Operation Eikonal

Operation Eikonal is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Operation Eikonal rather than just read about it. In short: Operation Eikonal is a collaboration between the National Security Agency (NSA) and Bundesnachrichtendienst (BND) for the sharing of telephony and Internet data captured in Germany. It is based on an agreement that dates to 2002, and is part of the NSA operation "RAMPART-A".

Key takeaways

  • Operation Eikonal belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Operation Eikonal to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Operation Eikonal from memory before moving on to harder problems.

Reference excerpt

Operation Eikonal is a collaboration between the National Security Agency (NSA) and Bundesnachrichtendienst (BND) for the sharing of telephony and Internet data captured in Germany. It is based on an agreement that dates to 2002, and is part of the NSA operation "RAMPART-A". Surveillance started in 2003, telephony data was collected from 2004 onwards, and all Internet traffic from the Deutsche Telekom (DT) switching center in Frankfurt was captured starting in 2005. To obtain the data, the BND and DT worked together. The agents rented two rooms in the DT data center in Frankfurt where the fiber optic data cable owned by DT was spliced into, and a copy of the data was captured. DT received 6000 euros monthly for its role in giving access to data. A filtering program named Dafis was used to prevent the sharing of data from German citizens; however, that filter was estimated to be only 95% effective, meaning that 5% of data was obtained in breach of Germany's constitution (Grundgesetz). Later, during parliamentary hearings conducted on November 6, 2014, one witness claimed that the 95% figure was only correct for the initial testing and that during operation, 99% of data from German citizens was filtered out. In January 2006, the Bad Aibling branch of the BND reported to its headquarters in Pullach that the "selectors" (search terms) used by the NSA under the programme included some terms targeting the European Aeronautic Defence and Space Company (EADS) and the Eurocopter project as well as French administration. These selectors were first noticed by BND employees in 2005. Other selectors were found to target the administration of Austria. After the revelations made by whistleblower Edward Snowden the BND decided to investigate the issue; their October 2013 conclusion was that at least 2,000 of these selectors were aimed at Western European or even German interests which has been a violation of the Memorandum of Agreement that the US and Germany signed in 2002 in the wake of the 9/11 terror attacks. After reports emerged in 2014 that EADS and Eurocopter had been surveillance targets the Left Party and the Greens filed an official request to obtain evidence of the violations. The BND's project group charged with supporting the NSA investigative committee in German parliament set up in spring 2014, reviewed the selectors and discovered 40,000 suspicious search parameters, including espionage targets in Western European governments and numerous companies. The group also confirmed suspicions that the NSA had systematically violated German interests and concluded that the Americans could have perpetrated economic espionage directly under the Germans' noses. The investigative parliamentary committee was not granted access to the NSA's selectors list as an appeal led by opposition politicians failed at Germany's top court – instead the ruling coalition appointed an administrative judge, Kurt Graulich, as a "person of trust" who was granted access to the list and briefed the investigative commission on its contents after analyzing the 40,000 parameters. In his almost 300-page report Graulich concluded that European government agencies were targeted massively and that Americans hence broke contractual agreements. He also found that German targets which received special protection from surveillance of domestic intelligence agencies by Germany's Basic Law (Grundgesetz) – including numerous enterprises based in Germany − were featured in the NSA's wishlist in a surprising plenitude. While the magnitude differs, there have also been problematic BND-internal selectors which have been used until end of 2013 - around two thirds of 3300 targets were related to EU and NATO states. Klaus Landefeld, member of the board at the Internet industry association Eco International, has met intelligence officials and legislators to present suggestions for improvement, like streamlining the selector system. Information on Operation Eikonal was first unveiled by Süddeutsche Zeitung, Norddeutscher Rundfunk and Westdeutscher Rundfunk on October 3, 2014. Although some documents suggested that the operation had been completed in 2008, it was revealed that in December 2012, there were still transfers of 500 million metadata per month being made. Of these 500 million datasets, 180 million were captured using XKeyscore. Austrian member of parliament Peter Pilz described the operation as "the first successful attempt at mass surveillance of European telecommunications".

Worked examples

Example 1 — a first encounter with Operation Eikonal

Start with the simplest possible case. Write down what Operation Eikonal claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Operation Eikonal before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Operation Eikonal ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Operation Eikonal

In research
Operation Eikonal appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Operation Eikonal in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Operation Eikonal is common in secondary-school and first-year university syllabi. It links to neighbouring topics Germany–United States relations, National Security Agency operations, Surveillance scandals, so understanding it makes those chapters shorter.
In everyday life
Look for Operation Eikonal outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
