| Apr 03, 2026 | The Lattice Assumption Zoo just launched! While the list of catalogued is assumptions is not exhaustive yet, the concept and architecture are stable. This project yields the first community-driven approach to systematically catalogue the landscape of lattice-based assumptions, which has seen rapid growth in the past five years. |
| Mar 10, 2026 | Our paper Scalable Registration-Based Encryption from Lattices will be published at S&P’26. We present the first concrete post-quantum instantiation of RBE supporting arbitrary identity spaces and a large number of users with a ciphertext size of 7.0 MB, improving on prior work by three orders of magnitude. More context can be found here. |
| Feb 14, 2026 | Our paper on Tight Reductions for SIS-with-Hints Assumptions was accepted at PKC’26 and provides new reductions between ISIS$_f$, GenISIS$_f$, and their interactive versions, SIS and a GenISIS$_f$ instance, and One-More-ISIS and its randomised variant. More context can be found here. |
| Jan 21, 2026 | qFALL Goes Live: Our library suite for rapid prototyping of lattice-based cryptography is now available on crates.io. qFALL pursues a unique path by focussing on usability and low-effort high-level implementations to support researchers during the design phase, enabling an incremental optimisation workflow by replacing bottlenecks with more optimised submodules. |
