Definition ∞ Post-quantum encryption refers to cryptographic algorithms designed to resist attacks from future large-scale quantum computers, which could potentially break many of the encryption methods currently in use. These new algorithms are being developed to secure digital communications and transactions against the computational power of quantum machines. The transition to post-quantum standards is a critical security imperative for long-term data protection. It ensures the continued confidentiality and integrity of digital assets.
Context ∞ Post-quantum encryption is a significant topic in cybersecurity and blockchain news, particularly as the theoretical threat of quantum computing advances. The discussion often involves the ongoing standardization efforts by bodies like NIST to select robust algorithms. While practical quantum computers capable of breaking current cryptography are not yet widely available, the need to prepare for this future threat is urgent due to the “harvest now, decrypt later” risk. Future developments focus on integrating these new cryptographic primitives into existing blockchain protocols and digital asset infrastructure.
