An Automatic Analysis Approach Toward Indistinguishability of Sampling on the LWE Problem
Tsinghua Science and Technology, 2020 Learning With Errors (LWE) is one of the Non-Polynomial (NP)-hard problems applied in cryptographic primitives against quantum attacks. However, the security and efficiency of schemes based on LWE are closely affected by the error sampling algorithms ...

Secure Single-Server Aggregation with (Poly)Logarithmic Overhead
IACR Cryptology ePrint Archive, 2020 Secure aggregation is a cryptographic primitive that enables a server to learn the sum of the vector inputs of many clients. Bonawitz et al. (CCS 2017) presented a construction that incurs computation and communication for each client linear in the ...

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT The increasing integration of distributed energy resources demands enhanced coordination between transmission system operators (TSOs) and distribution system operators (DSOs) to maintain reliable grid operation. Traditional approaches rely on hierarchical or distributed optimization schemes for power flow management, but these methods either ...
