Storms always come suddenly.

Under the joint operation of the Ministry of Public Security and the General Staff Headquarters, a number of spy organizations lurking in China were uprooted, a total of 67 intelligence documents that had not yet been sent were intercepted, and more than 200 pieces of leaked information were traced.

According to the list of confessions made by the people involved in the case and the clues intercepted by deciphering the espionage documents, almost all the criminals from the high-level to the grass-roots level were arrested and brought to justice, and the officials involved were also arrested one after another.

Unlike other crimes, treason is always the most sensitive high-voltage line, and there is no room for compromise in the face of this red line.

At the same time, the CIA headquarters, which is far away on the other side of the Pacific Ocean, was also passively involved in this thunderous operation that swept the entire country, causing a stir.

The timing of the arrest of intelligence agents in China in other countries and the speed with which they were launched were beyond the expectations of CIA intelligence experts and high-level decision-makers.

It's not that they haven't considered the possibility of leaks, and it's not that they haven't prepared for the crisis, but everything seems to be useless at this moment.

They don't know when it started, it was already around their necks, and even when it started to tighten, they didn't feel anything unusual at all.

They can't even be sure now whether the information they have received during this period of time was sent offline or deliberately shown to them by the General Staff of Huaguo.

In any case, this fiasco was already doomed to them from the beginning.

The losses caused by this are almost more than the CIA's overseas activities in the past decade combined, and even comparable to the Waterloo they suffered in the Bay of Pigs.

And that's not even the deadliest.

The most fatal thing is that they even know that now they don't know where such a big basket came out, and they actually directly put the entire intelligence network that they spent more than ten years deploying in China.

In short, no matter what, it has happened, and someone has to be held accountable for it.

It is said that on the night of the incident, the president was furious in the White House palace, angrily scolded the director of the CIA, and threw the investigation and evidence collection directly to their old rival FBI.

In the hands of the FBI, their lives were not so good.

In addition to the urgent withdrawal of intelligence agents deployed in the Asia-Pacific region who have not yet been caught, a purge is also unfolding within the CIA.

First, the director of the C.I.A. resigned, and then more than two dozen high-ranking officials were suspended from their posts and placed in the custody of the F.B.I. for investigation.

However, no one would have thought that it was not because of any traitor at all.

The person who exposed the information and whereabouts of their intelligence officers was not an insider at all, just a small box the size of a palm.

In front of it, there are no secrets at all.

Not to mention just a few spies......

……

Just when North America's intelligence system in the Asia-Pacific region was almost paralyzed, the real "mastermind" behind this series of chain reactions, Academician Lu, still had no idea at the moment.

He didn't know that his invention had done such a terrible thing.

It was Chang'an Avenue who wrote the letter to take the small box, and it was clearly said that it would be taken for research, and at the same time help him solve the matter of secret patents. However, Lu Zhou probably wouldn't have imagined that the front foot of the small toy he made had just been sent to Chang'an Avenue, and the back foot was borrowed by the State Security Bureau, which was engaged in counter-espionage work......

However, for him as a scholar, there is really no need to know so much.

Knowing more about some things is a burden, and not telling him is not for the sake of protection.

For at least 50 years, the story behind the operation will be sealed in the archives as a top-secret document, and it is impossible for anyone other than the person who gave the order and the person who carried it out to know the truth behind the thunderous operation.

After all, with the CIA's narrow mind and grudge-holding urine, if he knew who did it, he was afraid that he would have to have the mind of driving the plane to Lu Zhou.

But then again, even without these things, some people may not want Lu Zhou to live......

In the field of security, quantum computers have shown their terrifying power.

Although not many people know that it is caused by this shocking change that may change the strategic balance of the entire Asia-Pacific region, because the central government has been blowing the wind some time ago, the major relevant research units are still actively or passively studying the encryption algorithm on the restraint of quantum computer technology.

Institute of Information Engineering, Chinese Academy of Sciences.

As the top research institute in the field of information security in China, a group of bulls who can not easily guess their identity as strong people just by looking at the amount of hair are sitting at the conference table and discussing.

Some time ago they received an order from Chang'an Avenue.

According to reliable sources, the Pentagon is studying the application of quantum computer technology to intelligence gathering, and Shangjing hopes that they can develop an encryption algorithm to deal with cyber attacks launched by quantum computers with more than 1,000 qubits.

In fact, this requirement sounds strange, because the highest quantum computer technology is now only 100 qubits, and it is a bit unreasonable to consider more than 1,000 qubits.

