Post-Quantum Cryptography

Definition ∞ Post-quantum cryptography refers to cryptographic algorithms designed to be secure against attacks by future quantum computers. As quantum computers advance, they pose a threat to current widely used cryptographic methods, such as RSA and ECC. Developing and deploying these new algorithms is crucial for safeguarding sensitive data in the long term.
Context ∞ The transition to post-quantum cryptography is a significant undertaking for the entire digital security landscape, including the cryptocurrency sector. Current efforts are focused on standardizing algorithms and identifying practical deployment strategies to replace vulnerable cryptographic primitives. The primary challenge lies in the widespread adoption and integration of these new cryptographic standards across existing infrastructure before quantum computers become a viable threat.
