Top of the Great Era

Zhou Buqi said in a low voice: "This end-to-end encryption technology, we can't do it?"

Shen Xiangyang said with a smile: "If you can't do it, you can't do it. If you really want to do it, you can definitely do it, and it can be done in a short time. It depends on whether it is necessary. As far as the current E2EE is concerned, The application on the mobile terminal is still relatively avant-garde, especially for the ultra-large scale with hundreds of millions of users like Helo, it will still be very difficult to apply."

Zhou Buqi raised his eyebrows, "In the final analysis, Helo did not use such a technology."

Shen Xiangyang said: "Firstly, it is a technical consideration. Development is indeed very difficult, and the input-output ratio is too low. The more important thing is actually the product level."

"product?"

"Well, I have communicated with Luqi. Helo is now a product with high popularity among the public. There is no need to rely on innovation to attract users. The most important thing is to maintain product stability and reduce failure rates. And this A kind of E2EE, it may not be stable enough for large-scale application.”

"Wait until the market matures before applying it?"

It's easier to understand Zhou Buqi.

Analysis from the product level is the main reason.

If Helo really needs such a new technology, then no matter how much research and development funds are spent, it should be invested.

Shen Xiangyang said: "Yes, wait and see the feedback from the market, and then make targeted adjustments. For the vast majority of users, they don't care whether the communication message is sent in plain text or encrypted. Moreover, E2EE's The advantages are obvious, but the disadvantages are also obvious.”

Zhou Buqi asked: "What are the shortcomings?"

Shen Xiangyang said with a smile: "Just like e-mail, the encrypted transmission in the past 20 years has been public key system. First, the technical level is relatively simple, and second, it also meets the product requirements. The platform can decrypt all emails with the public key." content, it can effectively distinguish which are valid emails and which are spam emails. This can intelligently help users classify emails and prevent users from being harassed by spam emails.”

Zhou Buqi reacted immediately, and quickly said: "If it is this end-to-end encryption method, the security is stronger and the privacy is better. However, the platform party cannot decrypt the content of the communication. It will inevitably breed a lot of spam!"

Speaking of this, he quickly understood.

In his previous life, he used the iPhone, and one of the most troublesome things was always receiving iMessage spam.It's not spam, it's communication between iPhones.

This kind of spam is very annoying.

At that time, Zhou Buqi didn't know much about technology, so he felt very strange. Why can't even do this well with the strength of Apple?It's not even as good as many Android copycats, the technology is too bad, right?

Now I understand that this is not a poor technique at all.

Quite the contrary, it's Apple's technology too good.

The information transmission between users is encrypted to the extreme, let alone outsiders can't crack it, even Apple itself can't crack it, so that they can't analyze which information is valid and which information is spam.

The technology is too high, but it reduces the user experience of the product.

However, this technical direction will definitely be a major trend in the future.

Traditional SMS should really be phased out.

Secrecy is not enough.

Among other things, sending text messages... First of all, it is impossible to bypass the hurdle of telecom operators. This mode of sending in plain text will become more and more out of the mainstream market.

That is to say, if these telecom operators have a sense of responsibility, they will classify the text messages, which are fraudulent text messages, which are spam text messages, and which are text messages that may involve personal privacy information.

In this way, many crimes based on SMS can be reduced.

There is no need to use the latest E2EE technology, just use the public key model that was used in e-mail 20 years ago.

This involves commercial interests.

SMS is a very important profit-making business for telecom operators. Except for operators in a few countries who simply classify and remind spam SMS, operators in most countries take a disregarded attitude.

For operators, fraudulent SMS, spam SMS, and false SMS are all important guarantees for SMS business revenue.

Just like medical advertisements on search platforms.

I earn my money.

Whoever gets cheated is your own business and has nothing to do with the platform.

Shen Xiangyang said: "Yes, that's what it means. Helo has not applied E2EE technology for the time being, mainly because of product reasons. However, I have already organized a team to conduct research in this direction."

Zhou Buqi quickly thought of something again, and asked, "Ziweixing International has acquired Snapchat, has the news been officially announced?"

"Not yet, there are still some details to be dealt with." Shen Xiangyang knew what he meant, and said with a smile, "Yes, Snapchat has indeed applied E2EE technology now."

Zhou Buqi asked: "How is it?"

Shen Xiangyang shook his head, "Very average... To be precise, it's terrible. Their research on E2EE is too superficial. Even if the transaction is successfully completed in the end, their technical achievements are not of much practical value. They should be all Tear down. My technical team will take over the entire Snapchat technical line."

Zhou Buqi nodded, "After all, Snapchat is just a small company that has just started for more than a year, so it's not surprising that the technology is poor at all."

Shen Xiangyang said: "Well, Lu Qi also discussed this product with me. Snapchat is different from Helo. Snapchat is still in its infancy, and it relies on some gimmicky functions to attract people. Helo doesn't need it, it has already entered the We are in a relatively stable development stage, so we should not be too rash in decision-making, and the choice of technical route should be based on stability.”

"How's the app on Snapchat?"

"So-so, it's just a gimmick."

"Isn't it?"

Zhou Buqi felt that Lao Shen had demoted Snapchat to nothing.

Shen Xiangyang said seriously: "That's true, about three points. First, Snapchat now uses end-to-end encryption selectively. Their technology is too poor and the encryption technology is not mature enough to take care of every user's needs." Every message. So when Snapchat users send ephemeral messages, some may be end-to-end encrypted, and some may still be sent in clear text. I didn’t ask for specific data, but I guess... No more than 5% of messages will be end-to-end encrypted."

Zhou Buqi twitched the corner of his mouth, "It's still in the experimental stage."

Shen Xiangyang said: "Also, the second point is that it cannot be cross-platform. At this stage, Snapchat's end-to-end encryption can only be applied to the iOS system. A user of an Apple phone uses Snapchat to send a message to another Snapchat user of an Apple phone. Sending messages, it may be end-to-end encryption. But their research has not yet involved Android and other platforms.”

After all, it is a start-up company with a small R&D team, little funding, few engineers, and no technical accumulation at all.

It can only be done bit by bit, slowly groping.

Then, Shen Xiangyang said the third point, which is that multiple devices cannot be synchronized.

In short, the application of this technical direction on the mobile terminal is still a very new topic and a very cutting-edge field.Especially when it is applied on a large scale, it will be a very complex project.

Small companies simply can't do it.

The communication products on the market that claim to apply end-to-end encryption technology are basically gimmicks.

Like a lot of liquor marketing, 50-year-old wine... In fact, adding a few drops of 50-year-old wine to a new bottle of wine will make it 50-year-old wine, which can cause looting in the market.

Having said so much, Shen Xiangyang actually has one meaning, Ziweixing International still lacks a lot in the breadth of technology.The acquisition of Yahoo can greatly make up for it at this level!

Yahoo Mail has been playing with encryption for more than 20 years and is very mature.

This can completely provide research and development ideas for the latest end-to-end encryption technology, which is much stronger than Snapchat.
