First European medieval university is established in Bologna.

The first of the great medieval universities was established in Bologna. At the beginning universities predominantly offered a kind of do-it-yourself publishing service.

Books still had to be copied by hand and were so rare that a copy of a widely desired book qualified for being invited to a university. Holding a lecture equaled to reading a book aloud, like a priest read from the Bible during services. Attending a lecture equaled to copy a lecture word by word, so that you had your own copy of a book, thus enabling you to hold a lecture, too.

Basics: Protected Works

Usually the subject matter of copyright is described as "literary and artistic works" - original creations in the fields of literature and arts. Such works may be expressed in words, symbols, pictures, music, three-dimensional objects, or combinations thereof. Practically all national copyright laws provide for the protection of the following types of works:

Literary works: novels, poems dramatic works and any other writings, whether published or unpublished; in most countries also computer programs and "oral works"

Musical works

Artistic works: whether two-dimensional or three-dimensional; irrespective of their content and destination

Maps and technical drawings

Photographic works: irrespective of the subject matter and the purpose for which made

Audiovisual works: irrespective of their purpose, genre, length, method employed or technical process used

Some copyright laws also provide for the protection of choreographic works, derivative works (translations, adaptions), collections (compilations) of works and mere data (data bases); collections where they, by reason of the selection and arrangement of the contents, constitute intellectual creations. Furthermore in some countries also "works of applied art" (furniture, wallpaper etc.) and computer programs (either as literary works or independently) constitute copyrightable matter.

Under certain national legislations the notion "copyright" has a wider meaning than "author's rights" and, in addition to literary and artistic works, also extends to the producers of sound recordings, the broadcasters of broadcasts and the creators of distinctive typographical arrangements of publications.

Legal Protection: TRIPS (Trade-Related Aspects of Intellectual Property Rights)

Another important multilateral treaty concerned with intellectual property rights is the TRIPS agreement, which was devised at the inauguration of the Uruguay Round negotiations of the WTO in January 1995. It sets minimum standards for the national protection of intellectual property rights and procedures as well as remedies for their enforcement (enforcement measures include the potential for trade sanctions against non-complying WTO members). The TRIPS agreement has been widely criticized for its stipulation that biological organisms be subject to intellectual property protection. In 1999, 44 nations considered it appropriate to treat plant varieties as intellectual property.

The complete TRIPS agreement can be found on: http://www.wto.org/english/tratop_e/trips_e/t_agm1_e.htm

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

Digital Signatures, Timestamps etc

Most computer systems are far from being secure.
A lack of security - it is said - might hinder the developments of new information technologies. Everybody knows electronic transactions involve a more or less calculated risk. Rumors about insecurity let consumers doubt whether the commodity of e-commerce is bigger or its risks. First of all the market depends on the consumer's confidence. To provide that another application for public key cryptography gets essential: the digital signature, which is used to verify the authenticity of the sender of certain data.
It is done with a special private key, and the public key is verifying the signature. This is especially important if the involved parties do not know one another. The DSA (= Digital Signature Algorithm) is a public-key system which is only able to sign digitally, not to encrypt messages. In fact digital signature is the main-tool of cryptography in the private sector.

Digital signatures need to be given for safe electronic payment. It is a way to protect the confidentiality of the sent data, which of course could be provided by other ways of cryptography as well. Other security methods in this respect are still in development, like digital money (similar to credit cards or checks) or digital cash, a system that wants to be anonymous like cash, an idea not favored by governments as it provides many opportunities for money laundry and illegal transactions.

If intellectual property needs to be protected, a digital signature, together with a digital timestamp is regarded as an efficient tool.

In this context, the difference between identification and authentication is essential. In this context smartcards and firewalls are relevant, too.

A lot of digital transactions demand for passwords. More reliable for authentication are biometric identifiers, full of individual and unrepeatable codes, signatures that can hardly be forged.

