This wave wall is in Lisbon and contributes to making the Internet safer – multimedia

A Cloudflare He came to the world for several days A new entropy wall, consisting of 50 waves in permanent movement. A Work in the Lisbon office Like a lava lamp wall at the United States headquarters, it is a painting capable of producing random data, which is essential in encryption and systems that the company uses to protect the online traffic that passes through its systems.

A Lisbon wave machineThe headquarters of the European company was responsible for the tenth, a honor for the country, its naval history and its strong connection to the sea. “The new wave machines are A new source of Entropy, which joins Lava De São Francisco, and a hanging rainbow from Austin and the Double Double Pendulus in LondonThe company explains in a note in Blog.

S. The original design of the lampsHe was born more than a decade ago, in an attempt to explore alternatives to the answers that computers can provide to provide encryption keys. “Each new key should be used by the computer to truly encrypt the dataSo that the attacker cannot discover the key and decode the data. However, the Computers are designed to provide logical and predictable outputs Based on a specific entrance, “CLODFLERE details in A. Another article.

To produce unexpected data required by strong encryptionThe computer will have to use a random data source and There is no better source of unpredictable data from the material and realistic world. From this idea came to create lamp lights. “Volcanic lava” on the lamp lamp does not take the same way twice, and therefore, a group of moving lamps is a great source of random data. “

To collect this data, The Cloudflare created a wall with about 100 lamp lamps, He installed a room and focused on the wall. Photo information taken on regular intervals is translated into a series of numbers – Each pixel has its digital value, so each image leads to a different and always guaranteed sequence. Cloudflare servers can use this information as a starting point for creating safe encryption keys.

A The idea of ​​creating a new entropy wall in Lisbon began in 2023In order to find something logical in the country and determine the local team. The original inspiration will come from the secretary games, with wave movement machines, “which were common among some members of our team.”

but The company admitted that it was easier to reach the idea than put it into practice. “Making a wave wall is a real challenge, as these games are no longer common as they were in the past and are no longer made of the size we need.”

After searching a lot, The team concluded that there are not enough wave machinesConsistent in terms of style and good performance. I also realized that the available forms were not designed to work 24 hours a day every day.

The team responsible for decorating each office literally found a Specialized rectangular wave machine (18 inches/45 cm), Creating to work without stopping. Using rotating wheels, continuous engines and one liquid formula, these machines create realistic waves similar to those in the ocean, green, blue and orange, company color.

To make this the new Interopia wall is necessary 50 relevant wheels and relevant engines, and 50 acrylic containers where the three liquids that mix to take the appearance of the wave are deposited. From the concept to implementation, it passes 15 months. The end result is a system capable of making 15 waves per minute. On a day, there are about 20,000 movements to ensure this result.

OS Cloudflare servers This provides services to improve the performance, safety and reliability of websites and applications online, Get more than 71 million http requests per secondWhich is 100 million in peak times. “Most of these requests are protected by TLS, which are based on a safe random for encryption safety,” explains the company. “The numbers numbers numbers ensure the safe numbers (CSPRng)Use Cloudflare creativity to strike high -quality entropy sources.
