1. Quantum Computing: An Unprecedented Threat
Quantum computing harnesses quantum mechanics, specifically quantum bits (qubits), to perform computations far exceeding classical computers. Quantum supremacy, where quantum computers outperform classical counterparts, threatens existing encryption standards by efficiently solving complex mathematical problems such as factoring large numbers used in RSA encryption. Industries like finance, healthcare, defense, and communications face unprecedented vulnerabilities, potentially allowing attackers to decrypt previously secured data. Historical data encrypted using current methods could become compromised in a scenario known as "harvest now, decrypt later," where adversaries store encrypted data to decrypt when quantum computing matures.
