Definition ∞ Ring-LWE security is a cryptographic security property derived from the Ring Learning With Errors problem, a mathematical challenge considered resistant to attacks from quantum computers. This security underpins certain post-quantum cryptographic schemes. These schemes are designed to protect digital data in the quantum computing era. It represents a forward-looking approach to data protection.
Context ∞ As quantum computing advances, the need for post-quantum cryptography, including schemes offering Ring-LWE security, becomes more urgent for securing digital assets and blockchain communications. Researchers are actively working on standardizing these new cryptographic methods. This development is critical for futureproofing digital security infrastructure.
