Chapter 375 Analysis
Fan Keqin said: "This encrypted message is Okubo Xiaoyun, who told Yamaguchi Yoshimune to send it only when he retreats. What is this for? Now we can say that we have arrested all the people involved in this case. No one can fight this The encrypted information is related, that is to say, there is another person we don’t know, or a group of people in the local area. After all, the platform he wants to send this information is our local Minsheng Daily in Chongqing. If you are outside, if you want to see this It’s not impossible to get a newspaper, but it can only be sent by someone, or let the local people post it, etc., which will take a lot of time. Therefore, this encrypted information has a high probability, and the contact is still lurking in Chongqing. Japanese spies."

After hearing this, Han Qiang said: "This analysis is reasonable. And publishing it in newspapers is more likely to contact insurance than using the radio, because as long as we use the radio, we have a high probability of catching it. The spies don't know whether we can now Deciphering their communications. But newspapers are different, who knows who that message was used to contact. It's just... not as timely as radio."

"Timeliness." Qian Jinxun nodded after hearing this, and said, "Old Han's words reminded me that he is a one-line spy. Except for hiding in the Sun God Restaurant for a period of time, when he completes the task, even He doesn't even know when to retreat, and he doesn't even know when to retreat. So that means that the information given to him by Xiaoyun Okubo will be sent whenever he retreats. Does it mean that this information is a follow-up to the launch of this plan? ?”

Fan Keqin thought for a while and said: "Well, I agree. Okubo Xiaoyun didn't say to send him when he arrived in Chongqing, but when he evacuated. Then there is a high probability that this message is a follow-up plan. The most important thing is, As long as you let him send it, it must be related to this mission."

After he finished speaking, the three of them were silent for a while, and Qian Jinxun said, "What if this kid's mission is completed? How can it be related to this confidential information?"

Han Qiang said: "For example, he... I mean for example, for example, this kid knew about the commissioner, or the mansion of Chief Yan, completed the task, sent this information back to the headquarters by radio, and then retreated immediately, and at the same time sent this message to the headquarters. What effect will the encrypted information publish in the Minsheng Daily...? Why am I a bit confused?"

Fan Keqin took a puff of cigarette, put out the remaining cigarette end in the ashtray, and said: "There are too many possibilities, but no matter what, it must be seen."

Qian Jinxun said: "I agree with what you said before, it was for the locals to read, after reading it... what do you mean?"

Fan Keqin said: "Start him? Old Han, can you estimate the number of words in this message?"

Han Qiang said: "Not much. I know there is a way to set it up in advance. For example, a plus sign represents a team of people. But at most it is like this, because one symbol cannot represent double meanings, or there are too many words , otherwise the person who wrote the password might not be able to recognize it, so I feel that this message is at most... twenty characters, or even less!"

Fan Keqin said in a deep voice, "Twenty characters, not even... Well, people who read this message must know this set of passwords, so since it is such a short character, it should not be a routine such as agreeing on the location of the meeting. Information, otherwise it is too rigid, which is not conducive to security. Moreover, the person who wrote this kind of password cannot be used on a large scale. Once it is used too much and too widely, it will be known to us. This time it is indeed our first It’s the first time I’ve encountered this set of ciphers, which can be regarded as proof. So not many people use it... Directly check Okubo Xiaoyun, it should be rewarding, and it won’t take too long to learn this set of full-symbol ciphers. He has been in contact for a long time? It is best to have a name or image information. As long as this name and image appear locally, then whoever must be the spy who received this information."

Han Qiang was taken aback, patted Fan Keqin, and said: "You are a real cow, I never dreamed of this method. It's just...is it feasible to operate?" He said and looked at Qian Jinxun.

Qian Jinxun frowned, and said: "It's feasible, but it's feasible. Isn't Okubo Xiaoyun in Shanghai? We do have spies there, and I can ask them to investigate, but their risk will be greatly increased. I just don't know, take the risk. The results found at the risk of exposure are not worth it."

Fan Keqin said decisively: "Any spy is our biggest bargaining chip, and we can't move it lightly. We have caught this kid now, that is to say, this plan has been destroyed by us. Yoshimune Yamaguchi has not completed the task for a long time , Okubo Xiaoyun will definitely know that something happened to him, and if our spy is too active at this time, the risk of leaking is too high in terms of time. Let's see if we can get something else..." He was talking here when he suddenly stopped.

Qian Jinxun and Han Qiang saw Fan Keqin, staring at the notebook in a daze.For a while, Qian Jinxun and Han Qiang didn't dare to disturb him.After a while Fan Keqin came back to his senses, Qian Jinxun hurriedly asked: "What did you think of?"

Fan Keqin looked at Han Qiang and said, "We don't have a surveillance device now, but can you locate the radio station?"

Han Qiang didn't stutter at all, and replied directly: "In theory, it is possible, but in practice it is very difficult. Because all the spy radio stations that appear will shorten the content to the shortest possible, and strive to complete the transmission as quickly as possible. At this time, I The monitoring team even just heard this signal. So a roughly vague direction is okay, such as an urban area, but the urban area is so big, it’s the same as saying nothing. Unless he sends reports endlessly, then I even Using the most stupid method, you can find him even if you detect the intensity of the frequency, and wander around the city slowly. But how could this happen to the spies of Little Japan? Unless they are all fools."

At this point, he paused, and then said: "I guess you are talking about lateral positioning? I do know how to do this, but it's just using a radio. After all, it's not as good as professional surveillance equipment. The results obtained Still very vague."

After hearing this, Fan Keqin frowned, and said: "That doesn't seem to work." Then he explained: "I think, before Okubo Xiaoyun found out that Yamaguchi Yoshimune had an accident, change this encrypted message and add some symbols to log in. Get out. In this way, what will people think when they read the Minsheng Daily? He will definitely be unsure and think he made a mistake..."
