London-ish Lattice Coding & Crypto Meetings

Cong Ling and myself are starting London-ish Lattice Coding & Crypto Meetings. Please help us spread the word.

Lattice-based approaches are emerging as a common theme in modern cryptography and coding theory. In communications, they are an indispensable mathematical tool to construct powerful error-correction codes achieving the capacity of wireless channels. In cryptography, they are used to building lattice-based schemes with provable security, better asymptotic efficiency, resilience against quantum attacks and new functionalities such as fully homomorphic encryption.

We are setting up meetings on lattices in cryptography and coding in the London area. 1 These meetings are inspired by similar meetings held in Lyon 2 and are aimed at connecting the two communities in the UK with a common interest in lattices, with a long-term goal of building a synergy of the two fields.

The meetings will consist of several talks on related topics, with a format that will hopefully encourage interaction (e.g. longer than usual time slots).

Tentative program

For details (as they become available) see website.

11:00 – 12:30: Achieving Channel Capacity with Lattice Codes Cong Ling

13:30 – 15:00: Post-Quantum Cryptography Nigel Smart

15:00 – 16:30: Lattice Coding with Applications to Compute-and-Forward Alister Burr

16:30 – 18:00: A Subfield Lattice Attack on Overstretched NTRU Assumptions Martin Albrecht


Room 611

Everyone is welcome. Two caveats:

  1. Speakers are told the audience is somewhat familiar with lattices.
  2. Please send us an email at, so that the size of the room fits with the number of participants.



Our definition of London includes Egham, where Royal Holloway’s main campus is located.

fplll days 1

We’ll have a first fplll coding sprint aka “fplll days” from June 20 to June 24 at ENS Lyon.

The idea of fplll days is inspired by and might follow the format of Sage Days which are semi-regularly organised by the SageMath community. The idea is simply to get a bunch of motivated developers in a room to work on code. Judging from experience in the SageMath community, lots of interesting projects get started and completed.

We intend to combine the coding sprint with the lattice meeting (to be confirmed), so we’d be looking at 3 days of coding plus 2 days of regular lattice meeting. We might organise one talk per coding day, to give people a reason to gather at a given time of the day, but the focus would be very much on working on fplll together.

If you’d like to attend, please send an e-mail to one of the maintainers e.g. me.
