- Cryptanalysis of the Multilinear Map over the Integers. With Jung Hee Cheon, Kyoohyung Han, Changmin Lee and Hansol Ryu.

- Fully Homomophic Encryption over the Integers Revisited. With Jung Hee Cheon.

- Improved security proofs in lattice-based cryptography: using the Rényi divergence rather than the statistical distance. With Shi Bai, Adeline Langlois, Tancrède Lepoint and Ron Steinfeld.

- fplll is a
code distributed under the LGPL that
LLL-reduces euclidean lattices. The code has been written by
Martin Albrecht, David Cadé, Xavier Pujol and
myself. It may be downloaded from GitHub.
