Movie black technology

Chen Shen now feels that he is a teacher in elementary school. As a hardworking gardener, he is now handing over homework to the study committee.

"That's it, are there others?" Chen Shen watched Yang Xing take out a copy of the information.

"No more." Yang Xing shook his head.

"Well, I will tell you when I finish reading."

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

Chen Shen rolled his eyes. The cafeteria is free. Does it need you kid?

"Don't behave here, get out of here."

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

First, putting aside the information he had just received, he turned his head and turned on Boxer's neuron connection technology.

He plans to first make a prototype of the brain control system of the brain control prosthetic limb.

Boxer's neuron connection technology can read most of the human nerve signals, with a wide range of reading and high accuracy, and can accurately identify the instructions corresponding to different signals to drive the action of the mecha.

For brain-controlled prostheses, the recognition of neural signals does not require such a wide range.

Now they are making hand prostheses, as long as they can recognize the neural signals of hand movements.

For Chen Shen, this is a process of taking the essence and removing the dross based on the original technology, only retaining the recognition of the neural signals of the hand activity, and removing all other parts as dross.

The more challenging one is the problem of the decoding algorithm.

He must encrypt the decoding algorithm for this simplified version of neuron connection technology.

Otherwise, the outside world can obtain his decoding algorithm through prosthetic limbs, and then understand his way of decoding neural signals, which is a big bargain.

We must know that each neural signal decoding algorithm is different. A good 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 prosthesis is a castrated version, when he gets a foreign brain-computer organization, their quotation starts at one billion yuan, and the unit has to be a dollar.

This set of algorithms is the core competitiveness of angular brain-controlled prosthetics, so it must be protected.

However, his computer level is not bad, otherwise he can't understand the various program systems of the mecha.

For encryption, he has already 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, use the 19th power of 2.5644*10 per second with the computational efficiency of the Bitcoin network. It will take about 210.4 billion years to crack using brute force attacks. , The electricity bill spent during this period is approximately equivalent to 100 million years of domestic GDP.

At the same time, he also used "masking" and other methods in this set of algorithms to prevent side-channel attacks, that is, decrypting keys through the operation time, power, and electromagnetic radiation of the cryptographic system.

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

Well, if there are quantum computers that have been put into practical use in the world now.

Chen Shen has long been familiar with neuron connection technology. This small change plus hardware adaptation is not a problem for him.

After a few days, he corrected Yang Xing and the others' "homework" and gave his own opinions, while also paying attention to the progress of plasma cannon data analysis.

At the same time, we are still paying attention to the progress of the liquefaction neuron connection. Now the second two-person experiment has begun. If there is no accident, the three-person experiment can be performed next time.

Finally, it was the time he spent simplifying the neuron connection technology, and at the same time remotely instructing Ma Zhen’s team to modify the prosthetic entity to fit his brain control system.

Although daily life is very busy, the simplified version of the neuron connection system was completed on time on weekends.

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

He has a different identity now. With the exception of the boxer, he is no longer allowed to board mechas, let alone conduct any neuron connection experiments.

Everyone is afraid that his brain will have problems due to the failure of the connection system.

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

Still accompanied by the same two people, he soon arrived at the research center in the town.

I saw a few big words on the big iron gate of the research center at this time: "Angular Brain Control Prosthetic Research Center"

This looks more like a small workshop.

Chen Shen couldn't laugh or cry.

Ma Zhen and the others all came out to greet him. Everyone had thick dark circles on their eyes. Obviously, they hadn't slept well these days.

"Great God, long time no see."

Everyone yawned uncontrollably while greeting.

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

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

At the same time, in the workplace, there was a slightly nervous middle-aged man with a crippled right arm, and a shy teenager standing beside him.

Ma Zhen came over: "Let me introduce it."

"This is the volunteer Uncle Wu we found. Next to him is his son Wu Xinying. They are all from the town next door."

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

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

If he wasn't shy by nature, I'm afraid he would have rushed to sign.

Chen Shen smiled and greeted them, then turned to ask Ma Zhen, "Are the experimental prostheses ready?"

"Of course I'm ready."

Ma Zhen led Chen Shen to a table, and saw a right arm prosthetic placed on it.

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

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

For this prosthetic, they have only slept less than five hours a day in the past few days, so they really tried their best.

"It's good enough. After all, it's just a test product. Let's install the brain control system."

Chen Shen took out the brain control device he had brought.

This device is similar to the sensor cap used to connect liquefied neurons, but it is a bit simplified and looks smaller.

In addition, there is a signal conversion device that converts neural signals into instructions that the computer can understand.

He asked Wang Qian to make this device. Of course, it was expensive.

Connect the sensor cap, the signal conversion device, and the prosthesis itself with cables.

"Let's start the test first to see if the various components inside can work normally." Chen Shen said to Ma Zhen.
