Preparing Ourselves for the Threats of the Post-Quantum Era.

In the post-quantum era, most of the currently used cryptography is no longer secure due to quantum attacks. Cryptographers are working on several new branches of cryptography that are expected to remain secure in the presence of a universal quantum computer. Lattice-based cryptography is currently the most promising of these branches. The new European PROMETHEUS project will develop the most secure design and implementations of lattice-based cryptographic systems. Exploitation of the project results will be stimulated by demonstrating and validating the techniques in industry-relevant environments.
