Securing Sui in the Quantum Computing Era

Quantum computing introduces a major threat to current cryptographic standards, particularly RSA and elliptic curve cryptography used in blockchains like Sui. As a response, NIST mandates a shift to quantum-safe encryption by 2035.

Key Ideas

Sui is designed with cryptographic flexibility, allowing it to transition to quantum-resistant algorithms like CRYSTALS-Dilithium for signatures and ML-KEM for public-key encryption.
One should consider strategies to defend against “store now, decrypt later” attacks, especially for sensitive or long-term data.

If your organization handles sensitive data with long confidentiality lifespans, start auditing your cryptographic systems now. Transitioning to Post-Quantum (PQ) encryption can protect against delayed decryption threats and future-proof your product offerings.
