WebMar 10, 2024 · Today’s modern cryptographic algorithms derive their strength from the difficulty of solving certain math problems using classical computers or the difficulty of searching for the right secret key or message. Quantum computers, however, work in a fundamentally different way. WebJul 25, 2024 · However, cryptologists agree that one slight problem with RSA remains. At its core, RSA is a simple multiplication equation. While a brute-force attack against RSA would take centuries, a sudden breakthrough in prime number factorization could render the whole technology useless virtually overnight.
