The second-generation communication magic weapon must first enter the magic mark before use, which is prepared for the [Twin Seal], which is equivalent to a set of public encryption algorithms preset.

When two communication devices are close to each other, the [Twin Imprint] can be activated, and two different users pre-store the encryption algorithm, which will form a new encryption algorithm, which will be saved on the two communication magic devices.

After that, each communication is encrypted using this encryption algorithm.

Of course, it is not difficult to obtain the sigil of two people at the same time as a magic sigil that can be disclosed to the public.

The key to this encryption method is also the eigenvalues assigned by the new algorithm when two people activate the [Twin Imprint] at the same time.

At this point, both parties are not aware of the eigenvalues assigned by the other party to the new algorithm, and when decrypting, each communication device decrypts with the eigenvalues assigned by their respective users.

Even if you use the name of the communication target as the eigenvalue for the convenience of memorization, as long as you don't say it.

If you send a message to someone who doesn't have a second-generation communication magic device, it is encrypted with an open communication magic imprint, which is already very popular in Nesser.

Of course, due to the particularity of the [Magic Web Background Communication] (disappear when received, there is no possibility of midway monitoring), the traditional encryption method may be a little unsuitable, in fact, as long as it is accurately locked, it is difficult to be intercepted by others, which mainly depends on the caster's own level.

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

Otherwise, the Magic Network background communication is more like a full-channel broadcast when it is sent, and the risk of being intercepted is still very high.

……

In the corner of the workshop, after Xia Duo and Ganar activated the twin seal, a small rune emitting a shimmering light immediately appeared in the communication artifact.

This is a visual projection formed by using the characteristics of the packaging material of the communication magic device, if it is encapsulated with other materials, the projection is gone, but the twin imprint still exists inside the magic device.

It's just that when you use it, you need to distinguish and find it by yourself through the changes in 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 a note when the mobile phone stores the number on the earth, but the second-generation communication magic device is not powerful enough to allow users to customize the notes, and they are all automatically generated internally.

Of course, even if someone can completely crack the second-generation communication weapon, it is impossible to reverse the communication target information only through the small 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 large amount of information is actually lost, which is simply not enough to be used to reverse the information of the communication target.

Xia Duo didn't look closely at the small rune, which had no real meaning in itself, only because it referred to a communication target.

"Garner, you summon me, whatever you want."

"Yes, President."

Garner held the crystal ball and said casually, "President, I'm summoning you, have you received it?" ”

“……”

Xia Duo suddenly found that it was really a little embarrassing for two people to use the communication magic weapon face to face, of course, if it was combined with the traditional communication spell, it was possible to achieve silent communication.

However, Xia Duo didn't blame Garnar, but picked up the communication magic weapon, and saw that the only small rune in the crystal ball was constantly flickering at the moment.

It looks like it's about once every two seconds, which means there's a new message; If it's once a second, there are at least three messages; The more frequent it is, the more messages there are.

Specifically, Xia Duo did not test it in detail.

In fact, his mass production plan is also a bit risky, only after a simple feasibility test, and he did it alone, whether there is a bug or not, in fact, he is not very sure.

Xia Duo "clicked" on the flickering rune, and the communication magic device transmitted the pre-received voice message to his ears in the traditional way of communication spells, rather than directly releasing it to the public.

"Garner, in this way, you go outside and send me a number of messages, with your fastest speed, don't be afraid of damaging the communication device, this is originally a test consumption."

After Xia Duo finished speaking, Garnal paused for a moment, he didn't expect it to be such a test, but he didn't question it, and quickly went out with the communication device.

Immediately afterwards, the runes in Xia Duo's communication magic weapon began to flicker continuously, 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 device.

In this situation, if he was still using a generation of communication magic weapons, it is estimated that his mind would be filled with Garner's count.

This is still a situation where only one person sends a message, if there are more people and there are dozens or hundreds of people, then he estimates that his head will blow up.

However, the message transmitted by this kind of magic network background communication, even if it is temporarily blocked, it will not disappear, but will always exist in the background fluctuations of the magic network.

As long as even if you are negligent and locked by the communication, the information accumulated before will pour out.

It can be seen that the importance of pre-receiving the communication device, of course, the second-generation communication device is just starting after all, and it can't temporarily store too much information, if there is too much, the previous one will disappear, leaving only the latest one.

"Garner, stop for a moment." Shado said.

After that, he checked all the information one by one, and sure enough, the number counted from 1 had already reached more than 30, maybe the information content was less, even if it was 1, it had not disappeared.

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

Then, Shado asked Taling to fetch a generation of communication for Ganar, and then sent a message and ordered: "Next, use the generation communication magic weapon, and send a number of messages starting from 1 as you did just now, as fast as you can." ”

Strictly speaking, it should be used to cast spells and transmit spells, but that would be too wasteful of manpower, and the communication of a generation of magic machines is similar to that of people.

Xia Duo waited for a while, and the runes in the communication magic weapon in his hand did not appear strobe, and then he realized that the overly precise locking method of the second-generation communication magic weapon had changed the communication two sides from "person to person" to "communication magic device to communication magic device".

fo

At the same time, this communication magic device is also a loophole that it avoids detection!

"Well, maybe you can use the communication management spell to prevaricate."

Xia Duo quickly made up his mind, in fact, he didn't have that much time to change, it was better to make money to build a floating city first, and the bug fix or something could only be done when the next "new machine was released".

Anyway, this is not a fatal flaw, because of the particularity of the background communication of the magic network itself, it is almost impossible to locate the person who has imposed evasion detection through this loophole, and it can only be determined that the target exists.

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

If he hadn't had a second-generation communication weapon, he would have been bombarded with information at this time.

Looks like Garner is working hard outside!

Thinking so, Shado summoned Ganar to let him in.
