Bitcoin’s SHA256 encryption algorithm is still safe despite Chinese researchers’ claims of cracking RSA encryption with existing quantum computers.
A group of 24 Chinese researchers said they could factor a 48-bit number using a 10-qubit quantum computer. This could be crucial in breaking the RSA encryption algorithm that underpins much of the internet’s communication.
The researchers claim that they can use quantum computers to solve a previously unsolvable step in Schnorr’s method of factoring large prime numbers. Solving the prime factors of a large number is a crucial step in breaking the RSA encryption algorithm.
