i want to make signature scheme by pythagoras theorem

What is a signature scheme? Do you mean you want to determine the signature of the metric by inspection of the Pythagorean theorem?

 

[HallsofIvy]

The "signature" of the Pythagorean theorem is "+, +", of course.
$c^2= a^2+ b^2$ so that a distance formula based on that (i.e. the Euclidean plane) would be $ds^2= dx^2+ dy^2$.

oook hallsofivy
Where will I put the message
& what the equation to get x & y

 

[alaoation]

the Signature is a part of the encryption DaleSpam

Okay, now I am lost completely. What does "encription" have to do with a "signature", "Pythagoras", or even "relativity"?

No. That is still not clear. Please elaborate.

A digital signature is a code that you can attach to a message to prove that you're the one who sent it. It's generated using a hash function (a function that takes arbitrary data as input, and generates data of fixed length as output; e.g. 128 bits or 256 bits), and an asymmetric encryption algorithm (i.e. one that uses different keys for encryption and decryption).

The message I want to sign is first passed through the hash function. Then I encrypt the output using my private key. The result of that is called a signature. If I send someone the signature along with the message, he can apply the hash function to the message, and he can decrypt the signature using my public key. If the results of these two operations are the same, he knows that the message came from me. (The fact that he could decrypt the signature using my public key proves that it was encrypted using my private key).

This obviously doesn't have anything with relativity. I don't see how it can have anything to do with right triangles either.

Choose any interesting Pythagorean triangle. 7-24-25 for instance.

Interesting, alaoation. But of course if you post in Special Relativity about signatures you are bound to get something back about metrics. Good thing we've got guys like Fredrik around.
