Design And Implementation Of Intelligent Door Lock Network Security Function Detection System

With the continuous development and innovation of the Internet of Things technology,various intelligent household products have gradually moved from concept to reality.Smart door locks,as one of them,are the first and most important line of defense for family safety and property,and their safety is of the utmost importance.However,the current lock standards are mostly aimed at traditional mechanical locks.Smart door lock manufacturers are still unable to refer to a unified and comprehensive standard to manufacture products,resulting in different technical specifications for current smart door locks,and the security situation is worrying.In addition,there is still no safety detection software specifically for smart door locks.In this context,this paper designs and implements a smart door lock network security function detection system.Main tasks as follows:(1)Through studying and sorting out existing data and research status at home and abroad,combined with the investigation of the technical parameters of smart door locks on the market,the research direction is determined to be the network security detection of smart door locks.The development technology is selected from the aspects of advancement and stability,and the B/S architecture design system is determined to be used,and the SSM frame development system is used to effectively reduce the coupling between various functional modules.(2)A comprehensive demand analysis of the system was carried out,and functional modules such as data packet processing,port scanning,replay attack testing,traffic monitoring,data analysis,etc.were designed,which completely covered the detection requirements of the smart door lock network security function.According to the results of demand analysis,the functions of the system are further refined,each module is individually designed,and a detailed implementation process is given.In order to ensure the authentication security of the system,the project introduced the Spring Security framework.For the problem of slow port scanning,multi-threading technology is used.In addition,this article implements the RFC(Recursive Flow Classification)algorithm through the Java programming language,which can effectively filter out the smart door lock communication data packets in any network environment.(3)According to the design plan,a specific system implementation was completed.By testing each functional module,it is shown that the system can meet the needs of users.In the normal working state of the system,a series of functions such as data packet processing,port scanning,and flow monitoring can be realized,which provides support for the detection of network security functions of smart door locks.
