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.

Efficient Fully homomorphic encryption scheme using Ring-LWE [PDF]
Journal of Physics: Conference Series, 2021 Abstract Data can be stored and processed in an encrypted format using fully homomorphic encryption, which makes cloud computing provider can process data well without even knowing data information. However, most existing homomorphic encryption schemes based on ring learning with errors, focus on the special classes of rings, such as ...
