Chapter 258： Signal safety; liberating miners

"Of course, as long as it's the boss of Kent, I will believe and listen."

Joni answered almost without stumbling, causing Kent to smile a little.

This proves that he really did not misunderstand the person.

Then he briefly talked about his plan to Jonny.

Jonny heard that the whole person was dumbfounded. He originally thought Kent was just going to take him and run together, and at most he would bring some food and weapons. He never thought that Kent was going to dig directly. In the corner of the Otto Refuge, he actually wanted to take the miners away.

This is unbelievable.

Isn't he worried about being caught by Otto?

When Jonny asked this question, Kent smiled.

"Otto has already escaped, and what remains in the shelter is just a stand-in. More than that, Otto, who has escaped, has been caught by my people, and is now moving towards the shelter, and will cooperate with my actions. Let the Otto Sanctuary completely mess up, and then give us a chance to escape."

In fact, Kent didn't expect that this task would be so smooth, and he went to this point without any obstacles, so until now, he himself is a little unbelievable.

But now I have to send the arrow on the string. Otto’s stand-in can’t be pretended for a long time. After all, it’s still the time when the three major shelters are fighting. Every day there are countless pieces of information gathered in front of Otto, and there are countless orders from Otto. He said that even if "Otto" closed the door to everyone and only issued an order through a door, it is estimated that it can only maintain stability for two to three days at most.

Two to three days later, don't talk about smart people, as long as you are not too stupid, I am afraid you can feel something wrong, and then discover the fact that Otto has escaped.

When the sanctuary becomes chaotic and he does not bring the miners out, the chaotic situation will become an obstacle instead. It is better for him to act first and mess up the situation by himself, so that the chance of a smooth escape will be higher.

And don’t forget that Iby had expressed his willingness to join the forces behind him before, and it would be a good choice to make use of Iby at this time.

"Listen, you just go to the gate and wait now, just find a room with no one to hide, and don't be discovered by others. When I hear from me, when I will come out, you just need to follow up, you know? There is also this communicator, you can take it, you can contact my people, when I bring the miners up from the mine, you will immediately contact my people and let them respond from the outside, the code is..."

After speaking, Kent turned and left without any hesitation or delay.

Jonny was dumbfounded, and it took him a long time to come back to his senses. He immediately rushed out of the room and walked quickly towards the door.

At the same time, he quietly put the communicator in his pocket, not daring to let others see it.

In fact, there is no need at all. He is an old man in the sanctuary. He will be Otto's subordinate before the end, and no one will doubt him.

Jonny was also a little worried, worried that when he contacted the outside, he would be caught by the people in the shelter.

It's a pity that Kent walked in a hurry and didn't tell him that this kind of worry was unnecessary.

What Kent uses is a communication technology similar to radio. In theory, this communication method is actually very easy to intercept.

Master asked An Kai about this question before. After all, he is the chief of the police, and he still knows a little bit about these things.

There are too many ways to intercept radio signals. Some taller ones, such as spy satellites, use electronic interception equipment on the satellite to intercept electromagnetic signals in the air. Due to the satellite's high position, high wireless gain, large reconnaissance area, and flight speed Fast and other characteristics, so it can successfully monitor all strong and weak radio communication signals on the ground.

The same is true for spy planes, where advanced electronic and communications interception equipment is installed in military, civilian or unmanned aircraft to intercept electromagnetic signals in the air.

The spy ship installs electronic interception equipment on the ship to intercept and intercept various radio communication signals in the coastal waters or near the target.

Of course, the most common one is ground electronic interception equipment. That is to use some places on the ground, such as consulates, embassies, and dispatching agencies, to set up ground electronic interception stations to intercept electromagnetic signals.

As for Masters, if they have this need, they can use their legal status like the police to intercept them, or use the miniature camouflage listening devices they carry with them to intercept electromagnetic signals in the air, and so on.

The related equipment itself is not a prohibited item. After all, it was a prosperous modern society before the end. People have various communication methods. Even the government and the military have specialized communication channels. Generally, It’s impossible to intercept the military and government’s information on civilian equipment, so there is no restriction on the sale and use of relevant civilian equipment on the market. So Otto has similar equipment in his hands.

But An Kai told him that there was no need to worry at all.

Because their encryption method is not the same as ordinary people.

Generally, there are several ways to prevent radio signals from being intercepted.

The first is to improve the level of communication security technology. The radio system uses burst communication, frequency hopping communication, digital communication, spread spectrum communication, directional communication and other technologies to reduce the chance of signal interception. Continuously improve information encryption technology, and secret information is transmitted after encryption.

Secondly, communication security technical testing and technical preventive measures can be strengthened, and communication equipment should be frequently checked for security and confidentiality technology to plug loopholes; secret-related departments prohibit the use of cordless phones, and secret-related communication facilities should take shielding measures to prevent electromagnetic radiation from leaking.

Finally, you can strictly abide by the confidentiality regulations, and telecommunications workers and confidential communication workers must strictly abide by the communication confidentiality regulations.

The communicator used by An Kai, or the communicator he gave to Master, represents the first direction.

In these communicators, there is a small chip specially used for transcoding. All communication content can be converted into special signals through this small chip.

If there is no special chip, no matter how advanced the equipment is, only a noise can be captured. Of course, An Kai didn't understand the specific programming techniques in it, and Master didn't understand either, and they didn't even bother to understand this kind of thing. Anyway, Ankai only needs to know that there is a systematic power in it, and Master only needs to trust Ankai, which is enough.

Jonny is still an outsider now, and he doesn't even know who is behind Kent.

He naturally cannot understand the many connections behind this.

As the future deputy defense minister of the shelter, Master himself was once the chief of the police, and of course he knows the importance of communication security.

