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.
