Definition ∞ Code-based cryptography utilizes error-correcting codes to construct cryptographic primitives such as encryption schemes and digital signatures. This class of cryptography relies on the difficulty of decoding general linear codes, a problem considered resistant to attacks from quantum computers. It represents a post-quantum cryptographic approach, offering security assurances against future computational advancements. The security foundation stems from algebraic coding theory.
Context ∞ The discourse surrounding code-based cryptography intensifies as the threat of quantum computing to current cryptographic standards becomes more apparent. Research and development efforts concentrate on improving the efficiency and practicality of these schemes for widespread adoption. The integration of code-based methods into blockchain and digital asset security infrastructure is a critical area of ongoing investigation to secure long-term data integrity.
