West Coast, Changqing State.

As the General Administration of Information Security of Yuxia began to fully close the network, the CIA in District 1 gradually realized that its informants in District 9 seemed to be losing contact.

But they can't be entirely sure.

Because many times they have key informants in other countries, and they don't keep in touch with them all the time, every day.

In addition to posting tasks, they generally don't reach out to key informants.

Because this increases the risk of exposure to key informants.

But their monitoring and understanding of key informants doesn't stop.

No one knows better than them what these informants will do, and even to some extent, they will know better than the informants themselves.

It's like having a university professor in White City, who makes a video call to his lover every day, in addition to providing information.

But in the last few days, this action has disappeared, and although his intelligence has not been interrupted, he has not contacted this lover again.

This is a very small thing, maybe it is nothing in the eyes of normal people, after all, sometimes it is normal to forget to call when you are busy, and it may also be that people are tired together and don't need video.

But in the eyes of the CIA's intelligence service, this was enough to cause alarm.

.......

In the midst of this situation, an emergency meeting is being held in the CIA's Silver Shield building.

"Guys, I think there's something wrong with the informants we've planted in District 9, or rather, they're in trouble."

Fifty-six years old, gray-haired, glasses, and a pipe in his mouth, David Peter, the head of the Intelligence Analysis Division, banged on the table and said in a deep voice.

"Why? Isn't our intelligence system still functioning? Every day news comes back from that country. ”

The Chief of the Intelligence Management Division asked with a frown.

"Yes, the intelligence system is functioning normally, and news is coming back from that country every day, but some of our key informants have been operating very differently lately."

"Look at this, everybody."

David Peter knocked on the table, and a projection appeared in the conference room.

"From the information and data we have gathered, there is something unusual about the recent activities of our key informants."

"This is one of our informants in White City, and he used to video call his lover every day, but that has stopped in recent days."

"This is an informant from Bright Moon City, one of the leaders of the women's boxing organization we have cultivated, and he forwards and sends some news messages every day on an app called 'Bibirch' in that country, and similarly, his account has stopped updating in the past few days."

"And the informant ...... in Sebei"

"There are a lot of things like this, and if it's one or two cases, it might still be a coincidence, but now, I seriously suspect that something is wrong with our intelligence system."

David Peter said in a deep voice that he is quite sensitive to information and can analyze a lot of useful information from some small details.

Clues that seem insignificant in his eyes are the path to the final answer.

"But the intelligence of these informants has not been interrupted these days, and the information was transmitted back just three hours ago."

The head of the Intelligence Management Division frowned and flipped through the computer in his hand.

"That's where the most suspicious thing goes."

David Peter said in a deep voice: "I suspect that they have all been exposed or even caught, and now it may not be me who contacts us and provides us with information, but people from that country, and our 'God Encryption' system may have been completely cracked by them." ”

Hearing this, the entire conference room was in an uproar.

"Impossible! That's impossible! ”

"God encryption is an encryption method designed by the top mathematics professors of the Ivy League, using the world's most cutting-edge logic and function knowledge, in that backward country, do they have real mathematicians?"

"Dave, you are underestimating our opponents, the country on the other side of the river is growing rapidly, and now it is the second largest economy in the world."

"So what, if our country also has a population of more than a billion people, it will develop better."

"Actually, I'm more curious about how they quickly locate our informant, it's normal for our encryption algorithm to be cracked, and if the other party relies on mathematicians to decrypt it, it can indeed be done, but accurate and fast locating, it's almost impossible."

"The encrypted messages we send out every day are mixed with a lot of useless information, and it takes a long time for humans to unravel them."

"Unless they have accurately found every mathematical law behind the encryption algorithm and established a mathematical model, it will never be possible for human beings to keep up with us."

"And these are just coincidences?"

“......”

In the conference room, CIA Director John Brennan, who had been silent, knocked on the table, interrupted the conversation, and looked at Will Wadsworth, a mathematician who had been specially invited.

Will Worthworth, a tenured professor emeritus at H Fo University and a Fields Medal winner, is highly accomplished in mathematics and cryptography, and he led the God Encryption Project.

"Professor Will, what are the chances that our encryption algorithm will be fully cracked?"

Will Worthworth pondered for a moment and said, "There is a perfect encryption algorithm in mathematics, but in reality we can't write it." ”

"However, according to my estimates, even if the ninth district can fully unlock the God encryption, it will take at least two or three years or more."

"It's only been a few months now, and the other party has broken our God Encryption, which is indeed a bit beyond my expectations, and this possibility is less than one in 10,000 in my opinion."

"You know, it took us more than five months to conceive and design this encryption system."

"If it weren't for the performance of the decryption equipment in the hands of the spy, we could even insert a real encrypted message into tens of thousands or even hundreds of thousands of fake messages."

"In this way, this encryption system is the real 'God encryption', and God can't unravel it."

John Brennan rubbed his temples with some headaches: "It seems that we have to be prepared to reduce the losses, let those key informants who can come back come back with the information first." ”

Many of the informants they have planted in the 9th Sector have used this God encryption system for communication and information transmission over the past few months.

If the other party really mastered the means of decipherment, then the loss this time was really too great.

Even the informants who have been inserted and developed in the past ten years will be uprooted.

At that time, their control of information in the ninth district will be blank, reduced to the lowest level ever,

If they don't even know what the other person wants to do, how can they limit the other person's development?

This is an impractical question.

If that were to happen, he would be a sinner in the First District.
