3D integration with decoy keys shields NTT computations in NIST PQC algorithms from side-channel attacks.

Post-quantum cryptography algorithms selected by NIST remain susceptible to side-channel attacks. The 3D-Shield approach uses 3D hardware stacking to introduce decoy keys and physical shielding. It complements masking and shuffling for NTT operations and is validated on butterfly computation attacks.

Key facts
  • Targets Kyber/ML-KEM, Dilithium/ML-DSA, Falcon/FN-DSA, SPHINCS+/SLH-DSA
  • Uses 3D hardware for shielding
  • Moves computation to dedicated NTT chips
  • Effective against intermediate NTT butterfly attacks
  • Complements existing security measures

Despite their theoretical quantum attack resistance, practical implementations of post-quantum cryptography (PQC) algorithms remain susceptible to side-channel attacks. This includes all standard algorithms selected the National Institute of Standards and Technology (NIST) such as Kyber/ML-KEM, Dilithium/ML-DSA, Falcon/FN-DSA and SPHINCS+/SLH-DSA.
