Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

For decades, the quantum threat to RSA and ECC encryption has been tied to Shor’s algorithm and the assumption that we would need million-qubit quantum computers to make it practical. A newly ...

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 ...

The RSA algorithm is based on the mathematical difficulty of factoring the product of two large prime numbers. It involves generating a public and private key pair, where the public key is used for ...

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 ...

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 ...
