Chapter 2108

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

The corners of his mouth rose, his face was smiling, and his whole body was filled with a breath of confidence.

"Professors, before I speak, I'd like you to understand a concept."

"That's what public key cryptography is!"

"First of all, we should know that public key encryption, also known as an asymmetric encryption technique, belongs to the secondary discipline of network security under communication technology."

"Refers to an encryption method consisting of a corresponding pair of unique keys. It solves the problem of key distribution and management, and is the core of commercial password. In the public key encryption system, what is not disclosed is plaintext, what is public is ciphertext, public key and algorithm

"Before I invented the public key encryption technology, I would like to thank two professors. They are professor dieffey and Professor Herman. They first proposed to create a key for the sender and receiver based on one-way function and one-way secret gate function."

"And I just stand on the shoulders of giants and extend their theories appropriately."

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

With that, Martin Hellman dropped his hands in front of him and made a deep bow to the audience.

"Pa pa pa pa..."

In an instant, thunderous applause rang out in an instant.

Today's science, is standing on the shoulders of giants to advance.

The predecessors laid a foundation, and later generations spread their branches and leaves.

But how many people will remember the contributions of our predecessors when the future generations spread their branches and leaves and add honor to their bodies?

Less! Very few! Very few!

Most of them will choose to take all the honor on themselves, so that their image looks more tall.

But now? Martin Hellman did the opposite.

He was not in a hurry to introduce his achievements, but at the first time thanks to dify and Herman.

Almost no one in the whole academic circle can do this.

Off stage, deephey and Herman looked at each other and laughed. To be honest, they didn't expect Martin Hellman to make such a decision.

When he said this, he shared his honor with others!

To be honest, they are really happy!

The applause lasted for several minutes until Martin Hellman raised the microphone again to give a presentation, and the crowd quieted down.

Martin Hellman's eyebrows were frivolous and exuberant, and he said in a loud voice, "please be quiet, and we will continue with the report."

For an instant, the whole venue was silent.

All eyes were on Martin Hellman.

They know, Martin Hellman talked about dry goods this time.

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

"Construct a large number n = P × Q, P, q are two different prime numbers, then Φ (n) = (p-1) (Q-1). Find a pair of factors in Φ (n), select an integer e "

" that is coprime with Φ (n), "calculate d, make edmod Φ (n) = 1

public key {e, n}, private key {D, n}

encryption: C = m ^ emodn

decryption: M = C ^ dmodn"
