Abstract

The impending realization of scalable quantum computers has led to active research in Post Quantum Cryptography (PQC). The challenge is harder for embedded IoT (edge) devices, due to their pervasive diffusion in today’s world as well as their stricter resources (tight area and energy budgets). Amongst various classes of quantum-resistant cryptography schemes, Lattice- based Cryptography (LBC) is emerging as one of the most viable, almost half of the ‘survivors’ of second round of the NIST’s PQC competition are lattice-based in construction. This paper surveys the practicality of deployment of these schemes. In this context, the state-of-the-art LBC implementations on the constrained devices (including low-power FPGAs and embedded microprocessors), leading in terms of low-power footprint, small area, compact bandwidth requirements and high performance is fairly evaluated and bench-marked. The work concludes by identifying a suite of some favorite LBC schemes in terms of various IoT critical performance bench-marks.
量子世界中基于格的物联网加密:我们准备好了吗?
随着可扩展量子计算机的实现,后量子密码学(PQC)的研究日益活跃。嵌入式物联网(边缘)设备面临的挑战更大,因为它们在当今世界的普及以及它们更严格的资源(紧张的面积和能源预算)。在各种类型的抗量子加密方案中,基于晶格的加密(LBC)正在成为最可行的方案之一,NIST第二轮PQC竞赛中几乎一半的“幸存者”都是基于晶格的结构。本文考察了这些方案部署的实用性。在这种情况下,在受限设备(包括低功耗fpga和嵌入式微处理器)上的最先进的LBC实现,在低功耗占用、小面积、紧凑带宽要求和高性能方面处于领先地位,得到了公平的评估和基准测试。最后,根据各种物联网关键性能基准,确定了一套最受欢迎的LBC方案。
