v10 Chapter 2108： Standing on the shoulders of giants

Martin Hellman stood on the stage like this, holding the microphone, and talking slowly.

The corners of his mouth are raised, his face is smiling, and his body is full of confidence.

"Professors, before I speak, I want to let everyone understand a concept."

"That's what "public key encryption" is!"

"The first thing to know is that public key encryption, also known as an asymmetric encryption method, belongs to the secondary discipline of network security under communication technology."

"It refers to an encryption method composed of a corresponding pair of unique keys. It solves the issue and management of keys and is the core of current commercial cryptography. In the public key encryption system, what is not disclosed is plain text. It’s ciphertext, public key, algorithm."

"Before I invented the public key encryption technology, I would like to thank the two professors. They are: Professor Diffi and Herman, who first proposed the one-way function and the one-way secret door function as the basis. Create a key for the sending and receiving parties."

"And I just stood on the shoulders of giants and extended their theory appropriately."

"Again, I want to send my most sincere thanks to the two professors..."

As he said, Martin Hellman dropped his hands in front of him and bowed deeply to the audience.

"Papa..."

In an instant, thunderous applause sounded instantly.

Nowadays, science can advance on the shoulders of giants.

The predecessors laid the foundation, and the descendants opened up branches and leaves.

But when future generations spread out their branches and honoured themselves, how many people will remember the contributions of their predecessors?

less! very few! Very few!

Most of them will choose to take all the honors on themselves and make their image look taller.

But now? MartinHellman's approach is exactly the opposite.

He was not in a hurry to introduce his achievements, but thanked Diffi and Herman for the first time.

Hardly anyone in the entire academic circle can do this.

In the audience, Diffy and Herman looked at each other and smiled. To be honest, they didn't expect Martin Hellman to make such a decision.

What he said is equivalent to sharing his honor with others!

To be honest, they are really happy!

The enthusiastic applause lasted for several minutes, and when Martin Hellman raised the microphone again and gave a report, everyone was quiet.

Martin Hellman has frivolous eyebrows, and his expression is flying, he said loudly: "Please be quiet, everyone, we report to continue!"

For a moment, the entire venue was silent.

Everyone's eyes fell on Martin Hellman.

They knew that Martin Hellman was going to talk about dry goods this time.

In fact, it is true. This time, Martin Hellman is really talking about dry goods.

"Construct a large number n=p×q, p and q are two different prime numbers, then Φ(n)=(p-1)(q-1). Find a pair of factors in Φ(n), choose An integer e which is relatively prime to Φ(n

"Calculate d so that edmodΦ(n)=1

Public key {e, n}, private key {d, n}

Encryption: C=M^emodn

Decryption: M=C^dmodn"
