Post-Quantum Cryptography: Defending Against Tomorrow's Threats Today
Security Boulevard, Wednesday, April 23rd, 2025
Recent advancements in quantum computing are pushing the boundaries of what is possible for technologists and hackers alike.
Quantum computers leverage the principles of quantum mechanics to solve problems exponentially faster than classical computers, rendering current encryption methods useless.
McKinsey forecasts that by 2030, up to 5,000 quantum computers will be operational worldwide, so while they are not yet a mainstream reality, they still pose an immediate threat. Cybercriminals who 'hack now, crack later' can steal encrypted data and decrypt it in the future when quantum computers are readily available.
