The paper “Accurate and Composable Noise Estimates for CKKS with Application to Exact HE Computation” was published in IACR Communications in Cryptology. The authors are Jean‑Philippe Bossuat, Anamaria Costache, Christian Mouchet, Lea Nürnberger and Juan Ramón Troncoso‑Pastoriza. This publication, developed within the PRIVIDEMA project, advances precise and composable noise estimation techniques for CKKS, enabling more reliable exact homomorphic computations.

The 1st Newsletter of the PRIVIDEMA project has been released. It presents the project`s objectives and the key achievements during the past few months.

Check out the PRIVIDEMA administrative poster, now available for dissemination and communication activities.

The official leaflet of the PRIVIDEMA project is available, containing project information, vision, goals of the project and more.

PRIVIDEMA will focus on developing user-friendly, scalable solutions to enhance cybersecurity across Europe. Find out more in the official announcement letter of PRIVIDEMA project.
