Movie black technology

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

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

No more. Yang Xing shook his head.

Alright then, I'll let you know when I'm done.

Yang Xing clasped his hands together, grateful: Please, God, I will invite you to the cafeteria for dinner some other day.

Chen Shen rolled his eyes, the cafeteria is free, do you need it?

Don't be a good boy here, get out of here.

Yang Xing left with a smile, 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 neuron connection technology of Boxer.

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

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

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

Now they are making prosthetics for the hand, as long as they can recognize the neural signals of hand movement.

For Chen Shen, this is a process of extracting the essence and discarding the dross on the basis of the original technology. Only the recognition of hand activity nerve signals is retained, and all other parts are discarded as dross.

What is more challenging is the problem on the decoding algorithm.

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

Otherwise, the outside world can obtain his decoding algorithm through the prosthesis, and then understand his decoding method of nerve signals, and get a big deal for nothing.

We must know that the neural signal decoding algorithm of each company is different. A good set of decoding algorithms 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, if he gets it from a foreign brain-computer institution, their quotation will start at one billion, and the unit must be US dollars.

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

However, his computer skills are not bad, otherwise he would not be able to understand the various programming systems of the mecha.

For encryption, he already had his own encryption algorithm.

This is a set of AES encryption algorithm with 128-bit key encryption. If you want to crack the AES algorithm, it will take about 210.4 billion years to crack it with the calculation efficiency of the Bitcoin network - 2.5644*10 to the 19th power per second. , The electricity bill spent during this period is roughly equivalent to the domestic GDP of 100 million years.

At the same time, he also used methods such as masking 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 cryptographic system.

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

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, and this small change plus hardware adaptation is not a problem for him.

After a few days, while correcting the homework of Yang Xing and others and giving his own opinions, he also kept an eye on the progress of the data analysis of the plasma cannon.

At the same time, I am still paying attention to the progress of the liquefied neuron connection. Now the second two-person experiment has begun. If there is no accident, the next three-person experiment will be possible.

In the end, it was time for him to simplify the neuron connection technology, and at the same time remotely guide Ma Zhen's team to modify the prosthetic body to adapt to 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, and confirmed that the simplified version of the system could recognize the motor nerve signals of the hands.

His identity is different now, except for the boxer number, he is no longer allowed to be on the mecha, 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-controlled prosthetics research center again.

Still escorted by the same two people, he soon arrived at the research center of the town.

I saw a few big characters on the big iron gate of the research center at this time: Angular Brain-Controlled Prosthetics Research Center

This looks more like a small workshop.

Chen Shen didn't know whether to 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.

God, long time no see.

Everyone greeted each other and yawned uncontrollably.

Hi 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 slightly nervous middle-aged man with a mutilated right arm, and a shy teenager in his teens was standing beside him.

Ma Zhen came over: Let me introduce.

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

This is our...leader Chen Shen. You may have heard of him on the Internet. Ma Zhen thought for a while, but he couldn't figure out what position Chen Shen held in the research center. He should be the leader anyway.

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

If it wasn't for his natural shyness, I'm afraid he would have rushed forward to ask for his autograph.

Chen Shen greeted them with a smile, then turned to Ma Zhen and asked, Is the experimental prosthesis ready?

Of course I'm ready.

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

This is the prosthetic 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 unchanged.

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

For this prosthetic limb, they only slept for less than five hours a day in the past few days, and they really did their best.

It's good enough, after all, it's just a test product now, let's install the brain control system.

Chen Shen took out the brain control device he brought.

This device is similar to the sensing cap used in the connection of liquefied neurons, but it is simplified and looks smaller.

In addition, there is a signal conversion device, which is responsible for converting neural signals into instructions that the computer can understand.

He asked Wang Qian to make this device. Of course, he spent a lot of money.

Cables connect the sensing cap, the signal conversion device, and the prosthesis itself.

First turn it on and test it to see if the various components inside can operate normally. Chen Shen said to Ma Zhen.
