区块链推动下的物联网安全研究进展

Research progress in iot security driven by blockchain

随着科技的发展,物联网(IoT)成为一个具备极大潜力和影响力的领域,但是IoT设备很容易受到计算、存储和网络容量方面的限制.而且大多数的设备都很容易被攻击和破坏,所以物联网在信息安全方面还存在技术上的挑战.区块链以去中心化、可信赖性和匿名性等特点迅速成为研究热点,在分布式环境中建立信任而不需要授权,这可以一定程度上弥补物联网的弊端.本文着眼于物联网与区块链的结合,论述了区块链推动下的物联网信息安全方面的近期研究进展.

With the development of technology,the Internet of things(IoT) has become a field with great potential and influence,but IoT devices are easily limited by computing,storage and network capacity.Most of the devices are easy to be attacked and destroyed,so there are still technical challenges in the information security of the Internet of things.Blockchain,characterized by decentralization,trustworthiness and anonymity,has quickly become a research hotspot.Trust is established in a distributed environment without authorization,which can make up for the disadvantages of the Internet of things to some extent.This paper focused on the combination of the Internet of things and the blockchain,and the recent research progress was discussed in the information security of the Internet of things driven by the blockchain.