In fact, when he and An Kai, and other people in the shelter, they had a meeting together, they had reached a consensus long ago.

It is not just this operation. In the future, as the number of shelters' bases continues to increase and the coverage area continues to grow, various communication methods will gradually appear.

Once the communication leaves the "face-to-face", there is always the possibility of being intercepted and deciphered by others. The risks involved are too great.

The world has been pushed forward for several decades, and large-scale wars have emerged. The importance of communication security in wars is hard to mention.

If it is accidentally searched and intercepted by the enemy, the enemy can obtain information such as its technical parameters, working characteristics and the location of the radiation source through analysis and identification, and find out through the analysis of the signal characteristic parameters and location parameters of the radio. The composition, command relationship, and communication rules of one's own communication network can be used to find out the type, quantity, deployment and changes of radio communication equipment, so as to further determine the location of one's own command post, combat deployment, and action attempts.

In addition, through long-term or regular reconnaissance and surveillance of its own radio communications, the enemy can also collect and accumulate information on its own radio communications in detail, establish and update the intelligence database of its own command and control communications system, and evaluate the status and status of its own radio communications equipment. Capabilities provide a basis for formulating communication countermeasures operations plans, researching communication countermeasures strategies, and developing communication countermeasures equipment.

Even further, directly disrupting information, or forging information, creating traps and ambushes, etc., are all things that can be fatal.

Therefore, An Kai pays more attention to communication security than Master, so since he can take out this communicator, it means that this thing is safe, and at least it is not so easy to be cracked. of.

Jonny didn't know these things, but he chose to believe Kent, and when he came near the door, he pushed the door directly into the room where he lived before.

This room has been vacant since they moved out. Now, after a period of fighting, the population of Otto Refuge has dropped sharply, and a lot of rooms have been vacated.

Therefore, Jonny's actions did not attract anyone's attention, and he hid himself smoothly.

At the same time, Kent also went to the basement smoothly.

It's just that he didn't go straight down. Instead, he turned around and went to the basement floor. There was a combat team here, but his job was not to guard the miners, but to guard the arsenal.

Most of the guns, ammunition and protective equipment in the Otto Refuge are placed here, except for a few high-level people, everyone needs to hold a special order to come and get the equipment alone. Usually, Otto specially dispatched personnel to be responsible for the storage and delivery of weapons and equipment. As for this combatant, his job is just to protect this place from sneaking in.

Of course it was originally like this, but now Otto has been arrested outside, and the people inside still don't know anything.

The person in charge of weapons in and out of the warehouse did not receive any orders, so when Kent appeared here, the fighter in charge of the goalkeeper was shocked, then his complexion changed slightly, and he subconsciously wanted to raise his gun.

"You can think about it, do you understand what is going on now?"

As Kent spoke, slowly approached the other party.

"Now put down the gun and follow me, I will bring you a better life. If you shoot and kill me, you will die when this place is destroyed, and my companion will not let you go."

He was less than ten steps away from the opponent at this time.

The combatant in front of him was a young man in his twenties.

It still looks very immature.

The hand holding the gun was trembling.

"You, don't come over, I'll tell you...My duty is to guard this place, and I can't let you take anything away, otherwise the Old Master Odor will kill me..."

"Naive, do you think he can survive? Don't you know what the shelter is like?"

There are eight steps left.

"Druut and Farman are holding back their hatred to kill Odo. Now everyone in the shelter is in danger. Are you going to bury Odo?"

There are six steps left.

"Stand...stop..."

"Put down the gun and listen to me. I will give you this opportunity to follow me, leave here, and go to a better shelter, where there is enough food and clean water, no one oppresses you, you just need to work hard, You can live safely, just like before the end."

There are four steps left.

"I really shot, I really..."

"You are still young, don't you want to continue to live? Do you really want Otto, not even your own life? Think about it, is he really nice to you?"

Three steps left!

Kent jerked.

However, just as he rushed up, the young man put down his gun.

"I, I think you are right..."

The young man watched Kent suddenly rushed to him in a daze.

Kent did not expect that the other party would give up resistance at this time.

But this is also good.

"That's right, open the door, prepare a weapon for me, and wait for me here. When I come back, I will open it up completely."

Kent patted the young man on the shoulder, and quietly put away the knife.

Since the other party is willing to be obedient and willing to give up resisting, then of course he will give the other party a chance to survive.

But it is only limited to this young man. As for the few people who guard the mine below, honestly, they can't do this.

The fact that those people can be sent here to perform such a task is very telling in itself.

And unlike this young man's one-on-one situation, there are a total of five people guarding the entrance and exit of the mine. Kent definitely can't use this method to force each other, so it can only be a big murder.

Five minutes later, he carried a pistol and came to the depths of the mine.

I found an old man who had communicated with me.

"It's time ~ www.novelhall.com~ The people who brought you, and everyone else, will gather at the exit of the mine together. When you hear the gunshots, you will rush out. I have taken care of everything."

After that, Kent turned and walked back.

Behind him, the old man waved his hand, and one after another miners started to stand up from the bed and followed silently.

Kent waited for about ten minutes, and there were already hundreds of miners in the back. There are also some people who haven't followed, they are cowards who are timid and afraid of being killed, even if someone guides them, they don't dare to take risks. Kent can't do anything about this kind of people. Although they look pitiful, they can only let them fend for themselves.

After everyone was ready, Kent took the lead and walked forward, just as before, no one was in charge when he came, and no one when he left. Only this time, when he walked behind the four combatants, he suddenly took out his pistols and killed three of them in one breath.

The last one reacted, but it was too late. He just turned around and was shot to death by Kent.

The sound of gunfire completely broke the silence. The miners below rushed out and picked up the weapons on the ground, including four pistols, two submachine guns, and two machine guns, and then rushed straight out under the leadership of Kent.
