Chen Shen now feels like a primary school teacher, and as a hard-working gardener, he is handing over homework to the study committee at this time.

"Is that all, is there anything else?" Chen Shen watched Yang Xing take out the information.

"Nope." Yang Xing shook his head.

"Okay then, I'll tell you when I'm done."

Yang Xing clasped his hands together and was grateful: "It's troublesome, I'll invite you to the cafeteria another day to eat." ”

Chen Shen rolled his eyes, the cafeteria is free, can you kid please?

"Don't be a fool here, get out of here."

Yang Xing left with a smile, and Chen Shen turned his head and sat back at the table.

Putting aside the information he had just received, he turned his head and turned on the neural connection technology of the boxer.

He plans to make a prototype of the brain-controlled prosthetic system.

The boxer's neuronal connection technology can read most of the human nerve signals, with a wide reading range and high precision, and can accurately identify the corresponding instructions of different signals, so as to drive the mecha to act.

In the case of brain-controlled prosthetics, the recognition of neural signals does not need to be as large.

Now they're doing prosthetics of the hand, as long as they can recognize nerve signals from the movement of the hand.

For Chen Shen, this is a process of taking the essence of the original technology and removing its dross, only retaining the recognition of the active nerve signals of the hand, and removing all the other parts as dross.

Even more challenging is the problem of decoding algorithms.

He had to encrypt this simplified version of the neuronal connection technology with a decoding algorithm.

Otherwise, the outside world can obtain his decoding algorithm through the prosthetic, and then understand how he decodes nerve signals, and pick up a big bargain for nothing.

It is important to know that the neural signal decoding algorithm is different for each company, and a good set of decoding algorithm is an important factor in the speed and accuracy of neural signal recognition.

Even if the decoding algorithm he intends to use on the brain-controlled prosthetic is a castrated version, and when he gets a foreign brain-computer institution, their quotation starts at one billion, and the unit has to be a U.S. knife.

This algorithm is the core competitiveness of his brain-controlled prosthesis, so it must be protected.

However, his computer level is not bad, otherwise he would not be able to understand the various program systems of the mecha.

For encryption, he has long had his own encryption algorithm.

This is a set of AES encryption algorithm, 128-bit key encryption, if you want to crack the AES algorithm, with the computing efficiency of the Bitcoin network - 2.5644 * 10 per second to the 19th power, using a brute attack to crack, it will take about 210.4 billion years, and the electricity cost during this period is about equivalent to 100 million years of domestic GDP.

At the same time, he also used "masking" and other methods in this algorithm to prevent side-channel attacks, that is, to decipher the key through the running time, power, electromagnetic radiation and other methods of the cryptosystem.

Of course, this algorithm is not invincible, it can still be cracked using a quantum computer.

Well, if there were already quantum computers in the world that had already been put into practical use.

Chen Shen is already familiar with the neuronal connection technology, and this small change and the appropriate hardware are not a problem for him.

After a few days, while correcting the "homework" of Yang Xing and others, he gave his own opinions, and at the same time paid attention to the progress of data analysis of the plasma cannon.

At the same time, I am also keeping an eye on the progress of the liquefied neuronal connection, and now that the second two-person experiment has begun, if there are no accidents, the next one, the three-person experiment can be carried out.

Finally, it's time for him to streamline the neuronal connection technique, while also remotely guiding Ma Zhen's team to modify the prosthetic entity to fit his brain control system.

Despite the hectic daily life, the simplified version of the neuronal connection system was completed on time at the end of the week.

Chen Shen called He Xin and asked him to test it in the dormitory, confirming that this simplified version of the system could recognize the motor nerve signals in the hands.

His identity is different now, except for the boxer, he is no longer allowed to use mechas, let alone conduct any neuronal connection experiments.

Everyone was afraid that his brain would have problems due to the failure of the connection system.

With this system, Chen Shen went to the Brain-Controlled Prosthetics Research Center again.

Escorted by the same two people, he soon arrived at the town's research center.

I saw that there were a few more big words on the big iron door of the research center at this time: "Angular Brain Control Prosthetics Research Center"

It looks more like a small workshop.

Chen Shen couldn't cry or laugh.

Ma Zhen and the others all came out to greet them, everyone had thick dark circles on their eyes, and obviously they hadn't slept well in the past few days.

"Great god, long time no see."

Everyone greeted each other while yawning uncontrollably.

"Hello everyone." Chen Shen walked into the workshop and took a look.

I saw that the 3D printer inside was still working, printing joint parts.

At the same time, in the workshop, there was a middle-aged man who was a little nervous and his right arm was missing, and a shy teenager was standing next to him.

Ma Zhen walked over: "Let me introduce you." ”

"This is Uncle Wu, the volunteer we found, and next to him is his son Wu Xinying, both of whom are from the town next door."

"This is our... Leader Chen Shen, you may have heard of him on the Internet. Ma Zhen thought about it, but he didn't figure out what position Chen Shen had in the research center, anyway, he was the leader.

Uncle Wu's son's eyes lit up, "I've heard that you still have your mecha." ”

If he wasn't shy by nature, I'm afraid he would have pounced on him to ask for an autograph.

Chen Shen greeted them with a smile, turned his head and asked Ma Zhen, "Are the prosthetic limbs for the experiment ready?" ”

"Of course it's ready."

Ma Zhen led Chen Shen to a table, only to see a prosthetic leg of his right arm placed on it.

"This is the prosthetic limb that we have modified according to your requirements, the parts are all 3D printed, but the drive system has not been modified, and the execution time of the action remains the same."

When Ma Zhen said this, the people behind him unconsciously yawned.

For this prosthetic leg, they have only slept less than five hours a day for the past few days, which is really their best.

"It's good enough, after all, it's just an experiment, let's install the brain control system."

Chen Shen took out the brain control device he brought.

The device is similar to the sensing cap used to liquefy neurons for connection, except that it is a bit simplified and appears smaller.

There is also a signal conversion device that converts nerve signals into instructions that can be understood by a computer.

This device was made by him to Wang Qian, of course, it was angular money.

Cables are used to connect the sensing cap, the signal converter and the prosthesis itself.

"Let's test it first and see if the parts inside can work properly." Chen Shen said to Ma Zhen.
