A.S. will give some remarks (joint work with Hendrik Lenstra) on homomorphic encryption schemes of Smart-Vercauteren and Gentry-Halevi.

S.S. will discuss the paper "A subfield lattice attack on overstretched NTRU assumptions: Cryptanalysis of some FHE and Graded Encoding Schemes" by Martin Albrecht, Shi Bai, Léo Ducas, which is available at: https://eprint.iacr.org/2016/127.pdf