But in any case, judging from the importance of the central government and the funds allocated, this task does not seem like a joke. Almost half of the biggest names in the field of cryptography were gathered in this conference room of less than 50 square meters, and everyone signed a confidentiality agreement before entering......

"Today is the fifth meeting," Academician Xue Jinhui continued with a serious expression, glancing around at the conference table, "I hope everyone can brainstorm and put forward some constructive suggestions." ”

This academician Xue Jinhui has a lot of background, not only serving as the deputy director of the Institute of Information Engineering of the Chinese Academy of Sciences, but also participating in the development of the Twin Field Quantum Key Distribution (QKD) protocol.

This QKD protocol is also the first quantum encryption algorithm independently developed by Huaguo's scientific research team. It is for this reason that he was selected as the academic leader of the entire project.

There was a lot of talk in the room.

The big bulls in the cryptography industry here looked at each other, exchanging headaches and helplessness in their hearts with their eyes.

As Academician Xue said, this is the fifth meeting, but they really don't know what else to communicate other than those clichés.

Cyberattacks launched by 1000-qubit quantum computers......

Being targeted by this "alien-level" power, it's better to simply lie down. The technical generation gap is no longer a problem that can be solved by a few meetings.

In addition to giving up resistance, the only way they can think of is the inefficient means of communication such as "one secret at a time", or the era of "correspondence" to fight this method of cracking in the true sense.

"The efficiency of the LWE scheme is too low, the Soliloquy scheme is not safe enough, and the quantum communication conditions are too harsh, so point-to-point communication is no problem, and distances of more than 100 kilometers can be directly excluded, unless we can equip everyone with the Micius satellite key...... Hey, this leader really gave us a problem. ”

Shaking the cigarette clipped to his finger, an old man with gray hair took a puff, the wrinkles on his face huddled together.

Another middle-aged man with glasses sitting next to him showed a hint of displeasure on his face, as if he couldn't stand the smell of smoke, but he didn't say anything, just coughed lightly and said.

"It would be nice if we could get Academician Lu into our project team. Cryptography is still a mathematician's specialty. ”

As soon as this sentence fell, many people subconsciously turned their attention to Academician Wang Shicheng who was sitting at the corner of the table.

Academician Wang Shicheng, who was watched by so many people and almost began to doze off, looked confused, opened his eyes and said.

"What are you watching me do?"

An academician sitting next to him coughed and said.

"Isn't that counting on your Yan University Mathematics Center to come up with ideas?"

"Don't look for me," Wang Shicheng waved his hand, "This thing is no longer in the category of mathematics, you should go and study physics." ”

Hearing this big figure in the Chinese mathematics community say this, many people showed a wry smile on their faces. Especially Academician Xue, his smile was bitter and a little embarrassed.

A young professor who had been sitting next to him and had not spoken, suddenly spoke.

"Speaking of which, Academician Lu is mainly in charge of the work of the IMCRC now, right? It seems that something is being studied...... Boat particles? ”

The professor sitting across from him nodded.

"Z particles, I've heard of them. I've read that paper several times, and the properties of the Z-particle are a bit interesting, they exist for a while and then they don't. When it doesn't exist, you can't see it on other axes of the high-dimensional space, and when it exists, you only have a tail exposed...... Eh, you say, is it possible to use this Z-particle for communication? ”

"I don't understand ...... But when you say this, it seems to be really interesting, why don't we consult Academician Xialu? ”

The topic has developed so far, and it has completely digressed.

With a heavy cough, interrupting the conference table that began to become lively, Academician Xue looked at the scholars who had stopped talking and spoke.

"Okay, don't think of Academician Lu at every turn, the central government must trust our ability to hand over this task to us. As for Academician Lu, he has his own affairs to deal with, and we can't rely on him to do everything. ”

After a pause, he continued, "Also, what we're talking about is not the means of communication, but how to add a lock to our information, don't go off-topic!" ”

The crooked topic was broken back by this academician Xue in a few words.

Embarrassingly, however, when the conversation got back on track, the entire room fell back into silence, and there was no one to speak.

At this moment, there was a sudden knock on the door, breaking the embarrassment in the conference room.

As if saved, Academician Xue hurriedly spoke.

"Please come in."

The door opened.

I saw his young assistant, holding a stack of documents in his hand, hurriedly walking in.

Looking at the documents sent to him, Academician Xue was slightly stunned for a moment, and subconsciously asked.

"What is this?"

"There's the latest news from the central side......"

Looking at the inquiring expression on Academician Xue's face, the young assistant swallowed his saliva and said with a somewhat embarrassed expression, "The project of quantum encryption algorithms ...... was canceled. ”

A previously silent conference room.

It was lively for a moment......
