摘要
为增强物联网架构的安全性,降低数据传输风险,提出一种新的跨域移动节点安全认证方法。分析物联网节点的物理特征与信任特征,利用网络模块、信誉模块和服务模块搭建信任体系;通过信任初始化、信任更新等过程建立信任模型,计算不同节点之间的信誉程度,以信誉值为安全认证的依据;构建具有应用层、合约层、激励层等结构的区块链架构,引入加密算法,经过不同域服务器之间的相互认证,解析区块链证书是否有效,若有效则认为认证成功;反之,认证失败。实验结果表明,无论网络状态如何,所提方法下节点之间的通信成功率均较高,并且能减少计算开销,提高认证效率,有效加强了物联网信息传输的安全性。
In order to enhance the security of the IoT architecture and reduce data transmission risks,a new method of cross-domain secure authentication for mobile nodes was presented.Firstly,the physical and trust features of IoT nodes were analyzed.Secondly,a trust system was constructed,including network modules,reputation modules,and service modules.Then,a trust model was constructed by trust initialization and trust updating to calculate the degree of trust between different nodes as the basis for secure authentication.Thirdly,a blockchain architecture containing application layer,contract layer and incentive layer,was built.After mutual authentication between different domain servers,the encryption algorithm was introduced to determine whether the blockchain certificate is valid or not.If it is valid,the authentication is considered successful.Otherwise,it fails.The experimental results show that regardless of the network status,the communication success rate between nodes is high,and the proposed method can reduce computational overhead,improve authentication efficiency,and effectively strengthen the security of IoT information transmission.
