Timeline BC

~ 1900 BC: Egyptian writers use non-standard Hieroglyphs in inscriptions of a royal tomb; supposedly this is not the first but the first documented example of written cryptography

1500 an enciphered formula for the production of pottery is done in Mesopotamia

parts of the Hebrew writing of Jeremiah's words are written down in "atbash", which is nothing else than a reverse alphabet and one of the first famous methods of enciphering

4th century Aeneas Tacticus invents a form of beacons, by introducing a sort of water-clock

487 the Spartans introduce the so called "skytale" for sending short secret messages to and from the battle field

170 Polybius develops a system to convert letters into numerical characters, an invention called the Polybius Chequerboard.

50-60 Julius Caesar develops an enciphering method, later called the Caesar Cipher, shifting each letter of the alphabet an amount which is fixed before. Like atbash this is a monoalphabetic substitution.

Timeline 1900-1970 AD

1913 the wheel cipher gets re-invented as a strip

1917 William Frederick Friedman starts working as a cryptoanalyst at Riverbank Laboratories, which also works for the U.S. Government. Later he creates a school for military cryptoanalysis

- 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 Enigma machine for the German Military

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 William Frederick Friedman. As the Japanese were unable to break the US codes, they imagined their own codes to be unbreakable as well - and were not careful enough.

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.

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 Java applets, so making multimedia content possible.

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 servers as possible and index the stored information. (For regularly updated lists of the 100 most popular words that people are entering into search engines, click here). No search engine can retrieve all information on the whole World Wide Web; every search engine covers just a small part of it.

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 consoling, but threatening too.

According to the Internet domain survey of the Internet Software Consortium the number of Internet host computers is growing rapidly. In October 1969 the first two computers were connected; this number grows to 376.000 in January 1991 and 72,398.092 in January 2000.
