India creates a quantum random number generator commissioned by the military - DRDO announced a "revolutionary" invention

In India, announced a "revolutionary" invention of scientists working in the structures of DRDO - Defense Research and Development Organization. Reports say that a group of scientists in Mumbai, commissioned by the military, managed to create a quantum random number generator with conversion to binary code. According to the Indian press, until now it was believed that it was impossible to create a generator of "ideal randomness" by the known methods.

To begin with, about the reason why such studies were ordered by the defense structure. The fact is that the use of a quantum random number allows you to bring data exchange to a completely different level of security. We are talking, among other things, about cryptography - methods of encrypting certain data.

Using the generation of the so-called "true" random number (in this case, the quantum version) allows you to create "keys" to protect information during its transmission. In addition, when using this generation, the capabilities of robotics and artificial intelligence are significantly increased. That is why such studies are of interest to the military. Speaking about promising military technology, the use of robotic platforms based on artificial intelligence is increasingly mentioned.

The QRNG random number generation technology developed in the Mumbai laboratory has an important feature. It also allows you to translate this information into a binary sequence familiar to computer technology at high speed. A speed of about 150 kbit / s with the so-called post-processing of data - at the initial stages of testing is named.

From the message of Indian scientists:

QRNG is based on the principle that if a single photon hits a balanced beam splitter, it will randomly occupy any of the beam splitter's output paths. The path taken by the photon is random, the randomness is converted into a sequence of binary digits called bits.

The Defense Research and Development Organization of India announced that it has successfully tested the technology for transmitting data using quantum "keys" over a 12 km fiber optic link.

In addition to military goals, this development also has broad "civilian" prospects - including in the field of financial data protection - for example, performing secure banking operations, creating "super passwords", developing artificial intelligence in managing large amounts of data.

According to this principle, it seems like the GSM communication standard is protected, if I remember. The impossibility of selecting keys mathematically, but only by the method of generating random numbers. Now, it turns out, it is possible not only to encrypt, but also to hack into cellular networks with impunity, and calmly use them for their own purposes - stealing information, throwing up the necessary information, blocking subscribers - massive. ...

A "quantum random number generator" is a radioactive sample, a Geiger counter next to it and a signal sensor. Such things have existed for a long time. Yes, they do give truly unpredictable random numbers. The photon variant seems to generate more of these numbers.

by generating random numbers.

Not random numbers, but pseudo-random... Until recently, all RNGs worked according to a certain algorithm, that is, the "randomness" of the generated numbers was mathematically predetermined. This is fundamentally important for encryption: if there is an algorithm, then it can be identified. If the algorithm is discovered and understood, then decryptors can use it to generate a "gamma" that will be the key to the cipher.

Colleagues, Happy New Year!

[Momotomba]

Gamma is generated based on the key. The algorithm for generating the gamma is known, the encryption algorithm is also known ... It is important that the resulting text does not differ from white noise. And this is not possible in principle ...

[Brylevsky]

Gamma is generated based on the key.

Are you confusing anything? "Gamma" and the cipher key are absolutely not related to each other ... The cipher key can be, for example, the word "release", and so, in order not to pick it up by brute force, a one-time "gamma" is used, which, in turn, "encrypts" the key itself, which encrypts the text. Any book containing a suitable number of digits of the required length in its text can serve as a "gamma generator". The addressee and the sender must each have one copy of such a book and agree on an unambiguous definition of which page, which paragraph and which line on this page they will use this time. For this purpose, various technical reference books or, even better, astronomical almanacs or tables of logarithms are well suited. But if such a book falls into the hands of the decoders, then the selection of a used "scale" for them will only be a matter of time. So, step by step, all correspondence will be opened ... To prevent this, encryption notebooks were invented. According to the rules, the used notebook page must be immediately destroyed - burned. This guarantees sufficient cryptographic strength. Written (manual) encryption is organized according to this principle, without the use of a computer. Perhaps you meant some other encryption, but I was behind the times. Best regards, and Happy New Year

QRNG is based on the principle that if a single photon hits a balanced beam splitter, it will randomly occupy any of the beam splitter's output paths. The path taken by the photon is random

Random, not mathematically predetermined. All random number generators work on the basis of the algorithm embedded in them, that is, the generation of "random" numbers is not at all random in nature. And now it's random, because the choice of the path along which the photon will move is determined only by probability theory... Consequently, a message encrypted with such a "key" can also be decrypted with a certain probability, which is not one ... Because it is impossible to predict which path the "photon-decryptor" will take to repeat the path of the "photon-cipher key". No path repeat - no gamma break.

[SHURUM -BURUM]

Without thinking, I will name the numbers that come to mind. And believe me, there is no algorithm or predetermination! And the path of the photon and the direction of my thought are not predictable. I can work as a random number generator, for a good reward, preferably remotely. Happy New Year, everyone!!!

And the “gamma” generated by you, you, as the addressee, will send - send it by e-mail, carrier pigeon, or something else? If the sequence of digits can be intercepted, then it will be intercepted, it is only a matter of time ...

Is this so that missiles and shells hit right on target?

[Brylevsky]

No. That there was no need to use encryption notebooks. The discovery of such a notebook during a search of a suspect in intelligence activity is an extremely strong fact (nail) in the lid of a suspect in espionage. I am already silent about the fact that if the page of the notebook with which the report was encrypted was not destroyed, then with its help it will be opened all correspondence. Richard Sorge burned out on this ... however, he did not use encryption pads, but an ordinary book, but this does not change the essence of the matter.

[Land defence]

Yes, there is not much difference. Now, during the search, they will look for a cipher "flashlight" (or whoever gives out photons there) and the suspect will burn out anyway. Technology is moving forward on both sides.

