Break out of the courtyard

The next morning, Tang Hu, who had not slept all night, waited until Zhang Heping and Chen Shuting walked out of the hotel room, then hurriedly followed them and reported in a low voice:

"Son-in-law, Logistics Procurement Manager Yang Wenmao is missing. His family left Hong Kong on July 7, saying they were going to travel to Europe, but I checked Kai Tak Airport last night and there was no boarding information for them."

"We initially suspected that Yang Wenmao broke into your villa after pouring gasoline and setting it on fire last night, and then stole your computer hard drive!"

"In addition, the community security arrested two Japanese people. They were the two Japanese veterans who escaped from Huadu."

"After interrogating the two Japanese veterans, we found three ceramic lipstick guns under the seats in the meeting room that they had brought into the venue through their anuses. Each of them was a single-shot bullet, and its power was no less than that of a single-shot revolver."

……

Zhang Heping listened to Tang Hu's report all the way to the restaurant downstairs before asking, "Where are those computer hard drives?"

Tang Hu had some doubts, but he didn't dare to express his guess at this time, because Zhang Heping's reaction to this matter was really too abnormal.

"The computer hard drive has not been found yet. Please give us two more days to investigate!" Tang Hu lowered his head and replied without looking at the looks from the bodyguards around him.

Zhang Heping did not comment. After having breakfast on the second floor, he went to the Canton Fair Complex.

He had already sent his wife and children back to the capital ahead of time, so how could he not give any special care to those problematic managers!

...

On the morning of July 7, the last day of the Information Technology Security Exchange Conference, Zhang Heping gave brief answers to the questions that Tang Wei had collected in the previous two days.

The issue that these people are most concerned about is Internet security, and they want Zhang Heping to make the source code of Security Guard public.

"Until I find a more secure information technology security defense method, the source code of Security Guard cannot be made public!" Zhang Heping looked at the questions recorded on the laptop and said lightly to the microphone on the table:

"Let's not talk about that for now. I also need to use security guards to ensure the security of electronic trading data of Hong Kong Island Securities and Japan Island Securities."

"As far as the ownership of SafeGuard is concerned, you have no right to ask me to disclose it, and I have no obligation to disclose the source code of SafeGuard to anyone. Otherwise, what is the point of patent law?"

"Of course, you can also unite to sanction the Peace Group, hum..."

Zhang Heping snorted coldly, ended the question about the source code of Security Guard, and then talked about Internet defense measures and countermeasures against hacker attacks.

When the meeting was about to end at noon, a Magnesian asked sarcastically, "Mr. Zhang, are you really not afraid of joint sanctions from all countries against the Peace Group?"

"Humph!" Zhang Heping stood up, picked up the microphone and replied calmly, "Without the European magnesium market, won't I be able to develop the northern Jiangsu market, as well as the Chinese and African markets?"

"Mr. Zhang said it well! Our South African market is always open to you." One of the few black brothers in the venue expressed his position to Zhang Heping loudly in Eagle language.

"This is the end of the morning meeting. The afternoon exchange meeting will not repeat the questions from the morning. Everyone should plan your own questions. Time is precious!"

After he finished speaking, Zhang Heping left early again.

...

"You Japanese people, have you got Zhang Heping's computer hard drive?"

As soon as they left the Canton Fair complex, three Japanese people presented a big gift to their magnesium father.

"We just got it last night!" A short, thin, middle-aged Japanese man with a respectful face said to the leader of the Magnesium team, "Please help us, Mr. Pete, to crack the technical information on this hard drive. It would be best if we could organize a meeting this afternoon to ask for methods to crack the encrypted data."

"Let Zhang Heping teach us how to crack the encrypted data, and then crack his computer hard drive. If he finds out, he will be pissed off by you Japanese people!"

"No! As soon as we raise the question of how to crack the encrypted data this afternoon, Mr. Zhang will think that we took his computer hard drive." The middle-aged Japanese man said with a sly smile:

"So, I would like to ask you all to put pressure on him this afternoon! Since he is unwilling to disclose the source code of Security Guard, then share with us the method of cracking the encrypted data; if he refuses, hehe..."

...

While Zhang Heping was having lunch, Tang Hu, the security manager of the Umbrella Company, came over again and reported in a low voice: "Boss, Yang Wenmao's body was found by the Hong Kong police. It was said that he was found by a passerby in Repulse Bay and the police were called to handle it."

Zhang Heping did not respond. Tang Wei, who was eating at the same table, glanced at his father Tang Hu and wanted to say something, but was stopped by his father with a slight shake of his head.

Tang Hu thought that it would be difficult for him to get away with it this time!

In their own nest, under such strict protection, the house was actually stolen by a traitor!

I'm afraid his career as a security manager has come to an end...

"The news from President Wei is that the computer hard drive still hasn't been found!" Tang Hu said again, and when he saw that Zhang Heping still ignored him, he had to say goodbye and leave in disappointment.

