EternaX Post-Quantum Glossary
Canonical definitions for post-quantum cryptography, migration risk, and infrastructure terminology used across EternaX research.
PQ-Native
A system where post-quantum authorization is built into the protocol from inception rather than retrofitted later.
Cryptographic Migration Debt
The accumulated financial, operational, and coordination cost of moving from classical signatures to post-quantum authorization.
Information-Theoretic Security
Security not based on computational hardness assumptions and resilient regardless of attacker compute power.
Harvest Now Decrypt Later (HNDL)
Threat model where encrypted data is collected today and decrypted later when quantum capabilities improve.
ML-DSA
NIST-standard post-quantum signature scheme formerly known as Dilithium.
Falcon
Compact post-quantum signature scheme family frequently used as a throughput comparison baseline.
SLH-DSA
Stateless hash-based post-quantum signature standard formerly SPHINCS+.
Auditable Privacy
Privacy model combining confidential transaction data with selective disclosure and verifiable settlement proofs.
Spendable Finality
Time after which a transfer is safely usable for downstream settlement without rollback risk.
RWA Tokenization
Issuance of real-world assets as programmable on-chain representations.
