On Dual Lattice Attacks Against Small-Secret LWE and Parameter Choices in HElib and SEAL [PDF]
, 2017 We present novel variants of the dual-lattice attack against LWE in the presence of an unusually short secret. These variants are informed by recent progress in BKW-style algorithms for solving LWE.

Provably weak instances of ring-LWE revisited [PDF]
, 2016 In CRYPTO 2015, Elias, Lauter, Ozman and Stange described an attack on the non-dual decision version of the ring learning with errors problem (RLWE) for two special families of defining polynomials, whose construction depends on the modulus q that is ...

Attacks on the Search-RLWE problem with small errors [PDF]
, 2017 The Ring Learning-With-Errors (RLWE) problem shows great promise for post-quantum cryptography and homomorphic encryption. We describe a new attack on the non-dual search RLWE problem with small error widths, using ring homomorphisms to finite fields and