Wei Chunqiao, the general manager of the Umbrella Company, was so frightened last night when he heard that Zhang Heping's computer hard drive was stolen that he rushed to Shenzhen overnight. As soon as the port was opened this morning, he took one of his men and returned to Hong Kong Island to deal with the aftermath.

Then, Wei Chunqiao learned that the purchasing manager Yang Wenmao was missing, and thought of the letters of complaint he had received in recent months about Yang Wenmao's multiple meetings with Japanese people.

Speaking of which, if this happened last year, the moment Wei Chunqiao received the report, he would have taken the report to Zhang Heping for instructions, regardless of whether it was true or false!

Now, Wei Chunqiao missed the best opportunity to take preventive measures because he thought "his old brother is not that kind of person."

Now, Wei Chunqiao doesn’t know how to face Zhang Heping’s anger!

Is Zhang Heping angry?

Obviously not!

This guy had lunch, took a nap in the car for half an hour, and then walked into the Canton Fair complex to wrap up the Information Technology Security Exchange Conference.

"Heping!" Director Wang Sumei saw Zhang Heping and his group coming in, and immediately stood up from the small stool, holding a brown paper bag, and greeted them happily, "Fortunately, I have fulfilled my mission. The samples of mobile phone cards and bank cards have been made!"

"There is also a sample handheld card swiping machine in the bag, and a 2G mobile phone with a card slot sent by Tang Qiang."

"You've come just in time!" Zhang Heping happily took the brown paper bag and said with a smile, "This morning, the Magnesian people were still threatening me with the joint sanctions against the Peace Group. I'll remind them later to remember to sanction mobile phone cards and bank cards as well!"

"We are actually hoping that those foreigners will sanction you so that you, a bad boy, can invest in the country with peace of mind." Director Wang responded with a smile, then pulled Zhang Heping aside and asked in a low voice about what happened in Renheyi Community last night.

"I heard that your computer hard drive was stolen by a traitor?"

"Hmm..." Zhang Heping responded with a snort. He was already used to Director Wang getting the news so quickly.

Zhang Heping actually knew which people were sent from the mainland to join the Umbrella Company.

Otherwise, after catching the Japanese islanders, there is no need to lock them up in a small dark room; just send them directly to the high seas to feed the fish, which will make you feel better and save you food!

Wang Sumei asked worriedly, "Did you lose any important information?"

Zhang Heping thought about it and realized that this matter still required outsiders to play a role with him, so he was silent for a while before saying to Director Wang, whose face was becoming more and more solemn: "The materials of the two meetings that were sorted out recently are all above!"

"The nuclear power plant's information is also on it?" Wang Sumei was shocked!

The two meetings are naturally the information technology security exchange meeting currently being held, and the nuclear power plant construction bidding meeting on August 8st!

Although Wang Sumei had made the worst plan, her mood became completely ruined when she heard Zhang Heping personally admit that the nuclear power plant construction information had also been stolen.

"My computer hard drives are specially encrypted, and the Japanese can't crack them in a short time."

"Japanese? Have you found the person who stole your hard drive?"

Zhang Heping glanced at his watch and said, "Auntie Wang, I have to go to a meeting! The data on that hard drive may be a little ahead of the Japanese, but it is an iterative product for me."

"It's like my leftover food, which was left overnight. If they stole it, they stole it. Just let it go!"

Of course, Zhang Heping was open-minded. 95% of the technical information from the two conference materials left by this guy on his hard drive was true. It was just that the technical information of the nuclear power plant did not record the thorium-based molten salt reactor, but the uranium reactor technology that had some hidden dangers.

Now, Zhang Heping is worried whether the Japanese can crack his somewhat primitive encryption method after getting his computer hard drive.

However, after he manipulated the situation behind the scenes and “randomly” selected five experts to come on stage to discuss the topic, his worry turned into a gloomy look.

"Mr. Zhang, we understand why you don't disclose the source code of the security guard. After all, this security guard can bring you a lot of income!" An old man from the French country said seriously:

"If we want to start with encryption to ensure Internet information security, which encryption methods do you think are easy to crack and which encryption methods are not easy to crack?"

“Here they come!” Zhang Heping looked towards the darkened auditorium without any lights, staring at the direction of the Japanese people, sneering in his heart, “These bastards are so bold that they dare to team up with the Europeans and Americans to get the solution from me.”

"Mr. Zhang?" The Frenchman asked, "You organized a technical exchange meeting, so you wouldn't keep even the encryption technology secret, right? You don't have any business in this area, so it won't cause you any loss if you tell me about it!"

"Humph!"

Zhang Heping snorted coldly, picked up the brown paper bag that Director Wang had just given him from the ground on his right, and took out the contents.

Then, he picked up a fingernail-sized mobile phone card and said with a smile, "This is a mobile phone card. It can store the owner's personal information, as well as the names and phone numbers of contacts."

