v10 Chapter 2109： A performance (1/2)

”In fact, a one-way trapdoor function for exponential power operation is constructed, and the ciphertext C=M^emodn is obtained by calculating the plaintext M.”

”But it is difficult to calculate the base M from the ciphertext C, the exponent e, and the base M. Unless you know the trapdoor information d.”

”...”

With eloquence, Martin Hellman talked about the most important things.

The expressions of the people also changed from blank faces to surprise, to a sudden realization.

There is a saying, the fool is only one teacher away from the genius...

When Martin Hellman led the crowd into the door, everyone suddenly felt a sense of cheerfulness.

It turns out that public key cryptography is not as difficult as imagined.

And the source of this difficulty comes from the threshold!

Yes it is the threshold.

Every profession, every subject has a threshold.

There is an easy-to-understand term for this threshold, called ”entry”.

The people sitting here are all top talents from major universities or major research institutes.

The knowledge contained in their heads is connected, enough to circle the earth twice.

The reason why they find it difficult to face public key cryptography is because they have not crossed the threshold!

Sometimes, to solve a problem is actually very simple, just need to catch the fleeting white dove.

It's just trying to catch him, but it's extremely difficult.

And now, Martin Hellman sent the white dove to everyone.

There is no reason to refuse...

On the stage, the corner of Martin Hellman's mouth was raised, and a faint smile appeared on his face as he watched everyone's suddenly realized expressions.

To be honest, he is very happy, very happy.

Because this is the essence of science.

This is the original intention of his invention of public key encryption technology.