Cryptography's Terms and background

"All nature is merely a cipher and a secret writing."
Blaise de Vigenère

In the (dis-)information age getting information but at the same time excluding others from it is part of a power-game (keeping the other uneducated). The reason for it eventually has found an argument called security.
Compared to the frequency of its presence in articles, the news and political speeches security seems to be one of the most popular words of the 90's. It must be a long time ago when that word was only used for and by the military and the police. Today one can find it as part of every political issue. Even development assistance and nutrition programs consider it part of its work.
The so-called but also real need for information security is widespread and concerning everybody, whether someone uses information technology or not. In any case information about individuals is moving globally; mostly sensitive information like about bank records, insurance and medical data, credit card transactions, and much much more. Any kind of personal or business communication, including telephone conversations, fax messages, and of course e-mail is concerned. Not to forget further financial transactions and business information. Almost every aspect of modern life is affected.
We want to communicate with everybody - but do not want anybody to know.

Whereas the market already depends on the electronic flow of information and the digital tools get faster and more sophisticated all the time, the rise of privacy and security concerns have to be stated as well.
With the increase of digital communication its vulnerability is increasing just as fast. And there exist two (or three) elements competing and giving the term digital security a rather drastic bitter taste: this is on the one hand the growing possibility for criminals to use modern technology not only to hide their source and work secretly but also to manipulate financial and other transfers. On the other hand there are the governments of many states telling the population that they need access to any kind of data to keep control against those criminals. And finally there are those people, living between enlightening security gaps and at the same time harming other private people's actions with their work: computer hackers.
While the potential of global information is regarded as endless, it is those elements that reduce it.

There is no definite solution, but at least some tools have been developed to improve the situation: cryptography, the freedom to encode those data that one does not want to be known by everybody, and give a possibility to decode them to those who shall know the data.

During the last 80 years cryptography has changed from a mere political into a private, economic but still political tool: at the same time it was necessary to improve the tools, eventually based on mathematics. Hence generally cryptography is regarded as something very complicated. And in many ways this is true as the modern ways of enciphering are all about mathematics.

"Crypto is not mathematics, but crypto can be highly mathematical, crypto can use mathematics, but good crypto can be done without a great reliance on complex mathematics." (W.T. Shaw)

RSA

The best known of the two-key cryptosystems developed in the mid-1980s is the Rivest-Shamir-Adleman (RSA) cryptoalgorithm, which was first published in April, 1977. Since that time, the algorithm has been employed in the most widely-used Internet electronic communications encryption program, Pretty Good Privacy (PGP). It is also employed in both the Netscape Navigator and Microsoft Explorer web browsing programs in their implementations of the Secure Sockets Layer (SSL), and by Mastercard and VISA in the Secure Electronic Transactions (SET) protocol for credit card transactions.

CNN

CNN is a U.S.-TV-enterprise, probably the world's most famous one. Its name has become the symbol for the mass-media, but also the symbol of a power that can decide which news are important for the world and which are not worth talking about. Every message that is published on CNN goes around the world. The Gulf War has been the best example for this until now, when a CNN-reporter was the one person to do the countdown to a war. The moments when he stood on the roof of a hotel in Baghdad and green flashes surrounded him, went around the world.

Royalties

Royalties refer to the payment made to the owners of certain types of rights by those who are permitted by the owners to exercise the rights. The rights concerned are literary, musical, and artistic copyright and patent rights in inventions and designs (as well as rights in mineral deposits, including oil and natural gas). The term originated from the fact that in Great Britain for centuries gold and silver mines were the property of the crown and such "royal" metals could be mined only if a payment ("royalty") were made to the crown.

WTO

An international organization designed to supervise and liberalize world trade. The WTO (World Trade Organization) is the successor to the General Agreement on Tariffs and Trade (GATT), which was created in 1947 and liberalized the world's trade over the next five decades. The WTO came into being on Jan. 1, 1995, with 104 countries as its founding members. The WTO is charged with policing member countries' adherence to all prior GATT agreements, including those of the last major GATT trade conference, the Uruguay Round (1986-94), at whose conclusion GATT had formally gone out of existence. The WTO is also responsible for negotiating and implementing new trade agreements. The WTO is governed by a Ministerial Conference, which meets every two years; a General Council, which implements the conference's policy decisions and is responsible for day-to-day administration; and a director-general, who is appointed by the Ministerial Conference. The WTO's headquarters are in Geneva, Switzerland.
