BFA 2022

The 7th International Workshop on

Boolean Functions and their Applications (BFA)

September 11-16, 2022, Kviknes hotel, Balestrand, Norway

Organized by The Selmer Center

Boolean functions and more generally all the discrete structures used in error correcting coding, cryptography or communications, are highly active areas of research. The workshop Boolean Functions and their Applications (BFA) is to provide a forum for researchers who are working on discrete functions and structures, particularly on Boolean functions, to exchange ideas and interests in open problems, and to further explore their applications in cryptography, error correcting codes and communications.

The event is at the moment planned to be hybrid, that is, both physical and online participation is possible. There is no registration fee for online participation although all participants must register (for physical or for online participation).

All participants who wish to contribute a talk of 15-20 minutes are invited to submit a 4-5 page extended abstract (see submission details below). We request previously unpublished results on all aspects of discrete structures, particularly on Boolean functions and their applications in cryptography, coding theory, combinatorics, quantum computing, etc. Topics include but are not limited to:

  • foundational theory of Boolean functions and discrete structures;
  • the design, proposal, and analysis of cryptographically significant (vectorial) Boolean functions;
  • the theory and construction of quantum Boolean functions;
  • the theory of finite fields and its applications in cryptography and coding theory;
  • the study of applications of (vectorial) Boolean functions to cryptography, codes, and other discrete structures.

After the workshop, all participants will be invited to submit a paper to a special issue on Boolean Functions and their Applications in the journal Cryptography and Communications. You can find the call for papers here.

Travel information

Travel Schedule

Those attending the conference in person can depart by speedboat from Bergen Strandkaiterminalen on Sunday, September 11 at 16:30. The arrival is estimated at 20:30 at Balestrand. The Hotel Kviknes is just a few minutes walk from the pier. The only alternative departure time is 8:00, with an estimated arrival at 11:00. The workshop will end on Friday, September 16. The estimated departure is on Saturday morning at 07:50, with an estimated arrival at 10:55. Alternative departures are at 16:50, either on Friday or Saturday. In these cases, the arrival is estimated at 20:25 at Bergen Strandkaiterminalen.

Tickets can be purchased online.

Travelling by bus or a combination of bus and train is also possible, but not recommended.

N.B.: All times above might be subject to change in the next months. All information above is based on unofficial indications from the ferry operator and the new timetables are not official until next summer. If you are planning to travel on different days, please carefully check the timetables provided by the ferry operator. Mind that published timetables are currently valid only for the months of February, March, and April.

Travel through Bergen Lufthavn

Participants outside of Bergen can reach the city by plane landing at Bergen Lufthavn.

Participants landing in Bergen Lufthavn can use the bybanen to reach the city centre and the Strandkaiterminalen. The bybanen stop is right outside of the airport and you should travel from the airport to “Byparken”, the last stop of the bybanen. Trains travel every 15 minutes for most of the day, but you can also check the timetables provided by the operator, or plan your route using the dedicated route planner app.

The bybanen offers both a route planner app and a ticket purchasing app, that can be downloaded here. The ticket to the city centre is a “Zone A” ticket. Mind that tickets purchased through the App are immediately valid upon purchase, so you should only buy them once you are ready to leave the airport. Tickets can also be purchased at vending machines at the airport.

Travel regulations for entering Norway

To the date of Wed. 16 February, there are no travel restrictions to Norway.

Any changes to these conditions will be reported here, but we strongly advise participants who are not Norwegian residents to make sure if any restrictions apply before travelling using the UDI portal or helsenorge.
