Before RSA, secure communication required sharing secret keys, an impossible task at global scale. This is the story of how a trapdoor hidden inside number theory became the invisible infrastructure ...

This article presents a practical implementation of encrypted message exchange between two Raspberry Pi devices using a ...

Every encrypted connection you make online relies on a centuries-old mystery about prime numbers. This is the elegant mathematics behind public key cryptography and why breaking it would take longer ...

The dreaded Q-day could arrive sooner than expected, and when it does, experts say we need to be ready. Reading time 8 minutes In 1994, American mathematician Peter Shor developed a quantum algorithm ...

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 ...

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

Tor has announced improved encryption and security for the circuit traffic by replacing the old tor1 relay encryption algorithm with a new design called Counter Galois Onion (CGO). One reason behind ...

Abstract: The main contribution of this paper is to present an efficient hardware algorithm for RSA encryption/decryption based on Montgomery multiplication. Modern FPGAs have a number of embedded DSP ...

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 ...

A Python package that provides symmetric and asymmetric encryption functions for client applications of the Confy encrypted communication system, as well as prefixes that identify messages and ...
