A research group has exposed a weakness in CRYSTALS-Kyber, an encryption algorithm that the U.S. National Institute of Standards and Technology (NIST) adopted. The other algorithms the institute adopted were CRYSTALS-Dilithium, FALCON, and SPHINCS+ for digital signatures. The NIST chose these algorithms as quantum-resistant for the organization.
- Researchers identify side channel attacks up to the fifth order in the CRYSTALS-Kyber encryption algorithm.
- Masking is a possible preventive measure against future attacks, but cyclic rotation could be more effective.
- The need for encryption algorithms is on the rise as cybercrime increases every year.
