The potential impact of quantum computing on cryptography is significant, as quantum computers can potentially break traditional encryption methods. Classical cryptographic algorithms, such as RSA and ECC, rely on the difficulty of mathematical problems, which quantum computers can solve much faster due to quantum bits (qubits). This raises concerns about the security of sensitive data and transactions. As a result, researchers are actively developing post-quantum cryptography to protect information against future quantum attacks, emphasizing the need for organizations to transition to more robust security measures.
