Washington Examiner. Lattice-based encryption is quantum-safe, says Private AI

Updated: Jun 7, 2023

Quantum computing might still be in its infancy stage but the US government is preparing for the worst. Recently, Washington Examiner reported that some Big Tech companies claim powerful quantum computers could easily break regular computer encryptions within a few minutes or hours compared to the thousands of years that it would take today.

The Washington Examiner piece featured Patricia Thaine, CEO of Private AI, a company that detects and redacts personally identifiable information, is working to fight.

“Quantum-safe means that a quantum algorithm has not yet been discovered, which can solve the hard problem that the scheme is based on in any reasonable amount of time,” Thaine told the Washington Examiner.

One of the models Thaine and Private AI are working on is a lattice-based encryption system.

A lattice-based encryption algorithm is a term used for encryption constructions that consist of lattices, either in the construction itself or in the security proof. Not only is it considered quantum-safe, but it’s “pretty darn cool”, according to Thaine.

Within the privacy tech space this type of shift hasn’t been seen since the large Y2K hysteria. Over the next few years, companies will be changing from quantum-susceptible cryptography to the newer quantum-resistant cryptography.
