网络信息技术的广泛应用是全球经济时代的一个重要特征。Zigbee属于一种全新的网络数据通信技术,Zigbee的产生由电子工业化发展程度而决定。对于无线通信而言,数据传输是主要的需求,针对这一情况,Zigbee能够实现成本低、容量大、安全性高的主要使用目标。由于Zigbee的优势明显,目前已经被应用到多个领域。AES加密算法的实现包括密钥扩展过程和加密过程。本文从二方面阐述了物联网Zigbee组网中安全层AES-128加密算法优化的研究。
The widespread use of Internet information technology is an important feature of the global economy. Zigbee belongs to a new kind of network data communication technology. The production of Zigbee is determined by the degree of development of electronic industrialization. For wireless communication, data transmission is the main demand, in view of this situation, Zigbee can achieve low cost, large capacity, high security and the main target of use. Due to the obvious advantages of Zigbee, it has now been applied to many fields. The implementation of AES encryption algorithm includes key expansion process and encryption process. This article elaborates the optimization of AES-128 encryption algorithm in security layer in Internet of Things Zigbee from two aspects.