[nobody75]

The fact of the matter is that neither a torch nor a single photon detector will help the investigation. You cannot enter this river twice. And the generator mentioned by the author can be used to generate a one-time Vernam key. The flashlight is used for quantum key distribution.

And the Indians began to fuss after all models (except mine) of the spread of the coronavirus began to give out nonsense.

And does Lukashenka, in the context of the massive violation of quarantine by Belarusians at demonstrations, show a lower incidence rate in the country compared to the Russian Federation and Ukraine, revealing chains of cases? In China, less than 500 people per 1500 people are now sick with coronavirus. In addition, there is a clear dependence of morbidity on air temperature, daylight hours and the intensity of sunlight.

Friends, commenting on Pashinyan's coming to power, already predicted difficult trials for Armenia. Perhaps Covid signaled the beginning of the decline of the West and the dominance of East Asia. I mean that quarantine is a proven remedy against epidemics, which temporarily lost its position in the era of the effectiveness of antibiotics.

And like all tested folk remedies, it has not found scientific confirmation of its effectiveness, from the point of view of evidence-based medicine.

The fact that there are 90 patients in China in 000, and 2020 million in Russia, 3 million in the United States, half a million in small Israel does not prove the effectiveness of quarantine measures to you? In Vietnam, in general, there are only 20 people, although this country, since the beginning of the epidemic, has exported its fellow citizens from all over the world to their homeland. In the DPRK, the coronavirus did not come at all. In addition, pomegranates, black mountain ash, rejection of coffee, sugar, chocolate really dramatically increase immunity and weaken complications on the cardiovascular system. In Japan, a country with a Western economy, where it is customary to wear masks during influenza epidemics, only 1500 thousand have had coronavirus.

[nobody75]

And you, excuse me, have all 1,4 billion Chinese seen CT scan results? I will secretly open my eyes to these statistics - the figures you cite reflect not the effectiveness of quarantine measures, but the availability of tomography.

In Russia, the presence of coronavirus is determined not by tomography, but by an antibody test. Tomography allows you to determine the degree of lung damage, regardless of the cause, and detects severe cases. She will not reliably tell the cause of lung damage, poisoning, smoking, germs or viruses. 160 million tests were done in China, 92 million in Russia, 260 million in the United States. That is, their number does not differ much from country to country. It's just that in the PRC, when a patient appears, all possible carriers are tested with a large margin and very quickly. Russia and the United States could not afford this. Therefore, in the United States, Covid kills as many people in 3 days as in China during the entire epidemic. For Russia, this is 10 days.

The test can be performed by a nurse within 30 seconds contacting the patient. It is impossible to find so many competent pulmonologists who must be in the room where the tomograph is located and where patients and diagnosed patients must be brought in to conduct 260 million tests in the United States in six months. If in the United States everyone was checked on a tomograph, then all the pulmanologists there would have had covid, and 3% of them would have died from covid. In Russia, when a patient is admitted, an X-ray is taken. However, in Lobnya, those who had been ill and recovered at the time of admission with covid were identified only with the help of a test and not an X-ray.

The PRC has shown its ability to successfully withstand the coronavirus. We do not know all the reasons for this success. It is unwise to boil everything down to disbelief in China's ability to fight the coronavirus. For example, in the spring of 2020, China was the largest buyer of meltblown in Russia. For this, the Chinese involved translators even from machine tool firms. For example, only at a time through CTB Co., Ltd the Chinese bought 7 tons of meltblown for about half a million yuan. And this is not all purchases through this meltblown company in Russia in April 2020. As you know, only masks filtering the air with the help of a meltblown are able to reliably detain coronavirus. In addition, with the outbreak of coronavirus in Beijing in June 2020 (200 people managed to get sick per day), the Chinese identified the area of ​​the spread of coronavirus in one day (a market in Beijing, a warehouse in the market, fish in this warehouse). It was no easier than diagnosing polonium 210-based poisons or 3rd generation nerve poisons, and for this you need to have at least modern and sophisticated and sensitive diagnostic equipment. If Europe, Israel, Russia and the United States were able to fight the coronavirus just as effectively, they would do it.

[nobody75]

As you know, only masks filtering the air using a meltblown are able to reliably trap coronavirus.

Not capable ... not any masks ... Although he is big, but still a virus. China itself officially states that outbreaks of covid occurred simultaneously around the world and denies the Chinese origin of the virus.

The coronavirus is large enough, not very contagious. Don't you know that in Venice, alcohol-impregnated masks provided 100% protection for the Mortus brigade during the Great Plague? With the help of masks, they also fought the Spanish flu epidemic in 1918. In Japan, since the 1970s, it has been customary to wear masks during a flu epidemic, which makes it possible to reduce the incidence of this infection tenfold. 100% wearing masks both sick and healthy reduces the incidence of coronavirus by about 30 times. Doctors wear masks during operations for a reason. Did stupid people in 1970 teach Soviet schoolchildren in CWP lessons how to make and wear masks in the case of biological warfare? In the trauma department of Lobnya, the faith of doctors in medical masks was so great that during the spring outbreak of the virus, not a single doctor from this department took sick leave and did not quit.

By the way, Monte Carlo owes its highly developed gambling zone to the famous English businessman Basil Zakharov. In his declining years he loved to go to casinos. The most famous entrepreneur mentioned above was brought by the deal on the unfriendly takeover of the firm of Hiram Maxim for the production of machine guns. After Zakharov survived the inventor from the company he founded, he organized the supply of Maxim machine guns to all European armies. And he squandered the money he earned by overwork in the casino.
