摘要
轻量化的密码算法及安全协议属于物联网安全体系的关键技术。文章以有序非重复序列为基础,设计了一种轻量化的消息认证码方案,具有开销小、防重放、可追溯等特性,并结合物联网的实际情况研制了低成本的消息认证码生成设备和认证管理系统,通过设备类型的多样化满足物联网密码技术的等级化应用要求。
Lightweight cryptographic algorithms and protocols are the key technologies of the Internet of Things security. Based on ordered and non-repeated sequences, an anti-replacement message authentication code mechanism is designed, which is also low-cost, lightweight and traceable. A practical realization system, including three types of devices, authentication server and management server, is also introduced.
