In 2006, a research report on cryptographic security in the digital age caused an uproar in the field of scientific research, claiming that if a unique password is used for more than 100 hours, whether it is a digital lock or a keypad lock, the probability of the password being cracked and leaked through various channels will be greatly increased.

Although some people pointed out that this is a security company in order to promote its own new products deliberately sensational, but there is no doubt that this report does cause people to attach great importance to password security, even many of us ordinary people have developed the habit of regularly changing their various account login passwords, not to mention the financial, military, scientific research institutions that use high-level security equipment, important places with higher requirements for information security.

At the beginning, most of the ways to change passwords were randomly replaced, but most of the security passwords of most institutions are shared by many people, and frequent replacement will not only cause many people to remember the wrong password and cause false alarms, but also increase the risk of password leakage more frequently than before.

As a result, soon there are security experts who have designed a logical progressive cryptographic algorithm, simply put, it is to let a password with a long number of digits be calculated in a loop according to a specific calculation formula and law, as long as the user remembers the initial password and the law of operation, combined with the use time and frequency of the password, you can check the current use of the password, this regular encryption method, the security is naturally lower than the random change, but it can effectively reduce the accidents that occur in the process of use, as for the problem of password security, you can extend the number of cipher digits, the calculation process is complicated and other means to solve。

In a certain way, scientists are actually as fashionable as non-mainstream and love to follow trends, once there is something eye-catching and new in the circle, they are embarrassed to say hello to their peers if they don't follow it, so when the new password change security mechanism becomes the general rule of high-end institutions around the world, it is not surprising that the turtles in both European and Asian research institutes will follow this trend.

In addition, it is worth mentioning that whether it is digital encryption or graphic encryption, in order to prevent the password change law from being cracked lightly, the calculation is often extremely difficult and complicated, even if the average person knows the change law, it often takes a few minutes to a few hours to calculate, and even more frustrating even directly design a number jù that non-domain experts can't calculate as a password, for example, I have never calculated the dynamic door opening password of our research institute with the number of celestial orbits jù as the coordinates......

"Graphical deduction is theoretically possible, and it is impossible for them to change the rules of password deduction in such a short period of time," Glebe said cautiously, looking at Xedon, "but we don't have an auxiliary deduction table here, and it is impossible to calculate it......"

"Auxiliary deduction table?" Xie Erdon's face was full of disdain: "Those are all auxiliary tools for lazy people and stupid people who don't have enough brains, check the number according to the table, even a trained orangutan can do it, you just need to tell me the original password and deduction rules......"

"Thousands of chain operations...... Griff added weakly, "and it involves a lot of alchemical knowledge, you ...... Do you know alchemy?"

"I don't know if you still can't talk about it!?" Xie Erdong showed his unique "I can't communicate with you with your IQ", and the meaning of his words was that alchemy, which can only be mastered by people in a lifetime, is just a pediatric for him.

In the end, it was McCourt, who was in charge of the design of the alchemy array security reform, who drew the original array diagram, and patiently explained the deduction and change rules of each line and figure......

Compared with my state of listening to a book from the sky, Xie Erdong frowned and bent his ears, looking contemplative, while I was alert to the gargoyles around me and was anxious in my heart: Is this a score! The big guy on the east tower has begun to slowly stretch his wings and move his claws, and he may pounce down and tear us to pieces at any time!

"Okay, that's the general law of deduction," because of the urgency of time, McCourt spoke so quickly that he was a little out of breath: "Let me tell you about the basic laws of the alchemy array involved......

"No," Sheldon interrupted with a wave of his hand, pulling out from his pocket the pencil head and notebook that he had never left to record the precious inspirations that his clever mind occasionally sparked out of his mind, brushing a few strokes to quickly complete a picture, and then handed it to Griff.

"Erini Four-Ring Prismatic Array!" Griff exclaimed after just one look: "This is the circle I just drawn, how do you know that I didn't leave a sample?"

"Calculate it yourself!" Xie Erdong said confidently: "I don't need to tell me about those basic formula laws, I can summarize them if I think about it myself, now that you start, I can draw much faster than you." ”

The successful restoration of Glebe's magic circle immediately made Sheldon's grandson burst with confidence, and directly pushed away the unlocking circle after the change was staged on the door panel, as for Gleb, who was pushed aside, he looked like he was devastated and muttered to himself: "I studied for fifteen years, and it only took him two minutes to ......"

I was just about to comfort the hapless kid who had been crushed by Sheldon's IQ, when suddenly a terrible scream resounded throughout the audience, and after a long time of brewing, the dragon entrenched on the top of the tower finally woke up completely, and leaped down with a flap of its wings.

At this time, there are two groups of people on the platform, one is the black dog Jiang Shasha's family and the other is us, at this time, they should be like us, blocked out of the password door, and become the target of this dragon's predation, but there are four of them and six of us, they are far away from us, so there is no doubt that we have become the first choice of targets for this beast......

I don't know how the people at the European Institute made the hulking gargoyle fly into the sky, and this guy spread his huge dragon wings and shrouded us in shadows, and then I realized that this dragon was so big that it could slap us together with a wave of its claws......

"Alright!" said a smug cry from Sheldon's side, and the great sense of oppression given to me by the enemy prompted me to raise my foot and kick at the door, but I had just forgotten that the grandson was still standing in the doorway......

"Whew!" said Sherdon, who clung to the door with a strange cry, and the door opened in response to the impact, and when I saw that the way of life opened, I hurriedly pushed and dragged the others into the doorway, and pounced on them.

"Boom!" the dragon's barbed head rushed into the doorway, almost biting us who had just crawled away from the doorway, Mickey hurriedly took out a bottle of reagent from his satchel and threw it over, the liquid inside the bottle shattered and immediately flooded with a large amount of gray foam when it touched the air, and quickly solidified into a viscous and hard semi-solid like undried cement, jamming the dragon's head in the doorway, no matter how it roared and roared.

"Ho~!ho~!" We watched in horror as the hideous dragon head that couldn't move was sealed by the muddy water gushing out, and we gasped together, and suddenly I realized something, looked around and asked, "Xie, where is Sheldon?"

"Woo~!" A suppressed scream came from the side of the dragon's head, and it turned out that the grandson had been stuck to the door panel after I kicked it into the door, and now, it was also buried in the mud...... (To be continued.) )
