A Security Remote Command Control Scheme for Industrial Internet of Things
With the increasing demand for intelligence in the industrial field,the Industrial Internet of Things(IIoT)has developed rapidly.IIoT can effectively improve process efficiency and decision quality in industrial production and has broad application prospects.However,in recent years,the security issues of IIoT are gradually becoming well known.A two party collaborative group signature algorithm is designed based on the SM9 identity-based cryptography for the application scenario of remote instruction control,and it is combined with a blockchain to implement a remote secure instruction control scheme for IIoT to ensure the security of remote instruction operations in IIoT.This scheme is based on the national security SM9 standard.The group administrator reviews instructions and collaborates with the user who initiated the instruction-signing request to complete the group signature.The group signature protects the privacy of the signer's identity while allowing the group administrator to publicly disclose the signer's identity when necessary.By introducing blockchain technology,decentralized management of the IIoT platform can be achieved,and command execution history data can be obtained through smart contracts,facilitating subsequent auditing and accountability.In addition,the scheme effectively reduces computational consumption through batch verification during the signature verification stage.The security and performance analysis results show that when the number of signatures exceeds 20,this scheme can reduce the computational load by more than 50%through batch verification.Compared to the comparison scheme,the proposed scheme has higher security and applicability in the IIoT environment.
