Scloud : a Lightweight LWE-based KEM without Ring/Module Structure
Abstract
We propose Scloud , a lattice-based key encapsulation mechanism (KEM) scheme. The design of Scloud is informed by the following two aspects. Firstly, Scloud is based on the hardness of algebraic-structure-free lattice problems, which avoids potential attacks brought by the algebraic structures. Secondly, Scloud provides sets of light weight parameters, which greatly reduce the complexity of computation and communication complexity while maintaining the required level of security.
