Before the second-generation communication device can be used, the magic imprint must be entered, which is prepared for the [twin imprint], which is equivalent to a preset set of public encryption algorithms.

When the two communication instruments are close, the [Twin Imprint] can be activated, and two different users pre-store the encryption algorithm, which will form a new encryption algorithm and save it 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, using the magic mark for communication as a mark that can be disclosed to the public.

The key to this encryption method is also the eigenvalues ​​assigned to the new algorithm when the two people simultaneously excite the [Twin Imprint].

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

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

And if the message is sent to someone who does not have a second-generation communication tool, it is encrypted with the public communication magic mark, which is very popular in Netheril.

Of course, due to the particularity of [Magic Web Background Communication] (it disappears when received, and there is no possibility of monitoring in the middle), the traditional encryption method may be a little uncomfortable. In fact, as long as it is accurately locked, it is difficult to be intercepted by others. This mainly depends on the level of the caster himself.

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

Otherwise, the magic net background communication is more like a full-frequency broadcast communication spell when it is sent, and the risk of being intercepted is still very high.

…

In the corner of the workshop, after Shado and Garnar activated the twin imprint, a small rune emitting a shimmering light immediately appeared in the communication tool.

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

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

In fact, this kind of rune can also be regarded as a note when storing numbers on a mobile phone on Earth, but the second-generation communication tool is not yet powerful enough to allow users to customize notes, which are automatically generated internally.

Of course, even if someone can completely crack the second-generation communication tool, it is impossible to infer the communication target information only through the small runes projected inside the communication tool crystal ball.

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 look at this small rune carefully. The rune itself has no practical significance, and it has meaning only because it refers to a certain communication target.

"Garnar, you send me a message and say anything."

"Yes, President."

Garner held the crystal ball and said casually, "President, I'm sending you a message, have you received it?"

"…"

Xia Duo suddenly discovered that it was a little embarrassing for two people to use a communication magic device face to face. Of course, if they cooperated with traditional communication techniques, they could achieve silent communication.

However, Shado didn't blame Garnar, but picked up the communication tool, and saw that the only small rune in the crystal ball was constantly 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 in detail.

In fact, the mass production plan he came up with is also a bit risky. It has only undergone a simple feasibility test, and he did it all by himself. In fact, he is not very sure about whether there are bugs.

Xia Duo "clicked" on the flashing rune, and the communication magic device transmitted the pre-received voice information to his ears in the way of traditional communication spells, not directly to the public.

"Garnar, like this, when you go outside, send me messages one by one. Use your fastest speed and don't be afraid to damage the communication instruments. This is originally a test consumption."

After Xia Duo finished speaking, Garner 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 tool on Xia Duo's side began to flicker continuously, and the frequency was getting higher and higher. Seeing this scene, Xia Duo couldn't help but breathe a sigh of relief.

It seems that at least there is no problem with the pre-receive function in the communication management function of the second-generation communication device.

In this situation, if he was still using a first-generation communication magic weapon, it is estimated that his mind would be filled with Garner's numbers.

This is still under the condition of only one person sending the message. If there are more people, dozens or hundreds of people, then his head will be blown off.

However, even if the information transmitted by this 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 communication, all the previously accumulated news 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 cannot temporarily store too much information. If there is too much, the previous ones will disappear, leaving only the latest reception. of.

"Garnar, stop for a while." Shado communicated.

After that, he checked all the information one by one, and sure enough, the numbers started from 1, all of which have reached more than 30. It may be that the information content is less, even 1 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, Shado asked Taring to get a first-generation communication for Garnar, and then the communication commanded: "Next, use the first-generation communication magic weapon, just like just now, start a digital communication from 1, and use your fastest speed. "

Strictly speaking, it should be done by human beings, but it is too wasteful of manpower, and the first-generation communication instruments are similar to human beings.

Xia Duo waited for a while, and the rune in the communication tool in his hand never flickered. At this time, he realized that the too precise locking method of the second-generation communication tool had changed the communication between the two parties from "person-to-person" to The "communication tool to communication tool" is now.

At the same time, this communication magic weapon, UU reading www.uukanshu.com is still a loophole to avoid detection by itself!

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

Xia Duo quickly made up his mind. In fact, he didn't have that much time to make changes. It's more important to make money and build a floating city first. Bug fixes can only be done at 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 locate the person who has applied avoidance detection through this loophole, and it is only possible to determine the existence of the target.

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

If there is no second-generation communication device, he is already being bombarded with information.

It seems that Garner is working hard outside!

Xia Duo thought like this, and then summoned Garner to let him in.
