Chapter 478： Ok (below)

Things are not in the conference room, but in a warehouse in the base. When General Liu arrived with Guo Tailai and Zhao Wei, he saw a large iron cage in the warehouse. Indeed

To be honest, it is not an iron cage, but two, one of which is propped up to a certain height and wrapped in an iron cage outside. The iron cage is woven from iron wire, the mesh is very thin, and the inner and outer layers are the same fine. Not only that, Guo Tailai also noticed that the walls around the warehouse are actually metal, as well as the ground and ceiling.

Iron cages or metal warehouses are all designed to ensure that electromagnetic waves are not emitted and received. The principle of electrostatic shielding, high school physics and electrical knowledge, Guo Tailai understands.

It is also because of the reason for being so cautious, so Guo Tailai also understands the importance of the things brought over today. I haven't seen anything yet, and I haven't started to work yet. Guo Tailai has already taken it seriously. positive

There is a very solid wooden table in the middle, and there is an explosion-proof barrel that Guo Tailai knows next to the table. This is just in case, once there is a danger of explosion inside, throw things into the explosion-proof bucket in time, or have a chance not to be hurt. Sure enough, it is a big enemy! One

A lieutenant colonel, with a metal box, walked into the innermost cage. When he dropped the box, Guo Tailai discovered that his hands and boxes were tied together.

General Liu and the lieutenant colonel made a formal handover and signed a document from a lieutenant colonel. After General Liu signed the word, he and the lieutenant colonel walked out of the iron cage, and the first floor, the door of the first floor, ensured that there would be no electromagnetic signal leakage. "

Fat man, this thing is very important. If you are not sure, you would rather not do it, nor can you ruin the things inside, understand? Outside the iron cage, General Liu glared at Guo Tailai who was about to enter the cage.

I know. Guo Tailai nodded. "I don't know if I won't move. Don't worry, I know how important." ”

General Liu Zhao and the lieutenant colonel watched outside the cage. Guo Tailai walked in with a small toolbox. Just like the program that comes out, enter the door that closes the first floor and open the door inside.

The metal box was placed on the wooden table, the lock had been removed, and Guo Tailai opened the metal box easily. Unsurprisingly, there was a smaller metal box inside. Opening the second floor, Guo Tailai saw a device that was a little thicker than the Oxford Dictionary.

It should be an electronic device. It obviously has a data interface and a power interface. But in addition to this interface, it is a square metal box with obvious screw threads or something, but it does not see fresh. Twist the traces. "

Have you tried to read the data directly? Guo Tailai asked the data and power interface curiously.

"There is a protection device inside the hard disk, hardware verification, once the access system is wrong, it will start data self-destruction." General Liu replied quickly outside: "So I dare not give power, the built-in battery is enough in this state." After a few years of use, we can't wait for such a long time. And as long as a power supply will be charged and started, it is very troublesome." Very

Obviously, there is a special hard drive inside, I don't know what data is saved. hard

The box was not moved in the box. Guo Tailai cautiously asked: "Is there a problem with direct handling?"

"There is no problem with normal movement." General Liu replied again: "But before the internal self-destruction device fails, it cannot be easily opened. Otherwise, everything will be gone."

understood! Guo Tailai nodded, put the hard disk box in his hands on the table, and then moved the box out to make room.

The hard disk can't be read by power, you can only find a way to open it, then directly open the hard disk, physically read the data on the disk and then analyze it. This is the most secure method. Guo

When Tailai was talking, a large number of nanobots had already drilled through the gaps in the data interface. General Liu reminded him that he could not read it at random. Guo Tailai did not take risks, but first looked at the structure of the self-destructing device inside. One

While checking, a group of nano-robots easily penetrated into the hard disk. Can not directly read through the data interface, this can not help Guo Tailai, he can directly read the magnetic media, that is, directly give him a hard disk, Guo Tailai can read the above without any magnetic head equipment data. Anyway, first back up one, just in case. hard

The disk capacity is not large, that is, 2g of space. Numerous nano-robots are swarmed up, and it takes less than ten seconds to store all the data on several parallel parallel disks. What is the content? Guo Tailai does not care, I will talk about it later.

"Liu Shu, do you have such a multi-layer metal screen, is this thing able to send out electronic signals?" Guo Tailai looked at him while asking for General Liu outside. "

Yes. "This time General Liu did not answer, but the lieutenant colonel replied: "We have detected that this hard disk will send an electronic signal without rules. If it is intercepted, you may get the location of the hard drive. But what we are more afraid of is that the other party sends a self-destruct signal, and once it receives this signal, it will probably start self-destruction. ”

"There are obviously problems with their design!" Guo Tailai laughed. "This shouldn't be that if the positioning signal is not answered, should it decisively start self-destruction within a certain period of time?"

"The overall system is designed like this." The lieutenant colonel was also amused by Guo Tailai's words. He said with a smile: "But it is unnecessary to be specific to each accessory, otherwise the cost is too high. This hard disk is also because of the comparison of the data inside." It is important to have this level of protection."

Oh I got it. Guo Tailai can also imagine that the cost of such a self-destructing device on every important device is indeed very high.

"Is it sure?" General Liu looked at Guo Tailai's observations at various angles, and even took a screwdriver to compare it there. He couldn't help but ask: "If you don't grasp it, don't tamper." Let us have a chance, if it is self-destructive, there will be no chance. This thing is hard to come by..."

"Okay!" Just when General Liu was worried that Guo Tailai was not sure, he was going to give Guo Tailai a serious instillation of this thing, and when he ruined the concept of importance without chance, Guo Tailai flew over there. Answered one sentence.

"Don't pay attention to it!" General Liu thought that Guo Tai was good enough to let him shut up and hurriedly reminded him. "

I mean, it is already open. Guo Tailai picked up a hard disk that looked a little different from the ordinary hard disk, and shook it outside. "The hard disk was taken down. I also removed the power supply. Do I need to disassemble it directly?" ”
