The existing bastion machine has the problems such as the operation logs being tampered with in the operation and audit process,the administrator has too much power,centralized identity authentication and the resources are not under control.A blockchain-based bastion machine log analysis system is designed and implemented.The logs for management,operation,and au-dit of the fortress is anchored on the block chain by using smart contract and on-chain storage technology.It forms a traceable and tamper-free record.Through the combination of smart contract,digital signature,and other technologies,it provides users with completed information records of the operation and maintenance audit process.It also provides individual companies or judicial insti-tutions with evidence retention and accountability methods for data distortion.According to the system implementation and analysis results,this system can provide auxiliary applications for different customized versions of the existing fortress fighter system.It has the characteristics of immutability,high reliability,and traceability.It also provides new ideas and technical support for the manage-ment,operation,and maintenance for fortress fighter.