"This is a matching card-slot phone!" Zhang Heping opened the battery cover, removed the battery, installed the SIM card, and then showed the back of this white, elderly-style phone to the other five people on the stage.

"Depending on the encryption advantage of the SIM card, calls and communications on this 2G phone will be more secure."

"So, this gentleman said that I have no business in encryption. I'm afraid I'm going to disappoint you." Zhang Heping said as he handed the white elderly phone without the battery and back cover to Professor Li on his left, the female expert whom Zhang Heping recognized yesterday afternoon and whom he had met once in Guangcheng.

"This is a bank card. It can be called a bank savings card or a credit loan payment card in the future." Zhang Heping held the POS card reader in his left hand and a pure white plastic card in his right hand. He smiled at the camera in front of him and said:

"I just need to insert a real-name authenticated mobile phone card into this card machine and bind it to the bank account of the card machine owner. Then, I can..."

Zhang Heping inserted his bank card into the card reader, handed it to the black man on the right, and explained with a smile:

"The encrypted identity information on the bank card is recognized by the card swiping machine, and then the 2G data network is connected through the mobile phone card in the card swiping machine to transmit the transaction amount to the bank server. Finally, the money in the bank card owner's account is transferred to the bank account bound to the card swiping machine owner according to the card swipe amount!"

"It sounds complicated, but it's actually very simple to operate. Insert the bank card, and the cardholder enters the password to confirm the payment transaction, and the deal is done!"

"In addition, information encryption technology is originally a part of information security technology. It's just that you haven't thought of the application scenarios of encryption technology, so you think it is worthless to me!"

When Zhang Heping's unobtrusive first advertisement came out, not only were the five participants on the stage surprised, but even the audience seats became noisy.

A man from the country said solemnly to the people around him: "Once the use of this bank card is known to domestic bankers, they will strongly oppose our sanctions against the Peace Group, and will also find ways to cooperate with the Peace Group to promote the use of bank cards!"

"The idea of ​​a credit card payment card, coupled with the card swipe machine transaction, will probably make every banker crazy!"

"The bank is going to get rich! Mr. Zhang is going to make a fortune again!"

"No wonder he is not afraid of our sanctions. With this bank card in hand, banks in various countries will seek cooperation with him!"

"Those bankers and capitalists won't be polite to us who work in technology, and the higher-ups will also be influenced by their opinions."

"Everyone!" A middle-aged Japanese man suddenly came over and whispered, "As long as we can crack that thing, we may also be able to get the technology to make mobile phone cards and bank cards!"

After this reminder, all the European and American people quickly discussed countermeasures.

After a while, the group of European and American people began to protest loudly.

"Mr. Zhang, you organized an information technology security exchange meeting. You can't talk about this or that. What else can you discuss?"

"Mr. Zhang, since you said that mobile phone cards and bank cards use encryption technology, you can introduce them to us here. In the future, if bankers come to us for consultation, we can also help you promote them."

"Mr. Zhang, I'm just giving you a brief introduction to encryption technology. I'm not asking you to disclose the full set of technology. We can always communicate about it, right?"

As more and more European and American people spoke up, Zhang Heping was finally forced to agree. He started with the encryption of the optical card and introduced some basic encryption methods he had mastered.

By the way, the computer information security technology at that time was really primitive, and many methods had not yet been thought of.

Zhang Heping, on the other hand, just relied on the convenience of plug-ins to learn more advanced knowledge than others.

It was this advanced encryption technology that he mentioned that silenced everyone in the studio.

The security guards present were not allowed to speak without permission due to their professional requirements, and the translator who joined in the middle was asked to remain silent by the foreign experts.

In contrast, the mainland computer experts who had just attended the meeting this morning were a little surprised. This group of foreigners were making a lot of noise just to learn the technology from the young man on the stage!

Who is this young man?

He actually used threats and bribes against these foreign experts in public just to listen to him talk about computer technology.

Just as those real scholars were listening carefully to Zhang Heping's in-depth and easy-to-understand explanation of encryption technology, Old Pete, the leader of the Magnesium team, spoke again at the reminder of the middle-aged Japanese, interrupting this brief academic atmosphere.

"Mr. Zhang, if I ask you to create a hacking software, would it be easy to crack the encryption methods you just mentioned?"

Old Pete's abrupt remarks did not receive a response from Zhang Heping, because the old man was not one of the communicators on the stage.

However, the Frenchman on the stage was very sensible. He immediately asked old Pete's question again, which allowed Zhang Heping to answer.

"No matter how complex the encryption method is, the password is set by humans!" Zhang Heping said calmly:

"Most of your QQ passwords and forum passwords are 123456. More complex ones are birthday passwords, and even more difficult ones are letters and numbers, or punctuation marks."

"So, sometimes you don't need to know any technology to crack a password..."
