Quantum Security Threats to Encryption Systems: Why RSA and ECC Are No Longer Enough
For nearly fifty years, RSA and ECC have quietly protected your bank logins, medical records, and government secrets. That trust is now expiring. In May 2025, a researcher at Google Quantum AI showed that a 2048-bit RSA key could be cracked by a machine with fewer than a million noisy qubits, roughly twenty times less hardware than the same scientist estimated back in 2019. Problems that once kept attackers out for billions of years are sliding toward solvable in days. Worse, sensitive data is already being stolen and stockpiled for a future decryption payday.
