State Administration for National Defense.
Director's office.
An old man with a white beard angrily pushed open the office door and walked in from outside.
"Old Li! I want to know what's going on! "
This movement didn't scare Director Li, but his secretary was startled.
Other people wouldn't dare to talk to the director of the State Administration for National Defense like this, but Academician Xue was obviously not an ordinary person.
Not to mention the State Administration for National Defense, even the head of the Ministry of Industry and Information Technology, the superior department of the State Administration for National Defense, had to treat this old man with great respect.
Director Li saw Academician Xue at the door. He seemed to have guessed why Academician Xue was here, so he quickly put down his pen and smiled.
"Why are you here? Have a seat … Xiao Zhou, pour Academician Xue a cup of tea, then help me send this document to the materials room. Make 50 copies and send them to Director Liu. "
"Okay."
The secretary, Xiao Zhou, smiled and poured a cup of hot tea for Academician Xue. He then picked up the documents on the table and quickly walked out of the office, closing the door behind him.
"Hmph!" Academician Xue glanced at the closed door and waited for the footsteps to disappear. He picked up the teacup on the table and drank half of it. He then slammed the cup on the table and said angrily, "You're asking me why I'm here? If I wasn't pissed off by you guys, why else would I be here? "
Director Li didn't have a chance to speak. Academician Xue's mouth was like an open machine gun.
"You guys are the ones who want to do quantum encryption! Now you're the ones who want to stop! Half of the Chinese cryptography community is in Beijing, and our work has only just begun. You're going to stop now? Are you trying to fool us? "
Director Li heard Academician Xue's complaints and felt a little awkward. Speaking of which, this matter was indeed his fault, but he couldn't be blamed entirely.
"Um … It's a bit complicated."
"Complicated? Didn't I remind you guys? Even the most advanced quantum computers don't have 100 qubits. Treating a 1,000-qubit quantum computer as an imaginary enemy is insane! "
In Academician Xue's eyes, this kind of inexplicable research project was a stupid decision. He had always hated this kind of administrative interference in scientific research. Not only was it a waste of resources, but it was also treating research as child's play!
Director Li coughed and said.
"The reason for canceling this project is not because of this, and it's not completely canceled. It's just a strategic adjustment …"
Academician Xue's face was filled with anger. "Then why?!"
"… Because someone has already solved this problem."
The office instantly fell silent.
The moment Academician Xue heard this, he was stunned. It took him a while to come back to his senses.
"… It's settled? What problem has been solved? "
"Other than that quantum encryption algorithm, what else could it be —"
"Impossible!"
Academician Xue's eyes widened, and his face was full of disbelief. He thought Director Li was fooling him, and he became even angrier as he said, "Half of the big names in the cryptography world are here, and you're telling me the problem is solved? Do you know what you're saying? "
They hadn't made any substantial progress in their research for a whole week, and now someone was telling them that the problem had been solved? Someone had completed an algorithm that none of them could even think of in a place he didn't know about?
He had never heard of anything more absurd than this!
Director Li sighed and said, "You're here too … I was planning to discuss this matter with you."
As he spoke, he opened the drawer and took out a disc stored in a special container.
Academician Xue looked at the disk and frowned. Without waiting for him to ask, Director Li continued.
"The quantum encryption algorithm I mentioned is in here … Of course, it can only be placed in my office now. It can't go out of the door next to you. However, I can demonstrate it to you on my computer. "
Academician Xue had a look of disapproval on his face as he snorted.
"I'm not that easy to fool."
Director Li smiled and said, "I know, but after all, we're just laymen. We have to rely on the opinions of experts like you … That's why I wanted you to see if this thing can block the attack of a 1000-qubit quantum computer …"
As he spoke, he had already inserted the CD into his laptop.
Director Li turned the computer around and faced Academician Xue.
Academician Xue drank the cup of tea on the table and stood up from the sofa. He walked to the side of Director Li's desk and took a chair to sit down.
Academician Xue clicked on the screen and opened the file in the driver. He then looked at the algorithm file line by line.
To be honest, it was impossible to develop a stronger and brand-new encryption algorithm based on algorithmic logic that was completely different from the BB84 protocol in such a short period of time.
Any research was based on scholars in this field, and the top scholars in this field that he knew were all in his research group.
These people couldn't think of any good ideas, so he didn't think anyone else could.
Unless they hired "outside help".
However, this was a matter of national security. The possibility of outsourcing the encryption algorithm to a foreign research team was almost zero.
Academician Xue had a nonchalant expression on his face as he quickly scanned through the dozens of lines.
However, as his gaze continued to move downwards and the mouse wheel continued to roll, the expression on his face gradually changed.
This time, the change was very subtle, but it was obvious in Director Li's eyes.
Finally, this stubborn old man couldn't help but ask.
"This thing … Who made it?"
"I really can't tell you that." Director Li coughed and said, "It's top secret, please understand."
The office went silent for a while.
Academician Xue stared at the computer screen intently. He suddenly looked away from the screen and looked straight at Director Li. He spoke in a slightly hoarse voice.
He spoke in a slightly hoarse voice, "Could it be Academician Lu?"
That's the only possibility …
Director Li didn't speak, and the expression on his face didn't change.
But sometimes, not having an expression was equivalent to an answer.
Academician Xue turned his head. He had a shocked expression on his face as he looked at the rest of the algorithm in a daze.
As if he had seen some shocking miracle, he murmured to himself as if he was sleep-talking.
"So it's him … No wonder."
No wonder the project was canceled.
With this kind of encryption algorithm, they really had nothing to do with it.
However, thinking about it made him feel sad. More than 20 of their heads combined couldn't even compare to one of his.
His shocked expression couldn't help but have a hint of bitterness.
In the past, he didn't care about the emotions of his old friends. Now, he finally understood why working with Academician Lu was a frustrating thing.
This wasn't just a sense of frustration; it made people doubt their lives and feel despair.
Thinking about it this way, not telling them the reason for the cancellation of the project was a form of protection …
Seeing how Academician Xue didn't respond for a long time, Director Li was a little anxious.
"Don't just be emotional … Tell me, what do you think of this encryption algorithm?"
After a while, Academician Xue spat out a word.
"Very strong."
"What does' very strong 'mean?"
"It means, forget about 1,000 qubits …"
Academician Xue gulped and said with a trembling voice, "I'm afraid 2,000 qubits is not a problem at all …"
