Quantum computers could crack a common data encryption technique once they have a million qubits, or quantum bits. While this is still well beyond the capabilities of existing quantum computers, this ...

Abstract: We propose a public-key encryption algorithm based on torus automorphisms, which is secure, practical, and can be used for both encryption and digital signature. Software implementation and ...

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

This is a pure (and very very simple) java implementation of the RSA algorithm. One file to show you how RSA works (Euler's formula and Euclid's algorithm).

I refactored the old code I wrote in this project. I changed the way generating input for RSA algorithm. Now it takes 3 or 2 letters and put them in the same chunk of data. It is more secure but since ...

Abstract: RSA algorithm is an asymmetric encryption algorithm used to maintain confidentiality and integrity of data as it is transported across networks. As time has gone on, security and ...
