The only way to be absolutely safe is to start with the mechanics. Pen ~ fun ~ pavilion www.biquge.info

This may sound like a contradiction, but through the network connection, it is naturally related to the software becoming aspect, how can it be related to the mechanics?

If you don't understand, you can ask, and Ye Qing sent an email to the past.

"Data encryption is actually a process in which the plaintext is converted into meaningless ciphertext after the encryption function, and the receiver uses the key to decrypt it into plaintext. ”

"Among them, the encryption method written by the software. It is possible that the encrypted content can be brute-forced, or even because of a certain vulnerability, the encrypted content can be obtained without brute force. ”

"Mechanical encryption, from the earliest Enigma cipher machine to the current electronic cipher, is a kind of mechanical encryption. ”

"Today's asymmetric encryption methods, through dynamic digital certificates and private keys that never need to pass data, can avoid being brute-force cracked by computers using frequency analysis. ”

The private key kept in the user's hand is usually an independent dynamic password generated by the vibration of the quartz crystal according to the principle of time synchronization. ”

"As long as the key is not lost, criminals have lost the possibility of large-scale cracking of this extremely cheap mass production key. ”

"If you use more advanced industrial technology, you can create multiple encryption keys, or independent keys. The password can only be obtained by stealing the ontology of the key through physical means. ”

"In code-breaking confrontations, the weakest link is always the human being. Use supercomputers that are only in the hands of a few large countries to carry out brute force attacks. Far less effective than cultivating a thief, or being a spy. ”

The explanation of the True Eye made Ye Qing basically understand the principle of how to ensure communication security.

It's like today's bank fraud calls, where scammers are almost pretending to be immortals, and they have worked hard to get a dynamic password.

The SMS dynamic password may be intercepted from the base station.

The electronic port token is usually only the size of a USB flash drive. Because there is no need to pass through the data transmission at both ends, it is impossible to transmit data, and the condition of physical isolation is achieved.

Theoretically, as long as the password is generated by the algorithm, it is possible to exhaust it. However, the dynamic password changes once a minute, so that the computer cannot calculate the correct password in a limited time.

If each key is made with multiple encryption and independent craftsmanship, it can be more secure to avoid cracking.

Unless......

Like many spy war films, the encryption system developed at a huge cost turned out to be a traitor who sold the technology for tens of thousands of yuan, or gave it to the enemy for nothing.

This kind of thing may happen in other companies, but here in Ye Qing, it will never be.

Because it's not people who make these keys, it's monsters.

By physically connecting the key to the robot's electrical signal controller, the key can be lost and the robot cannot be started and operated.

It is enough to use this encryption method in the civilian field, and in the military field, once there is a war, it is a confrontation without any bottom line. Just using full-band blocking, or magnetic storm suppression, can make the robot lie on its stomach.

At the end of work, Ye Qing returned to the factory with the information sorted out.

At present, it is more reasonable to launch two kinds of robots, one for household use and one for industrial use.

When he arrived at the factory office, Ye Qing called Yan Zhaoge, the boss of Vision Technology Co., Ltd., to discuss the purchase of VR cameras and orders for VR displays.

The battery also has to be re-purchased, and at the same time, according to the test report of the employees, the kind of full-cover alloy operating suit, which is a little cumbersome to wear, is better to be more concise.

There is also the adjustment of the robot's strength, as well as the key production plan, and the ......

Anyway, there are a lot of them, and Ye Qing has to find a way to dig out the True Eye.

If you can invite him to join, then in the field of network security communication, Ye Qing will definitely be like a tiger.

The improvement plans were listed one by one, and Ye Qing was handed over to the master of ingenuity to be responsible for the production of the second-generation robot prototype.

Then Ye Qing began to call a well-known domestic precision sensor manufacturer to ask about the price of magnetic induction chips and supporting digital processing systems.

The robot is just one of the products that Ye Qing envisioned, and for the robot, Ye Qing was actually not very sure in his heart when he tested it.

Because it doesn't have the slightest intelligent program, and the price will be very expensive, the families who are willing to consume it, one out of a thousand, is already considered a huge success.

But robots are about whether Monster Heavy Industries can subvert the traditional industrial manufacturing market in the future. Like Boeing and Airbus, it is an important prerequisite for becoming an absolute hegemon in a cutting-edge field.

The sooner this is put on the market, the better, and there is no doubt that the best opportunity is when the movie is released.

The second product is different.

Ye Qing has absolute confidence that after the launch of this product, it will be able to sweep the world like Apple's mobile phone.

Even more tricky than an iPhone!

No~ Ye Qing is confident that the sales of this product, especially among female users, will definitely be better than Apple's mobile phone.

And its price will be more close to the people, so that it can truly enter the lives of the people.

Ye Qing's first phone call was to [Xinchuang Future] Co., Ltd. in Dongguang City. The phone rang twice and was answered by a female operator with a slight Cantonese accent.

"Can your company produce magnetic induction chips with magnetic field saturation induction between 0.8t and 1.5t, and supporting digital processing systems with an accuracy of 1.5t?"

"The sensor head should be the permalloy kind. ”

The operator hesitated for more than ten seconds before he said please... Please wait a minute, I will consult our technician.

Two minutes later, the phone was transferred to a man with a deep voice.

"I'm Liu Dongyu, the president of Xinchuang Future, who are you?"

"Ye Qing, the president of Giant Beast Heavy Industries!"

"Giant ...... Giant Beast Heavy Industry?" Liu Dongyu was so surprised that he spoke in a knot, obviously this person had heard of the name of Giant Beast Heavy Industry.

"I also use your company's mechanic chair. After being surprised, Liu Dongyu looked very excited: "Just now the technician called me and said that someone wanted to purchase an induction head made of permalloy, and I wondered who needed this kind of thing." ”

"It turned out to be Mr. Ye, Mr. Ye has good eyesight. Our core creation of the future, the technology of manufacturing magnetic induction system is second to none in China. ”

"We can produce the products you want, I don't know how much Mr. Ye wants to purchase?"

"The minimum order is 100 sets, and for every 1,000 sets more, the price will be reduced by 1 percent, and the cap will be 20 percent. Liu Dongyu's eyebrows were squeezed together, he knew a little bit about Monster Heavy Industries, the products produced by this company were simply profitable, if he could get a cooperative relationship with him, it would not be developed in the future?

"In the case of ensuring that the parameters are absolutely up to standard, how much is a set?"

"Two thousand sets, Mr. Ye, how much do you order?"

"I want two sets of this magnetic induction system to apply the production line, and the supporting production technology. (To be continued.) )
