Definition ∞ An NTRU Linkable Signature is a cryptographic signature scheme derived from the Number Theoretic Research Unit (NTRU) lattice-based cryptography. It allows a signer to produce multiple signatures for the same message that are cryptographically linked, proving they originate from the same source without revealing the signer’s identity. This property aids in preventing impersonation.
Context ∞ NTRU Linkable Signatures are a component of post-quantum cryptography, designed to resist attacks from future quantum computers. Their application in digital asset systems could enhance privacy and security for transactions, offering a solution for verifiable identity without exposing personal data, which is a key area of development for long-term blockchain resilience.
