摘要

物联网(IoT)是一个由物理对象组成的网络。这个概念使连接的事物之间的数据交换无需人工干预。然而,由于设备在计算能力、内存存储和能源等方面受到资源的限制,传统的安全加密算法的实现并不适合这些设备。为物联网设备和实施开发轻量级低功耗安全解决方案非常重要。高级加密标准(AES)是广泛使用的标准加密方法,可以考虑为基于物联网的网络提供安全性。然而,标准AES需要在节能和减少实施面积方面进行优化。AES的软件实现方法与高延迟有关。因此,探索AES在受限硬件上的实现是非常重要的。在这项工作中,我们提出了一个8位数据路径的架构,旨在减少硬件实现的面积。

A Study of AES Software Implementation for IoT Systems
The Internet of Things (IoT) is a network of physical objects. This concept enables data exchange between connected things without human intervention. However, the devices being constrained in resources in terms of computing power, memory storage, and energy sources, implementation of traditional security encryption algorithms is not suitable for these devices. It is important to develop light weight low power security solutions for IoT devices and implementations. Advanced Encryption Standard (AES) is the widely used standard encryption method and could be considered to provide security to IoT based networks. However, standard AES needs to be optimised in terms of energy savings, and reduced area for implementation. The approach of software implementation of the AES is associated with high latency. It is, therefore, important to explore the implementation of the AES on hardware in area-restricted way. In this work, we present an architecture of 8-bit data path aiming to achieve reduced area for hardware implementation.
