Encryption System Protects Data from Quantum Computers


light box, illustration

Researchers at IBM have demonstrated a quantum-proof encryption method called CRYSTALS, the Cryptographic Suite for Algebraic Lattices, that can successfully encrypt a magnetic-tap storage device.

CRYSTALS generates its public and private keys with a family of equations called "lattice problems." The team also developed a CRYSTALS modification that should allow the method to encrypt cloud-based data. The company hopes to use this improvement to render the IBM Cloud quantum-proof by 2020.

IBM also made the system open-source so anyone interested in protecting their data can try it.
