Chapter 1610 Precise Lock Retention Bug
Before using the second-generation communication instrument, you must first enter the magic imprint, which is prepared for the [Twin Imprint], which is equivalent to a set of public encryption algorithms preset.

When two communication instruments are close, the [Twin Imprint] can be activated, and two different users pre-store the encryption algorithm to form a new encryption algorithm, which is stored on the two communication instruments.

Every subsequent communication will be encrypted using this encryption algorithm.

Of course, it is not difficult to obtain the marks of two people at the same time by using the magic mark for communication as a mark that can be made public.

The key to this encryption method lies in the eigenvalues ​​assigned to the new algorithm when the two people activate the [Twin Imprint] at the same time.

At this point, the two parties do not know the eigenvalues ​​given by the other party to the new algorithm. When decrypting, their respective communication instruments decrypt with the eigenvalues ​​given by their respective users.

Even for the convenience of memory, the name of the communication target can be used as the feature value, as long as you don't say it yourself.

And if it is to send a message to a person who does not have a second-generation communication magic weapon, it will be encrypted with the public communication magic imprint, which is already very popular in Netheril.

Of course, due to the particularity of [Magic Network Background Communication] (it disappears upon receipt, and there is no possibility of midway monitoring), the traditional encryption method may be somewhat unacceptable. In fact, as long as it is accurately locked, it is difficult to be intercepted by others. This mainly depends on the caster's own level.

But relatively speaking, only a more precise encryption method is a more precise locking method.

Otherwise, the magic network background communication is more like a full-frequency broadcasting communication spell, and the risk of being intercepted is still very high.

……

In the corner of the workshop, after Xia Duo and Ganal activated the twin mark, a small rune exuding a shimmering light appeared in the communication instrument immediately.

This is a visual projection formed by using the characteristics of the packaging material of the communication instrument. If it is packaged with other materials, the projection will disappear, but the twin imprint still exists inside the instrument.

It's just that when using it, you need to distinguish and find it by yourself through the changes of the strings of the magic net, which is not as convenient as the current rune.

In fact, this kind of rune can also be regarded as the remarks when the mobile phone saves the number on the earth, but the second-generation communication instrument is not powerful enough to allow users to customize the remarks, and they are all automatically generated internally.

Of course, even if someone can completely crack the second-generation communication magic weapon, it is impossible to deduce the communication target information only through the tiny runes projected inside the crystal ball of the communication magic weapon.

The process of generating runes is similar to the process of data dimensionality reduction. Only part of the data is cut off to form a projection, and a lot of information is actually lost, which is not enough to reverse the information of the communication target.

Xia Duo didn't examine this small rune carefully. The rune itself doesn't have any practical meaning, it only has meaning because it refers to a certain communication target.

"Ganal, send me a message and say something."

"Yes, President."

Ganal held the crystal ball and said casually, "President, I am sending you a message, did you get it?"

"..."

Xia Duo suddenly found that it was a little embarrassing for two people to use the communication magic weapon face to face. Of course, if they cooperate with the traditional communication magic, they can communicate silently.

However, Xia Duo didn't blame Ganal, but picked up the communication magic weapon, and saw the only tiny rune in the crystal ball flashing at the moment.

It looks like once every two seconds, which means there is a new message; if it is once a second, there are at least three messages; if the frequency is higher, there will naturally be more messages.

Specifically, Xia Duo has not tested it in detail.

In fact, the mass production plan he came up with was a bit risky. It only went through a simple feasibility test, and it was all done by him alone. In fact, he was not very sure whether there were bugs.

Xia Duo "clicked" on the flickering runes, and the communication instrument transmitted the pre-received voice information to his ears in the traditional way of communication spells, instead of directly releasing it publicly.

"Ganar, in this way, you go outside and send me messages one by one. Use your fastest speed, and don't be afraid of damaging the communication magic weapon. This is originally consumed by the test."

After Xia Duo finished speaking, Ganal was stunned for a moment. He didn't expect such a test, but he didn't question it, and quickly went out with the communication magic weapon.

Immediately afterwards, the runes in the communication instrument on Xia Duo's side began to flicker continuously again, and the frequency became higher and higher. Seeing this scene, Xia Duo couldn't help but breathe a sigh of relief.

It seems that at least there is nothing wrong with the pre-reception function in the communication management function of the second-generation communication instrument.

In this situation, if he is still using a first-generation communication magic weapon, it is estimated that his mind will be filled with Ganal's counting.

This is still the case where there is only one person sending messages. If there are more people, tens or hundreds of people, then his head will probably blow up.

However, even if the news transmitted by the magic net background communication is temporarily blocked, it will not disappear, but will always exist in the magic net background fluctuations.

As long as he is negligent and locked by the communication, all the information accumulated before will come out in one go.

It can be seen from this that the importance of pre-receiving communication instruments, of course, the second-generation communication instruments are just starting after all, and cannot temporarily store too much information, if there is too much, the previous ones will disappear, leaving only the latest reception of.

"Ganal, stop for a moment." Xia Duo sent a message.

Afterwards, he checked all the information one by one, and it turned out that the number starting from 1 had reached more than 30. It may be that the content of the information is less, even if it is 1, it has not disappeared.

After all, it is a communication device that can transmit and temporarily store image information, and it is not a problem to store some sound.

Then, Xia Duo asked Ta Ling to bring a first-generation communication to Ganal, and then ordered: "Next, use the first-generation communication magic weapon, just like before, start from 1 and send one number at a time, at your fastest speed. "

Strictly speaking, it should be summoned by human beings, but that would be a waste of manpower, and the generation of communication magic tools is similar to human spells.

Xia Duo waited for a while, and the runes in the communication instrument in his hand did not flicker. Only then did he realize that the over-precise locking method of the second-generation communication instrument has changed the communication between the two parties from "person-to-person" to "person-to-person". "Communication instrument versus communication instrument".

At the same time, this communication instrument is still a loophole for him to avoid detection!
"Uh, maybe it can be avoided with a communication management spell."

Xia Duo quickly made up his mind. In fact, he didn't have much time to change it. It's more important to make money to build the floating city first. Bug fixes can only be done during the next "new machine release" .

Anyway, this is not a fatal flaw, because of the particularity of the magic network background communication itself, it is almost impossible to use this loophole to locate the person who has imposed the avoidance detection, and can only confirm the existence of the target.

After adjusting his mentality, Xia Duo slightly adjusted the evasion level of the evasion detection spell, and then he received a lot of information, and the runes in the communication magic weapon in his hand could flash several times a second!

If he didn't have the second-generation communication magic weapon, he would already be bombarded with information right now.

It seems that Gardner is working hard outside!
Xia Duo thought so, and then summoned Gardner to let him in.

　The magic network background communication sends a wide-area probability cloud. When someone receives the information, the probability collapses. There is no intermediate process, so it is impossible to accurately locate it. It can only be judged that there are individuals who have accepted the information.
