Rejewski, Gordon Welchman and Alan Turing's team at Bletchley Park in England in 1939 1937 the Japanese invent their so called Purple machine with the help of Herbert O. Yardley. The machine works with telephone stepping relays. It is broken by a team of 1930's the Sigaba machine is invented in the USA, either by W.F. Friedman or his colleague Frank Rowlett - at the same time the British develop the Typex machine, similar to the German Enigma machine 1943 Colossus, a code breaking computer is put into action at Bletchley Park 1943-1980 the cryptographic Venona Project, done by the NSA, is taking place for a longer period than any other program of that type 1948 Shannon, one of the first modern cryptographers bringing mathematics into cryptography, publishes his book A Communications Theory of Secrecy Systems 1960's the Communications-Electronics Security Group (= CESG) is founded as a section of Government Communications Headquarters (= GCHQ) late 1960's the IBM Watson Research Lab develops the Lucifer cipher 1969 James Ellis develops a system of separate public-keys and private-keys |

Association for Progressive Communication (APC) The APC is a global federation of 24 non-profit Internet providers serving over 50,000 NGOs in 133 countries. Since 1990, APC has been supporting people and organizations worldwide, working together online for social, environmental and economic justice. The APC's network of members and partners spans the globe, with significant presence in Central and Eastern Europe, Africa, Asia and Latin America. History Between 1982 and 1987 several independent, national, non-profit computer networks emerged as viable information and communication resources for activists and NGOs. The networks were founded to make new communication techniques available to movements working for social change. In 1987, people at GreenNet in England began collaborating with their counterparts at the Institute for Global Communications (IGC) in the United States. These two networks started sharing electronic conference material and demonstrated that transnational electronic communications could serve international as well as domestic communities working for peace, human rights and the environment. This innovation proved so successful that by late 1989, networks in Sweden, Canada, Brazil, Nicaragua and Australia were exchanging information with each other and with IGC and GreenNet. In the spring of 1990, these seven organizations founded the Association for Progressive communications to co-ordinate the operation and development of this emerging global network of networks. Strategies and Policies The APC defends and promotes non-commercial, productive online space for NGOs and collaborates with like-minded organizations to ensure that the information and communication needs of civil society are considered in telecommunications, donor and investment policy. The APC is committed to freedom of expression and exchange of information on the Internet. The APC helps to build capacity between existing and emerging communication service providers. The APC Women's Networking Support Program promotes gender-aware Internet design, implementation and use. Through its African members, the APC is trying to strengthen indigenous information sharing and independent networking capacity on the continent. Members of APC develop Internet products, resources and tools to meet the advocacy, collaboration and information publishing and management needs of civil society. Recent APC initiatives have included the APC Toolkit Project: Online Publishing and Collaboration for Activists and the Mission-Driven Business Planning Toolkit. The APC also runs special projects like the Beijing+5, which shall enable non-governmental organizations to actively participate in the review of the Beijing Platform for Action. |

Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network. http://www.it.kth.se/docs/early_net/ |

World Wide Web (WWW) Probably the most significant Internet service, the World Wide Web is not the essence of the Internet, but a subset of it. It is constituted by documents that are linked together in a way you can switch from one document to another by simply clicking on the link connecting these documents. This is made possible by the Hypertext Mark-up Language (HTML), the authoring language used in creating World Wide Web-based documents. These so-called hypertexts can combine text documents, graphics, videos, sounds, and Especially on the World Wide Web, documents are often retrieved by entering keywords into so-called search engines, sets of programs that fetch documents from as many Among other things that is the reason why the World Wide Web is not simply a very huge database, as is sometimes said, because it lacks consistency. There is virtually almost infinite storage capacity on the Internet, that is true, a capacity, which might become an almost everlasting too, a prospect, which is sometimes According to the Internet domain survey of the |
