Rebirth: Fight For Life

   Chapter 772 Difficult decryption

  The time has come to the early morning of July 26th.

   Acting in a full set, Gu Song's figure is basically always in the live broadcast screen.

   There are not a few people watching the live broadcast.

   Now, they also believe that the progress is indeed what the official conveyed: a decryption model has been established for the encrypted information. The decryption method of this piece of information is indeed based on a quantum algorithm.

   Now decrypting it involves the need to determine a total of 10 unknown constants.

   There is no doubt that cracking work has blocked the vast majority of teams around the world.

   To crack quantum encryption as quickly as possible, quantum computers are needed.

   Those who watch the live broadcast are all thinking in their hearts: If there is no breakthrough in quantum computing technology, what will the consequences be like?

  …

   In the Oval Office, Tang Commander's bags under his eyes became heavier.

  Cassini's observation of the signal source will take a month.

   But now, it is the domestic order problem that involves a lot of his energy.

   That's right, you don't need to announce it yourself, the information that Cassini has the best chance of observing this signal source has also been inferred by various people.

   However, there are also some sand sculptures who just say that this will expose Ami's existence first and make Ami suffer the first wave of attacks.

   Really speechless, no matter what its position on the orbit of Titan, people have clearly been sending messages to the earth in a constant direction. Do these ostrich-shaped sand sculptures think they can hide?

   Can't you support our work like across the sea?

   Don't you know that even across the sea, a "sincere invitation" has been sent to us to share Cassini's data?

   Originally, it was a rare time to hold the initiative in the past few years.

   Now, the decryption model of the encrypted signal was indeed established by the other party first.

   But so what?

  Although the opponent’s computing power is awesome, but there are 10 unknown constants, what should they do?

   This is not a very simple algorithm. It only needs to be exhausted and can be solved by taking advantage of the unique advantages of quantum computers in this problem.

   First, this is a combination of 10 unknown constants. It has to be accurate for everything, including the exact order of each.

  Secondly, this itself is a quantum encryption, how can it be broken so easily?

   So obviously, as the Cassini project leader said before, the clue is in the source of the signal.

  Why don't these sand sculptures understand?

   Alien exam questions, so easy to answer?

   Is this just a matter of computing power?

   "Based on Cassini's first shot, we determined that the size of the signal source was not large. As we all know, Cassini has reached the end of its mission and has run out of fuel. So..."

  Commander Tang watched the TV as NASA's new administrator was explaining to the public what Ami's next plan was and why the details couldn't be announced as soon as possible.

   Because where can there be details so quickly?

   Don't these sand sculptures understand billions of kilometers and can only transmit a few hundred bytes per second?

   Commander Tang stood up and paced.

   Now we can only wait for now.

   He didn't want to worry about other issues immediately, so he tuned to the Chinese live channel.

   It's the only joy to see how they decipher the headaches.

  …

   "We can't really be exhaustive! Even if we have the computing power of the Quantum Supercomputing Center, we can't do it. Also, time is more precious."

"Narrow down the scope first. No matter what the shape of their civilization is, at least it has been proved that this is a problem that needs to be solved with mathematics. These ten constants cannot be meaningless things. At least, we need to first put Some of the constants that we humans have learned about are listed and narrowed down."

"No, there are too many possibilities," growled a polar bear scientist, "not necessarily just constants in science like pi, the Pythagorean constant, e. And, even if it's just a scientific constant, there is mathematics , physical, chemical... all kinds of add up, pick 10 from it, and arrange it... This is crazy. What's the basis for us to narrow it down?"

   "Have there been any patterns in the signal since we received the data? Are there any clues?"

"It's just repeating. But putting the total length of data, the repeating time interval, etc. into the calculation as constants, there is no result. I think, maybe Ami is right, the clue is in the signal source itself. Or, we Looking forward to Cassini sharing data. Or, we'll start our own exploration mission as soon as possible. At least for now, it's not aggressive yet, maybe it's a peaceful exchange."

  “…”

  Although it is a wide-angle lens that is placed in a corner and does not move, it can still record relatively loud sounds.

  When the debate is getting bigger and bigger, people find that even with a quantum supercomputing center, it is difficult to decrypt this information.

   Just like in the era of RSA algorithm, it is almost impossible for the top encryption algorithm to be broken, this encryption algorithm...may be equally difficult.

  The people who watched the live broadcast until midnight felt the anxiety from the screen.

   On the other side of the ocean, Commander Tang naturally felt much more comfortable.

   is true, things are going as expected.

   He stretched out and turned off the TV, and started what the processor was supposed to do today.

   Opposite is the night, here is the day, the sun is shining brightly.

  …

   In the room, Gu Song sat on the side without speaking.

   He seemed to be thinking.

   He was indeed thinking.

   This is an exam question initiated by him, and he is observing the reactions of his compatriots.

   Of course, this is also the beginning of the final phase of the Flint Project.

   In this long ten years, in the first stage, he accumulated his own strength and influence. At the same time, he has also started to improve the industrial support capabilities of this era from all aspects, and the technical level that makes the whole plan a little more reasonable.

   In the second stage, it starts to build the Flint Space City.

   Now, the construction of Flint Space City has entered a certain scale, and it is time to prepare for it to set sail.

   He stood up and said, "Let's not talk about this for now, we might as well reason from a logical point of view."

   The room fell silent, listening to him.

  Gu Song walked to an electronic whiteboard and started drawing with an electronic pen.

   "We're on Earth, and it's in the orbit of Titan."

   With the outline of his electronic pen, the artificial intelligence system behind it automatically recognized its semantics. On the electronic whiteboard, what he sketched was a very precise image of the Earth and Saturn.

   "First of all, we all agree that this signal was sent on purpose, right?"

"At present, it seems that everything is peaceful. Then let's turn it around. If we want to communicate with another alien civilization whose language may be completely different, we still use electromagnetic waves, why do we encrypt it? The purpose of our encryption is definitely not for Not being cracked is precisely for communication."

"So, I think these ten constants are not for us to decipher this encrypted information. Is it possible that the process of obtaining these ten constants is itself the information to be communicated. It is even said that it is like a kind of Like a dictionary of languages, does it allow us to understand their language through some process, some form?"

"Like what we marked on Voyager 1's metal disk, where we indicated binary. So now, we at least know that on quantum algorithms, this signal can create a stable decryption model, isn't that right? A sign?"

   "Isn't it also a sign to use the form of electromagnetic waves?"

   "Is the frequency it uses also a sign?"

"Even, we use the various data we guessed before." Gu Song pointed to the screen, "The distance between Titan and the earth, the mass of Titan, the mass of the earth... When we use various information we already know Is the process of substituting in and decrypting it part of the information they want to convey, a process of language learning?"

"In the end, for some safety reasons, we haven't tried to send a message to it. But in fact, it doesn't rule out that someone else has already tried. So, if the signal is further changed because of our feedback , is it the beginning of the real crack?"

  Gu Song seemed to have only expressed his thoughts, but everyone in the room was lost in thought, and some people seemed to have faintly shining eyes.

   In the eyes of those watching the live broadcast late at night, this is a real, ongoing blockbuster plot.

   The process of human beings trying to decrypt the information of extraterrestrial civilization is so difficult and complicated.

  Crossing the species, communication is not so easy.

   After all, you have no idea if the other person has such a thing as a throat and tongue.

   What if the other party itself is an energy life in the form of electromagnetic waves?
