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

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

There are not a few people who watch the live broadcast.

Now, they also believe that the progress is indeed officially delivered: a decryption model has been established for encrypted messages. The way this information is decrypted is indeed based on quantum algorithms.

Now decrypting it involves determining a total of 10 unknown constants.

There is no doubt that cracking efforts have blocked the vast majority of teams around the world.

If you want to crack quantum encryption as soon as possible, you have to have a quantum computer.

People who watched the live broadcast all thought in their hearts: If there is no breakthrough in quantum computing technology now, what will the consequences become?

……

In the Oval Office, Commander Tang's eye bags were even heavier.

Cassini's observations of the signal source had to wait a month.

But now, it is the issue of order in the country that is consuming a lot of his energy.

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

However, there are also some sand sculptures who insist that this will be the first to expose Ami's existence, causing Ami to suffer the first wave of attacks.

It's really speechless, no matter where it is in the orbit of Titan, people have clearly sent information to the earth constantly, can this group of ostrich-shaped sand sculptures still think they can hide?

Can't it be like the other side of the sea to support our work?

Don't you know that even across the sea, there is a "sincere invitation" from us to share Cassini's data?

It was supposed to be a rare time for a few years to take the initiative.

Now, the decryption model of encrypted signals is indeed the first to be established by the other party.

But so what?

Although the other party's computing power is awesome, but there are 10 unknown constants, what should they do?

Again, this is not a very simple algorithm, and it only needs to be exhaustive, taking advantage of the unique advantages of quantum computers in this problem.

First of all, this is a combination of 10 unknown constants. It has to be accurate in every single one, including the order of each one.

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

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

Why don't these sand sculptures understand?

Alien exam questions, are they so easy to answer?

Where is this just a matter of computing power?

"Based on Cassini's first shooting, we determined that the size of the source was not large. As we all know, Cassini has reached the end of its mission, and there is not much fuel left. So ......"

Commander Tang watched the TV as NASA's new administrator explained to the public what Aramco was planning to do next and why it couldn't be released now as soon as possible.

Because where can there be details so quickly?

Don't these sand sculptures understand more than a billion kilometers and can only transmit a few hundred bytes of things in a second?

Commander Tang stood up and paced.

For now, we can only wait.

didn't want to immediately enter the state of worrying about other problems, so he tuned to the live broadcast channel of Huaguoren.

It's the only pleasure to see how they have a headache and how to decipher it.

……

"We can't really do exhaustively! Even if we have the computing power of the quantum supercomputing center, we can't do that. And it's time that's even more precious. ”

"Let's narrow it down first. Whatever the form of their civilization, it has now at least been proven that this is a problem that needs to be solved mathematically. These ten constants can't be meaningless. At the very least, we need to narrow down some of the constants we humans already know. ”

"No, there are too many possibilities. "It doesn't have to be just scientific constants like pi, Pythagorean constants, and e." Moreover, even if it is only a scientific constant, there are mathematics, physics, chemistry...... If you add up to 10 of them, you have to arrange them...... This is crazy. On what basis did we narrow it down?"

"Since we received the data, has there been a pattern in the signal? Is there any clue to this?"

"It's just repetition. However, if you bring the total length of the data, the repetition interval, and so on into the operation as constants, there is no result. I think maybe the Amis are right, and the clue is in the source itself. Or, we expect Cassini to share data. Either that, we will start our own exploration mission as soon as possible. At least for now, it has not been aggressive, and it may have been a peaceful exchange. ”

“……”

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

Now when the debate grows bigger, people realize that even with quantum supercomputing centers, it is difficult to decipher this information.

Just as in the era of the RSA algorithm, the top-level encryption algorithm is almost impossible to break, this encryption algorithm ...... Maybe just as hard.

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

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

That's right, things are going as planned.

He stretched and turned off the TV, and began to deal with what he was supposed to do today.

It's night on the other side, it's daytime, and the sun is shining.

……

In the room, Gu Song sat aside and didn't speak.

He seemed to be thinking.

He was really thinking, too.

It was an exam initiated by him, and he was watching the reactions of his compatriots.

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

In this long more than ten years, in the first stage, he has accumulated his strength and influence. At the same time, he also began to improve the industrial support capacity of this era in all aspects, and the technical level of making the whole project seem slightly more reasonable.

In the second phase, it began to build the Flint Space City.

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

He stood up, and then said, "Let's not talk about this for a while, we might as well reason logically." ”

The room fell silent and listened to him.

Gu Song walked to an electronic whiteboard and drew with an electronic pen.

"We're on Earth, it's in orbit around Titan. ”

With the outline of his electronic pen, the artificial intelligence system that supports it automatically recognizes its semantics. On the electronic whiteboard, he sketched a very accurate image of the Earth and Saturn.

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

"For now, it seems that everything is peaceful. So if we want to communicate with another alien civilization that may not understand the language at all, and we still use electromagnetic waves, why do we encrypt? The purpose of our encryption is certainly not to avoid being cracked, but to communicate. ”

"So, I don't think these ten constants are meant to make us crack this encrypted message. Is it possible that the process of deriving these ten constants is itself to communicate information. Or even that it's like a dictionary of a language, allowing us to understand their language through a certain process, in a certain form?"

"As we marked on the metal disc of Voyager 1, we indicated binary in it. So now, we at least know that on quantum algorithms, this signal can build a stable decryption model, is this also a kind of indication?"
