I was framed for taking the civil service exam, so I joined the National Security Bureau

"Radio cryptography?"

When Zhang Xing heard these words, he couldn't help but repeat them in surprise.

Because as far as he knew, radio cryptography was something that only intelligence personnel needed to learn. As a member of an action team, why would he learn this stuff?

And radio cryptography, a pure digital game, is not something that ordinary people can learn. Generally speaking, professional radio cryptography talents usually need extremely high digital talents.

For example, some radio cryptography talents in the intelligence department all have certain digital talents, and then they are discovered by the intelligence department, and then brought into the intelligence department for long-term professional training, and finally they can become qualified radio communication personnel.

And this kind of radio communication personnel has a very high status in the entire intelligence department. The reason for the high status is that this kind of talent is scarce and difficult to train.

The so-called radio, also known as radio waves, refers to electromagnetic waves propagating in free space (including air and vacuum).

According to the theory of radio, later generations developed radio cryptography equipment, which is commonly known as "cryptographic radio station", also referred to as radio station.

And "cryptographic radio station" refers to communication equipment that encrypts information according to a certain procedure.

Through this communication device, countless sets of permutations and combinations of numbers or letters can be evolved, and these permutations and combinations are a set of password systems.

The password system also includes two concepts: password symbols and algorithm engineering.

Take the most commonly used Morse code to explain.

The symbol [.] in the Morse code is a beeping sound when sent, and [-] is a tapping sound when sent. A beep is a time length, and a tap is three time lengths.

If you use Morse code to send a text message, the sound can be transmitted on the radio through password symbols of different time lengths. The receiver on the other end of the radio can arrange specific symbol information through the password symbols, and then take these symbol information, and then find a special Morse code translation to translate the content of the text message.

Every country, specifically every military unit, has its own specific code translation. These code translations are usually developed by the scientific researchers of the unit for internal communication. Once the code translation is stolen by the enemy, it will inevitably cause a large-scale loss of one's own intelligence, and finally cause an irreparable disaster.

With the advancement of technology, cryptographic radio stations have been developed to the point where they can communicate with spy satellites in space, and then spy satellites can be used to communicate with spy radio stations in different parts of the world.

The main way of communication between modern spies is also to use radio stations. In fact, many confidential intelligence of the Intelligence Department is collected through satellite cryptographic radio stations.

But this is what the Intelligence Bureau has to do. What does it have to do with an intern in the Action Team?

Seeing the puzzled look on Zhang Xing's face, Geng Jianhui naturally guessed what he was thinking.

Geng Jianhui then smiled bitterly and said:

"It was not me who asked you to learn radio cryptography, but Captain Jiang. He said that you have a certain talent for numbers and a flexible mind."

"Although members of our Action Team are rarely exposed to radio cryptography, as an outstanding member of the National Security Team, if you can learn radio cryptography, even if you only learn some superficial knowledge, it will benefit you for life."

To be honest, Zhang Xing's science grades in recent years are indeed good, especially his talent in mathematics. In the college entrance examination that year, he scored 142 points in mathematics.

However, Jiang Yu suggested that he learn radio cryptography, which was probably related to the code question Song Changlin gave him last time. Zhang Xing guessed that Jiang Yu might feel that he had a certain talent in cryptography based on the assessment.

Although Zhang Xing did not think he had a talent for cryptography and was not willing to learn such heavy and boring knowledge and skills, the leader had said so, what else could he do? He could not just refuse.

Seeing that Zhang Xing did not speak out, Geng Jianhui smiled again and said:

"Captain Jiang also has good intentions. He has high hopes for you. It just so happens that the bureau has recently established a rat extermination team. If you join it at this time, you can learn some radio code knowledge more or less, which will be helpful for your future work in the action team."

The rat extermination team, as the name suggests, actually literally means a spy extermination team.

In the National Security Bureau, there are two titles for spy members. The action team calls spies shrimps, big fish, etc., while the intelligence department calls spies rats and big rats.

After asking, Zhang Xing learned that this rat extermination team, was created by a senior cryptographer from the Intelligence Department. Moreover, this cryptographer has a special status. He was transferred from the Kyoto National Security Bureau after Director Song Changlin submitted numerous applications.

Although Bonan City is also a municipality, it is not large in area, so talent resources are relatively scarce, especially in the field of radio cryptography, which has always been in urgent need.

Therefore, Director Song Changlin has always wanted to arrange an excellent cryptographer to come to the Bonan National Security Bureau to guide the work and help build a complete radio cryptography team. Considering that Bonan City is located in the coastal area and the spy forces are relatively complex, this is why this cryptographer who has been famous in the Kyoto National Security Bureau for a long time was transferred here.

It is worth mentioning that this cryptographer, code-named Violet, is said to be a junior sister of Captain Jiang during the police academy period. The main purpose of her coming to the Bonan City National Security Branch to form a rat extermination team this time is to help train a professional radio cryptography team, which includes not only professionals from the Intelligence Department's telecommunications group, but also some newcomers with digital talents.

Other action teams, including leaders of other departments, also intended to train people in this rat eradication team, but the Violet Code Officer had extremely high requirements for people who entered the rat eradication team to learn codes. So far, no team members from other departments have been approved to join the rat eradication team.

But Zhang Xing was different. Because of the friendship between Captain Jiang and the Violet Code Officer, after Captain Jiang made this request to the Violet Code Officer, the other party decisively agreed after reading Zhang Xing's information and various assessments.

In other words, Zhang Xing took a shortcut through Captain Jiang.

Although Captain Jiang helped him make this decision without asking if he was interested, Captain Jiang did it out of cherishing talents, not to mention that this rat eradication team seemed quite interesting, so Zhang Xing did not refuse after learning about these situations, but Zhang Xing did not say anything, but just told the team leader Geng Jianhui that he could try it.
