与传统互联网相比,由于基于SDN的物联网覆盖面更广、连接的设备更多、传输的数据更复杂等原因,还存在很多安全方面的技术挑战。提出了在SDN物联网中加入一个基于区块链的安全层作为安全网关,对进入物联网的数据进行一次性的精确验证,各安全网关作为平等的区块链节点加入区块链系统,结合区块链系统的可追踪和不可篡改性,提高了SDN物联网部署的安全性能和效率。
Compared with the traditional internet
the SDN-based internet of things (IoT) has a wider coverage
more connected devices
more complex data transmission.There are many security technical challenges.The security challenges of SDN-based IoT deployment were firstly analyzed
and then the advantages of blockchain technology in solving those security issues were introduced.Finally
to add a blockchain-based security layer was proposed
which acted as a security gateway
data entering the IoT was verified accurately one time.Each security gateway was added to the blockchain system as an equal blockchain node
combined with the traceability and non-tampering of the blockchain system
the security performance and efficiency of SDN-based IoT deployments was improved.
