Chapter 3820: Remote unlock

Lin Rui watched Sergey busy for a while, sweating, and couldn't help but ask him in a low voice, "Can it work?"
"Damn, the protection level is very high. The disassembly itself is a certain degree of difficulty, and after disassembly. I found that there are two ports at the repair box.
Two devices are required to complete the mechanical unlocking. These two special devices are equivalent to the other two sets of keys.
One set is controlled by this company, while the other set is controlled by the manufacturer of the security facility. Both sets must be connected at the same time, that is to say, the authorization of both parties can be obtained to complete the mechanical unlocking. Sergey whispered.
"Why is it so troublesome?" Lin Rui shook his head.
Sergey whispered, "For safety reasons, each security door like this has a special serial number, and different unlocking devices are based on different serial numbers. The security facility manufacturer does this to ensure absolute safety. .
In other words, the products they produce cannot even be mechanically unlocked by themselves. You must work with the customer to complete the mechanical unlocking. "
"Then we are over? We don't have anything. Can't you wear a stethoscope and dial the password slowly with your hands like in the movie?" Wasabi asked in a low voice.
"Are you watching too many movies? And it's still a movie of the last century. Do you think it's prying a safe? This new type of security door is far more than a few sets of passwords.
This is fully computer controlled, connected to the security monitoring office, and even to the equipment manufacturer. Not to mention unlocking, even dismantling the maintenance port is impossible.
These two special ports must have corresponding equipment. Only those two sets of devices together can be regarded as a set of keys. The mechanical unlocking can be completed through the maintenance port.
Think of other ways, unless you blow up the door directly. But do you know the material of this door? This door has multiple layers of alloys, and the strength of the alloys of different materials is different, and the impact resistance of the metal is also different.
Moreover, the shape of this door allows this door to absorb a certain amount of blasting energy. If we want to blow up such a door, we may have to pull the semi-truck C4 over. Sergey shook his head.
"Is there any other way?" Lin Rui frowned.
"I can't do anything, unless...unless I let Kebaan try, we connect the port on the method door to our computer, and let Kebaan remotely control our tactical computer.
See if he has a way to crack the maintenance port that requires a key. Sergey whispered.
"Can it work?" Lin Rui asked.
"The technical team on St. Caesar Island has a very advanced large computer. It can complete a large number of complex calculations. If they can try brute force cracking, it may be possible to open the repair port and let me complete the mechanical unlock." Sergey thought. Thought.
"They are not unlocking the lock, they are computer experts. What does it have to do with opening the door lock?" Lin Rui couldn't help but ask.
"Because this door is controlled by a computer in a completely numerical form. I am so capable and I don't need it. Only Cobain and the others may be able to crack it.
Fortunately, these two ports are common computer data transmission ports. It can be used to dock our tactical computer. Sergey shook his head, "No matter what, they are our only hope. "
"Okay, I can only give it a try." Lin Rui pressed the wireless communicator and contacted Cobain who was far away on St. Kaiser Island. After Lin Rui explained the general situation to Ke Ben, Ke Ben agreed to give it a try.
Sergey connected the tactical computer he carried with him to the unlock port on the door, and Cobain controlled the tactical computer remotely.
A few minutes later, Cobain responded, "I probably know something, it should be a special algorithm.
They solidified the unlock code in the two devices, imported it through the external interface, and could overwrite the program to initialize the security system.
In theory, we can untie it, and it will not take long. "
"It won't be too long, how long is it? I need a precise time." Lin Rui whispered.
"I can't say this well. It depends on the complexity of the code. It may take about two or three hours." Cobain replied.
"Two or three hours is not too long? We are now moving under the eyes of the enemy, and they may find us at any time. Maybe after 10 minutes, maybe less than 10 minutes.
It is hard to imagine that we can stay here for 2~3 hours. After more than an hour at most, the guards should change shifts.
If they find that their companion is dead or missing. This place will soon be surrounded by Fang, and none of us can escape. "Lin Rui lowered his voice and asked if he could try to be faster?
"I will try my best, but to be honest, this kind of thing doesn't have much to do with our wishes. Even if we want to be fast, we may not be able to get up quickly." Cobain answered honestly.
"Is there no other way?" Lin Rui asked in a low voice.
"We lack the opening device and can only simulate a key code, but it requires a cracking process.
This is already a way we can come up with. Using the computing power of a large computer to brute force the crack, it is already very good that we can complete it in three hours. "Cobain replied.
"Well, let your team start work immediately. I will try my best to find a way to prevent the enemy from discovering it." Lin Rui said helplessly.
"How's it going, boss?" Sausage walked over and asked in a low voice.
"It's not optimistic. Even Cobain and his technical support team will take at least 2 to 3 hours to complete the cracking.
And he just cracked the repair port, and the rest of the mechanical unlocking work had to be done by the Russian guy. This may take another half an hour. Lin Rui shook his head.
"It's not necessary." Sergey shook his head, "If they can successfully complete the cracking and initialize this door lock. I only need 5 minutes.
Because after initialization, this door will return to the factory to be installed state. I only need to reset the password to open this door. "
"The key is whether the people at Cobain can complete the cracking work within 2~3 hours. If they can do it, we still have hope. If they can't, then I'm afraid we will be powerless this time." Lin Rui nodded.
"But even so, other security personnel will come over and change shifts in more than an hour. If you suddenly find that all the security personnel on this floor are gone, it will definitely arouse their alertness and attention." Sergey shook his head. .
"Then what are your ideas?" Lin Rui asked him.
"We'd better stay at the top of the stairs less, and kill everyone on this floor. Although this problem can't be solved completely. But it can buy us more time." Sergey replied.
