1. The Threat of Quantum Computing to Current Encryption

Understanding Quantum Computer Capabilities

Quantum computers leverage quantum mechanics to perform computations far beyond the capabilities of classical computers. One of the most significant threats is Shor's algorithm, a quantum algorithm that can efficiently factor large numbers and compute discrete logarithms—the foundations of widely used public-key cryptosystems like RSA and Elliptic Curve Cryptography (ECC).

• Shor's Algorithm: This algorithm poses a direct threat to the security of many widely used encryption methods, potentially rendering them easily breakable.
• Timeframes for Threats: While powerful, fault-tolerant quantum computers are still under development, experts predict that sufficiently powerful machines capable of breaking current encryption could emerge within the next 10-20 years. This timeframe necessitates urgent action to transition to quantum-resistant alternatives.

Vulnerabilities of Existing Cryptographic Systems

The potential for quantum computers to break current encryption poses significant risks across various sectors:

• Finance: Financial transactions, banking systems, and cryptocurrency security are highly vulnerable. Quantum computers could compromise sensitive financial data, leading to massive fraud and financial instability.
• Healthcare: Medical records, patient data, and intellectual property related to pharmaceuticals are at risk. Breaches could lead to identity theft, medical misinformation, and severe financial losses for healthcare institutions.
• Government: National security, classified information, and critical infrastructure are all potential targets. Successful attacks could have catastrophic consequences for national security and public safety.
