Quantum Attack Vector

Definition ∞ A quantum attack vector identifies a specific method or pathway through which a quantum computer could compromise a cryptographic system. These vectors exploit the unique computational capabilities of quantum machines to break algorithms considered secure against classical computers. Examples include Shor’s algorithm for factoring large numbers or Grover’s algorithm for searching databases. Understanding these vectors is essential for developing quantum-resistant defenses.
Context ∞ The threat of quantum attack vectors is a growing concern for the security of digital assets and blockchain infrastructure, as current cryptographic standards are vulnerable. News often reports on progress in quantum computing and the urgency of migrating to post-quantum cryptography. Identifying and mitigating these vectors is a critical aspect of preparing for a future where quantum computers are widespread.
