Overview

• NTNU’s system relies on lattice-based NTRU cryptography to withstand attacks by future quantum computers.
• Researchers have proven the design confirms voter eligibility, preserves anonymity and ensures vote tally verifiability on par with pen-and-paper elections.
• The design and mathematical proofs were detailed in the IACR Communications in Cryptology article “More Efficient Lattice-Based Electronic Voting from NTRU.”
• The Norwegian National Security Authority warns there is a better-than-even chance that quantum computers capable of cracking current encryption will appear within 10–15 years.
• Despite fully digital elections in Switzerland, Estonia, France and Australia, Norway will continue using paper ballots until it secures technical refinements and public confidence.
