Arcane Lord

In fact, the Arcane Empire in the projection plane did not solve this problem. They chose to encrypt the communication array to save users from trouble.

However, if Xia Duo wants to use this method, the design of the communication instrument will become very complicated. Generally speaking, the cost of the encrypted version of the communication instrument will be several times more expensive than the unencrypted version.

In fact, the best way is for the authorities to establish a communication array and keep the encryption process in the communication array. However, in Netheril's situation, it is difficult for all parties to cooperate.

The popularization of communication is conducive to the spread of knowledge, which may not be what everyone wants to see. However, Xia Duo wants to minimize the difficulty for users to use it, so that this method of communication will be more likely to spread.

As long as the threshold is low enough, even if the government does not promote it, spontaneous exchanges among people will soon flourish.

…

Three days passed quickly. On this day, when Xia Duo was communicating with Niya, he was still thinking about the issue of information encryption. He accidentally mentioned this matter. After receiving the message, Niya immediately replied with a silent message. Smiley face.

Messages forwarded through the Tower of Time can also transmit sounds and images. Such a silent expression from Niya made Xia Duo a little confused.

But soon, Niya's explanation voice came over again, "It can be encrypted through [Secret Mark]. Similar spells have already appeared in Giles Tower."

[Secret Mark]?

At this time, Xia Duo's thoughts suddenly opened up. Perhaps it was because he was a time traveler, so when considering problems, he would immediately choose the routines on earth. For example, when he was trying to encrypt the information transmitted through magic, he was still stuck in You cannot escape from the quagmire of algorithms.

But in fact, encryption methods that are simple in form and difficult to crack are not difficult to find in magic. However, Sha Duo has never seen [Secret Mark] encryption and has no corresponding concept at all.

Before, the [Secret Mark] he knew was nothing more than a personal mark. No matter how complex and exquisite the design was, it could still be imitated.

In the game on Earth, for the sake of gameplay, there is a setting that personal marks cannot be copied or imitated. The reason is pushed to the goddess of magic, who is responsible for supervising it. Forging other people's marks will be cursed.

But in the real magical world, the goddess is not so boring as to be the personal imprint administrator of a group of mortals. Her domain is magic network and magic, not order.

It is possible for the Lord of Glory to do such a thing, but the problem is that Sha Duo has never heard of a similar situation.

But if the factor of God is put aside, can the caster himself design an encryption system derived from the [Secret Mark]?

The answer is of course yes. Didn't Niya say that Giles Tower already has such a spell?

Without the permission of Giles Tower, Niya could not directly provide specific details of the spell to Shado, but after further communication between the two, Shado had an understanding of the design principles of this encryption spell.

One party must hold the secret mark of the other party before it can be encrypted, and then the encrypted information is sent out and decrypted by the other party.

The information here is not information transmitted through the communication circle or [messaging technique]. In fact, most of the time it is physical objects, such as confidential documents, secret items and the like.

Once the information is transmitted, the secret mark of the other party held by the caster will also disappear.

In layman's terms, it actually means that the other party prepares a lock and the corresponding key, first gives the lock to the sender, and keeps the key. The sender writes the letter, adds the lock, and sends it out.

After the other party received the locked letter, he used the key left before to unlock it and got the letter.

In Chateau's view, this encryption method is very primitive and cumbersome.

Of course, in practical applications, many locks (arcane marks) can be prepared in advance, but the fact that arcane marks are consumables has not changed.

If the two of them were separated by vast distances, or not even in the same world, and they were chatting at a critical moment, and suddenly discovered that the secret mark was gone, then should they just chat directly, or should they find a way to get the secret mark first?

The actual use experience is very bad.

There are many encryption concepts on the earth, and this kind of direct lock encryption is considered very primitive. Furthermore, the key lock can be turned into a password lock. There is no need for one party to send the lock in advance. It only needs to pass the password before transmitting the confidential information.

Of course, you can go one step further and agree on a password in advance.

Xia Duo's idea was naturally the latter.

…

After breaking off contact with Niya, Sha Duo's mind was filled with inspiration.

First of all, [Secret Seal] is different from the "key" on earth. It actually has the functions of "encryption algorithm" and "key" at the same time.

This makes the encryption form easy, but the actual cracking difficult.

The first step that Sha Duo needs to do is to redesign the encryption spell of Giles Tower into a version that does not consume [Secret Mark]. The original spell itself has nothing to say. For Sha Duo, it is just an inspiration. enough.

Not to mention, Nia offers some concrete ideas.

Chateau is confident that he can completely restore it. Although it may be different from the original version in details, the principle is the same and it is not difficult in itself. The key lies in the inspiration of "encrypting with secret marks".

With inspiration, not to mention Xia Duo, he is a junior mage. As long as he has a certain foundation, it is possible to develop similar encryption spells. And if he has not heard that the secret mark will be consumed, his thinking has not been solidified, and it is even possible. Directly research a version that does not require the consumption of arcane marks.

Xia Duo, who was born on earth, certainly does not have the solidity of thinking of the Nese people. He may have some solidity of thinking on earth, but the longer he stays in the magical world, the more flexible he will become.

And with the wealth of two worlds, he will definitely be able to perform even better.

…

Two days later, Xia Duo completed the design of the encryption spell, which was at the level 1 and was named [Encryption].

Of course, encryption spells are a system, a set of spells, and a corresponding inverse transformation, which is called [Decryption Technique], which is also a level 1.

Now, Xia Duo is designing a new [Secret Mark].

The so-called consumption of the [Secret Mark] actually means sending the [Secret Mark] back to the sender, which is equivalent to the [Recipient's Secret Mark] held by the sender being consumed.

This is because when decrypting, if there is no corresponding [secret mark], the recipient cannot unlock it. (The secret mark cast by an individual cannot remain exactly the same every time)

Perhaps this is why Giles Tower developed such a "lock-delivery" encryption method.

Then, at this time, a [secret mark] that can appear in the hands of the sender and the recipient at the same time is needed. Xia Duo cannot yet achieve an effect similar to "quantum entanglement", but it can be approximately equal.

It's enough to have two identical arcane marks appear in one cast.

In Xia Duo's vision, the future use of communication instruments will be similar to "adding friends on WeChat". Before communication, both parties need to face each other and cast a mark spell together, leaving a complete mark in the communication instruments of both parties at the same time. The same secret mark.

In the future, the communication between these two people can be encrypted or decrypted through this [Secret Seal of Twins].
