On Dual Lattice Attacks Against Small Secret LWE and Parameter Choices in HElib and SEAL

Explore a detailed analysis of dual lattice attacks targeting small secret Learning with Errors (LWE) and examine parameter selections in HElib and SEAL cryptographic libraries in this 21-minute conference talk presented by Martin R. Albrecht at Eurocrypt 2017. Delve into the intricacies of lattice-based cryptography, focusing on the vulnerabilities of LWE with small secrets and their implications for widely-used homomorphic encryption libraries. Gain insights into potential security risks and learn about the importance of careful parameter choices in maintaining the robustness of lattice-based cryptosystems.
