The Event

AM-PQC 2026
Workshop on Algebraic Methods in Post-Quantum Cryptography

With this workshop we want to bring together researchers working on applying algebraic techniques for design and cryptanalysis of post-quantum cryptography. We aim to cover contemporary topics in algebraic methods in multivariate, code-based and isogeny-based cryptosystems. Likewise, we aim at assembling a mixed, diverse group with plenty of young motivated researchers and students to present their work and to directly learn and exchange ideas with more senior experts. Thus, the workshop will be composed of invited talks, contributed talks by young researchers and working groups.

Venue

University congress center Ohrid

The University congress center is beautifully located on the shores of Lake Ohrid, in the picturesque village of Dolno Konjsko. Surrounded by nature, it offers an ideal setting for both work and relaxation.
Designed primarily for the faculties and institutes that are part of the University Ss. Cyril and Methodius, the Congress Center welcomes other organizations that wish to use its facilities for conferences, seminars, or other events.
The complex features a spacious 30,000 m² park, private parking and sports field. With all the necessary infrastructure in place, the Congress Center provides not only excellent conditions for academic and professional activities but also a pleasant environment for rest and recreation.

About Ohrid

Ohrid

Ohrid is a town in the southwest of Macedonia, on the shores of the Ohrid Lake, surrounded by high mountains. The altitude of Ohrid Lake is 694 meters. Ohrid is culturally one of the richest towns in the Balkans, and one of the oldest settlments in Europe dating back 8000 years. It was a cultural center during Greek, Roman, and medieval times with well-preserved ruins, churches and buildings from all these periods. In addition, Ohrid lake is the oldest lake in Europe likely existing more than 2 milion years and one of the deepest as well. As a result of this extraordinary combination, Ohrid is one of only 40 sites that are part of UNESCO's World Heritage that are Cultural as well as Natural sites.

Travel

Ohrid is well-connected to international and domestic travelers through two nearby airports, one a few kilometers away, and one 2 hours away in Skopje. In summer, Ohrid Airport, located approximately 10 kilometers from the city center. The journey from the airport to Ohrid takes around 10 minutes by car, and to the Kongress center around 30 minutes.
