I failed a course, and the system became my study supervisor.

Chapter 87 The research team does not welcome such people
Existing studies have divided neutrino mass production models into Type I and Type II based on nonstandard interactions (NIS).

Type I refers to the case where the loop that produces the neutrino mass contains at least one Standard Model particle, while the corresponding Type II is the case where there are no Standard Model particles at all.

One of the experiments caught Xu Ling's attention - T2K.

Based on experimental data, this is one of the better results among several studies.

But it has a problem that cannot be ignored.

Since the detector cannot distinguish between electron and photon signals, the neutral flow photon production process and the neutral flow pion production process will cause great interference to the detection signal of electron neutrinos, affecting the accurate measurement of NSI.

Photon signals can affect NIS, so can we use the influence of photon signals to get a glimpse of the whole picture?
An imaginative idea emerged from Xu Ling's mind.

Maybe it can help.

……

Two days later, in the laboratory.

"Nonsense! Is this how you approach scientific research?"

Zhang Zhongyao pointed at the noses of the two students in front of him and cursed, "I asked you to collect information on your own. Don't you have the ability to think independently?

The two people showed me exactly the same thing!

It's not just two copies of the information that are identical, but several copies are like this! Did you have an independent thought process? Do you have your own thoughts on this topic?

Too impetuous! "

Although Xu Ling knew that Zhang Zhongyao had become less easy-going after entering the project, he had never seen Zhang Zhongyao like this before.

He was furious and glared.

For a moment, the only sound in the entire laboratory was Zhang Zhongyao's scolding, and no one dared to breathe.

Observing silently from the side, Xu Ling discovered that the people Zhang Zhongyao scolded were all strangers who had just joined the research group at the beginning of this semester.

They are all undergraduates, and some are even freshmen who have just finished a semester.

"I know many of you just want to get some internship experience in the lab, but if you want to do it, you can't be so blatant!

How can you conduct further research when you have to give me a perfunctory reply when looking up a piece of information? You are all so young, yet you are so eager for quick success.

We don’t welcome such people in our laboratory!"

Zhang Zhongyao continued.

After hearing this, Xu Ling completely understood.

Is it normal to just muddle through scientific research experience in this era of internal competition? Some people muddle through and are considered highly skilled.

No one will say anything.

But at least you have to complete the tasks assigned by the teacher and make something of it.

You can't be worthless and cause trouble for the experimental group.

……

After a long time, Zhang Zhongyao's expression finally relaxed a little, and he walked out of the laboratory with his hands behind his back.

Everyone breathed a sigh of relief.

Unlike the others who were still frightened, Xu Ling went to get a glass of water and followed Zhang Zhongyao.

"Teacher Zhang, calm down."

Xu Ling said softly while handing over the water.

While drinking water, Zhang Zhongyao still felt a little uncomfortable: "Hey... these young people nowadays——"

Xu Ling did not respond and stood silently beside Zhang Zhongyao.

"Well, never mind them. Have you discovered anything from your previous research?"

Zhang Zhongyao stopped dwelling on this question and turned to ask Xu Ling.

Xu Ling did not hesitate and explained in detail his speculation about the photon signal.

"Yes, it's worth a try."

Zhang Zhongyao nodded, and his angry expression eased a lot.

Xu Ling is such a worry-free kid!

Zhang Zhongyao thought to himself.

As for those who had been scolded earlier, Zhang Zhongyao didn't say to kick them out of the lab directly, but Xu Ling felt that they should feel more at ease after this.

……

Although the project has begun, the establishment of the theoretical model and the preliminary design of the experiment have not yet been completed.

Everyone in the laboratory was busy.

However, on this day, Xu Ling took two hours off to go to the Youth Center Café on campus to accept Yu Wenkai's invitation. Yu Wenkai vowed that he had already completed the development plan for his company and hoped that Xu Ling could give him some advice.

Xu Ling had not planned to go because the lab was too busy, but he came anyway, remembering his promise.

"What are you drinking? Latte? Americano?"

Yu Wenkai asked enthusiastically.

"Have a matcha latte."

Xu Ling was familiar with the route.

Then, the two of them got down to business.

“This is the current plan.”

Yu Wenkai took out a document and placed it in front of Xu Ling.

Armour Cybersecurity Development Plan

armor?

The name is not bad.

Xu Ling thought as he turned the title page.

It took Xu Ling about fifteen minutes to roughly read the plan.

The content is very detailed, covering everything from basic company information, to product development direction, market research, financial forecasts, and so on.

But the core is still product development.

"Here we're focusing on side channel security. What is a side channel?"

Xu Ling asked doubtfully.

"Side channels refer to channels that can be exploited by attackers to indirectly obtain information, in addition to primary channels such as regular communication and data exchange."

Yu Wenkai spoke very professionally.

"What's an example?"

There was a Microsoft interview question from the 1990s that vividly illustrates what a side channel is. The question went like this:
There are three lights in the room, and the switches are outside the door. You need to control the switches to determine which switch corresponds to which light.

And you can only enter the room once."

After saying that, Yu Wenkai looked at Xu Ling with some anticipation.

It can only be entered once, but there are three switches.

Whether you turn both on or off, you can only determine the light in the different state.

……

and many more!

The nineties!

Xu Ling grasped the key point. At that time, all the lights were incandescent lamps, which would generate a lot of Joule heat when they glowed.

Turn on two lights first, wait for a while, and then turn off one of them.

When you enter the room again, the status of the three lights are different.

One is lit, and two are not.

But one of the lights that was not lit still had some warmth.

"You have to feel the temperature of the light bulb with your hand."

Xu Ling gave the answer.

"Haha, do you feel that? This is the use of the side channel. Obtaining information indirectly."

Yu Wenkai smiled slightly.

We understand side channels, but how do we use them for network security?
Xu Ling was still a little confused.

Yu Wenkai patiently explained this.

When cryptographic hardware devices (such as smart cards) perform encryption operations, the device's operation time, power consumption changes, electromagnetic radiation, etc. may become side channels.

This is also the reason why Yu Wenkai, as a student of the School of Physics, can combine his research with the field of cyberspace security.

"Okay, you've impressed me. I'm willing to keep my promise and invest half a million."

After thinking for a moment, Xu Ling expressed his opinion.

There is no need to look at financial planning and corporate management models, this research direction has already attracted Xu Ling.

Not only because it is novel enough, but also because it is of great significance.
